Or: Dimensional Analysis - The easiest way to use first principleEver since I came across it, I have been amazed by the utility and power of dimensional analysis. While many engineers vaguely recall if from their degrees as “some fluid mechanics thing”, I have used it to assess noise generated by spa pumps; optimise machine elements; augment the Design Of Experiments (DOE); review the potential to change a pressure sensor design; recall a formula in an exam that did not have a formula sheet, but did list key constants and their units; and assess the potential of a universe with different fundamental laws.
Because it can do so much more for engineers than would “some fluid mechanics thing”, it is a tool that any global engineer should master so that they can quickly adapt to new challenges. And that’s why dimensional analysis is the topic of this article. The Universe Does Not Know What a Kilogram Is The first thing to understand is that dimensional analysis is not really about units. That might sound wrong because it is often taught as though it is about units. You check that metres are on both sides of an equation. You make sure seconds cancel out. You confirm that you haven’t added a force to a velocity and hoped nobody would notice. That’s useful. But it is not the main power of the technique. The real power is that dimensional analysis gets underneath the units. The universe does not know what a metre is. It does not know what a mile is. It does not know what a second is or what a kilogram is. These are human inventions. They are labels we use so we can communicate consistently with one another. But the universe does understand relationships. It understands ratios. If a pendulum behaves a certain way, it does not behave that way because we measured its length in metres instead of feet. If a structure vibrates at a certain frequency, it does not care if the mass was recorded in kilograms or pounds. If a fluid produces drag, it does not care if the engineer prefers SI units or imperial units. The phenomenon is the phenomenon. Our units are just our way of describing it. Dimensional analysis works because it forces us to describe physical systems in a way that is independent of our arbitrary measuring sticks. It asks: what are the fundamental types of things involved here? Length. Time. Mass. Temperature. Charge. Maybe a few others depending on the problem. Then it asks: what combinations of these things can actually matter? That question is far more powerful than it first appears. It is so powerful that even if the universe were to reform with different laws, dimensional analysis would still work. The laws might be different, but once there are quantities that interact, those quantities would still need to relate to each other in dimensionally consistent ways. This is why it feels like cheating. You can sometimes know something must be true before you know why it is true. Rayleigh Knew This This is not a new trick. Lord Rayleigh used dimensional reasoning in the development of what is now often called Rayleigh’s method of dimensional analysis. He used it to explain why the sky is blue. His method is one of the classic approaches taught alongside the Buckingham Pi theorem, and Rayleigh’s method is commonly described as an early method of dimensional analysis. In simple terms, Rayleigh’s method assumes that the dependent variable in a physical problem can be expressed as a product of the relevant independent variables, each raised to some power. You then solve for those powers by requiring the dimensions on both sides to match. That sounds like a mathematical trick. And in one sense it is. But it is also more than that. It is a way of letting the structure of reality constrain your thinking before you do any testing. It tells you what forms of relationships are possible and what forms are impossible. That is the part many engineers miss. They think dimensional analysis is just something you use when you cannot remember the formula. But it is really something you use when no formula exists. Why People Think It Is Only a Fluid Mechanics Thing The reason many engineers think of dimensional analysis as “some fluid mechanics thing” is understandable. It is used heavily in fluid mechanics because fluid mechanics is hard. In fact, turbulence is so difficult that even with modern mathematics and computing power, we still cannot simply solve many turbulent flow problems from first principles in the nice clean way we might like to. So fluid mechanics needed dimensional analysis. Engineers needed Reynolds number, Mach number, Froude number, Nusselt number, Prandtl number and many others because we needed a way to understand and compare systems that were too complex to solve directly. This is where dimensional analysis became famous. But this also created a problem. Because people saw the technique being used in fluid mechanics, they assumed the technique belonged to fluid mechanics. That is like seeing a spanner used on a car and deciding spanners are only for cars. The tool was useful there because the problems were hard there. That does not mean the tool is limited to that domain. Dimensional analysis can apply anywhere physical variables interact. Machines. Structures. Heat transfer. Acoustics. Electromagnetics. Manufacturing systems. Biological systems. Economic systems even, if you are careful with what you mean by dimensions. And that should get your attention. Because global engineers are constantly being thrown into systems they have not seen before. Why Scientists Often Do Not Seem to Use It There is something else interesting about dimensional analysis. It gives insight without always explaining the mechanism. That makes it extremely useful for engineers, but perhaps less satisfying for scientists. A scientist often wants to know why. Why does the system behave this way? What is the underlying mechanism? What is the causal structure? What is the theory beneath it? And that is appropriate. That is science. But engineers often need something slightly different. An engineer needs to know what to do next. Can I scale this? Can I reduce this? Can I make this quieter? Can I make this cheaper? Can I make this more reliable? Can I change this variable and get enough benefit to justify the cost? Of course, the engineer would also like to know why. But if the bridge needs to stand up, the pump needs to be quieter, or the machine element needs to survive another duty cycle, then insight that supports a decision is already valuable. This might be why dimensional analysis seems underused in scientific research. I have only seen one paper where dimensional analysis was used in a way that really stood out to me, and I have only heard one physicist talk directly about using it as a research tool. That does not mean scientists do not use it. Clearly some do. But it does mean it does not seem to be emphasised as much as its power would suggest. Engineers should not make the same mistake. We do not need to wait until we can fully explain the phenomenon before using the insight. How Engineers Can Use It So how should an engineer actually use dimensional analysis? The first use is to partially solve the relationship between variables. Suppose you think a result depends on five or six variables. Without dimensional analysis, you might feel you need to test all combinations. That quickly becomes impossible. If each variable has several levels, your experiment count explodes. But dimensional analysis can reduce the number of variables by combining them into dimensionless groups. This does not usually solve the whole problem. You may still need experiments. You may still need simulation. You may still need judgement. But you need far fewer experiments than you would have needed otherwise. This is where it works beautifully with Design of Experiments. Instead of designing experiments around raw variables, you can design experiments around dimensionless groups. You are then testing the structure of the phenomenon more directly. It also works well with simulation. If physical testing is expensive, slow, or difficult, then simulations can be used to explore the reduced relationship. You can use dimensional analysis to define the form of the problem and then use simulation to fill in the missing functional relationship. That gives you something very close to a formula for optimisation. Not a perfect formula necessarily. But a useful one. And useful is often what engineering needs. Finding the Levers That Matter Dimensional analysis can also tell you which dimensions you can change to get the effect you want. This is one of the most valuable engineering uses. Some variables give you much more bang for the buck than others. If a quantity depends on one variable squared, another variable to the half power, and another variable inversely, then you now know something important. You know where the leverage is likely to be. This helps prevent wasted effort. Engineers can spend a lot of time changing things that are easy to change, rather than changing the things that matter. Dimensional analysis helps you see the structure of the problem before you fall into that trap. It can tell you:
Especially when you are looking at a system you have never seen before. The Global Engineer Advantage This is why dimensional analysis belongs in the toolkit of the global engineer. A global engineer cannot rely only on familiar systems. You might find yourself working on a manufacturing problem in one country, a maintenance problem in another, a product issue somewhere else, and then a forensic investigation in a completely different industry. You will not always have the right formula. You will not always have the right standard. You will not always have someone nearby who has seen the problem before. So what do you do? You start from first principles. But first principles can be slow if you try to derive everything from scratch. Dimensional analysis gives you a shortcut. It lets you frame the problem quickly. It helps you identify the variables. It helps you reduce the complexity. It helps you see where experimentation or simulation should be focused. Dimensional analysis does not make you clever by itself. But it gives a clever engineer a way to move faster through unfamiliar territory. And that is exactly what global engineering demands. How to Master It I cannot explain dimensional analysis fully here. If I tried, this article would become a textbook chapter, and probably not a very good one. But I do hope I have motivated you to take it seriously. Not as something you vaguely remember from fluid mechanics. Not as a unit-checking exercise. Not as an academic trick. But as one of the most powerful first-principles tools available to engineers. If you do want to master it, then I strongly recommend having Applied Dimensional Analysis and Modeling by Thomas Szirtes in your book collection. The book provides mathematical background, procedures, and a wide range of engineering and applied science applications for dimensional analysis and dimensional modelling. Dimensional analysis is one of those tools that can change how you see engineering problems. Once you get used to thinking dimensionally, you start seeing hidden structure everywhere. And it might be one of the easiest ways to start using first principles properly.

Or: How to Have Your Cake and Eat It TooThere are some things in engineering that are very counterintuitive that, if not fully understood, prevent engineers from doing their best work. These perceived paradoxes can limit or misdirect your thinking such that you are not the engineer you can be. In this article, I am going to share two examples of this and then introduce a maxim that can help you with this.
Example 1 – quality is cheap The above statement seems very counterintuitive; indeed, it is the case that you can often cut back costs at the expense of quality. However, when a system is easy to implement, making it cheaper to realise, there is also less chance of a mistake being made, meaning quality is higher. This was one of the reasons Toyota was so successful in the automotive industry – by focusing on making things easier to produce for higher quality, they also became cheaper. The opposite was true as well. By cutting out waste (wasted time, wasted parts, wasted steps) to reduce cost, there was less that could go wrong so quality increased. This is not to dismiss the importance of more expensive items when needed, but often they will be cheaper in the long run anyway. It’s just that engineers can sometimes give themselves false assurity by choosing the more expensive option. Example 2 – simple code can do more than A.I. One would think that with more lines of code and a complex algorithm there would be more going on so it can do more. But code that has been written explicitly can be tuned so that it achieves the exact goal desired. If a trained ML system does something wrong, then you likely have no idea what’s causing the issue. All you can do is make a few adjustments to the training system, retrain, and hope for the best. If, on the other hand, you have explicit code, then you can understand what’s happening (or not happening), and make changes to improve performance. This is not to be dismissive of things A.I. Comparing ELIZA to what’s on offer today shows how powerful A.I. systems have become. It is more that we can think A.I., because of its complexity, will be the better option regardless. But still, when one considers the success in the early 1970s of much simpler systems – such as the one documented by F. T. de Dombal et al. in Computer‑Aided Diagnosis of Acute Abdominal Pain where a relatively simple program outperformed senior specialists (91% success vs 80%) – there is the potential for simpler code to do more. What is missing in engineering thought for this to happen? It can be found in the 1920s. For some time, it could not be determined if light was a wave or a particle. It had properties of each – depending upon the test. However, by the 1920s, it was accepted that light was both a wave and a particle. The “OR” was replaced with the “AND”. And that’s the key thinking difference you need to adopt. Stop thinking things like:
Instead start thinking things like:
In short, stop asking the “OR” questions and start asking the “AND” questions. Make this a habit, and you will start producing better engineering outcomes – because you will not full into traps of intuition. Everyone wants to have their cake and eat it too. And engineers should be trying to make that happen! Or: Make Time Work for YouIf you want to become a great engineer (particularly a great global engineer), then there is one capability that matters more than most people realise.
It is not domain knowledge. It is not even intelligence. Most people think of those. It is your relationship with time. This idea is explored in The Time Paradox, by Philip Zimbardo and John Boyd. I also noted this in my book. The Time Paradox examines how people orient themselves toward the past, present, and future; and how those orientations shape behaviour, achievement, and satisfaction. The important orientation I am talking about here is the future focus – because of its link to successful people. The key to the future focus is the attitude that what you do now will pay off in the future. You don’t try to frame problems, or apply first principles, or think systemically, see no immediate change in outcome, and then think: well, that didn’t work; what a waste of time! You work on these skills now, and tomorrow and the day after that. Knowing that each time you do, you get a bit better at it. If you go to the gym each day and lift weights, then you’re going to get muscles. If you keep on working deliberately on developing core engineering skills, then you’re going to become an excellent engineer – and keep getting better. You probably already have a strong future focus – but there is likely room for improvement. Because you are an engineer, you had to get through your degree. You gave up a significant number of years to invest in your engineering knowledge for a better outcome. Still, you might have just taken it one step at a time or simply responded to each task put in front of you during your studies – viewing this time as a student as simply what you do and making the most of the present. Think now about how you viewed this when you studied. Were you thinking about how each action was going to make for a better future or were you just doing what you did and making the most out of your situation at the time? This will help you work out your future focus tendency. Does it work? Have you ever noticed some people who are not that bright, but have still been successful? You have likely come across people where you have thought “How did they get to that level?” They simply do not seem to have that much going on upstairs and yet they have a senior role. They might have been lucky, but the likely had a strong future focus. So they were able to keep on working on mastering key skills that were needed to get the role they wanted – and they are probably still working on getting the next role. That can be you! But what could be stopping you from having this perspective. Have you ever met someone who just seems to react to everything? They don’t plan, they never seem organised, and they never seem to just pull it together. These are people who have no future perspective. The things that rob people of a future perspective are:
If your background does encourage a future focus, then you can probably still improve it further. You have likely heard about the idea that you need ten thousand hours (or ten years) of practice to become skilled at something. So you likely know, logically, that time is needed. But is it having a strong future focus that allows you actually to put that time in – and keep at it after that. So think now about maintaining a future focus so you can stay on the journey to engineering excellence and all that will come from it – be it material or personal gratification. Or: How you can instantly become the old guy who has seen it all!As an engineer, you probably don’t like the documentation side of things. You should at least see its value, but, in my experience, engineers are usually not fans.
We know that it protects the organisation, supports future work, and helps others understand what we have done. And yet, under time pressure, documentation is often the first thing to be condensed, deferred, or quietly abandoned. This is not new. But there is going to be a new pressure to create even more documentation. Not because management suddenly cares more. Not because standards have become dramatically stricter. But because the value of documentation has fundamentally changed. And it’s because of AI. How AI Will Make Documentation More Valuable Historically, documentation has been hard to use well. It was often written because it needed to be and then just left. People might refer to meeting minutes to double-check their deliverables. But usually, it would be left until there was an audit or something official like that. And that meant it was written in a way that was only useful for such things. Which in turn meant that it was hard to use for other things. Things like:
AI changes that completely. With comprehensive documentation of an engineering project (design decisions, options considered, trade studies, constraints, assumptions, experiments tried, and outcomes), it is possible to interrogate all of it quickly. Not by reading everything line by line, but by asking the question you want answered. Interrogating Engineering History Imagine you are looking at an existing engineering system and considering a change. If you have good documentation, you can now ask an AI system questions like:
This documentation becomes your operational knowledge. You won’t repeat the same mistakes and you can better assess new ideas with the knowledge you now have. It’s like you have become the old guy in the company who has seen it all! Documentation Will Be Demanded More – Because It’s Easier There is definitely a certain irony here. The same technology that makes documentation more valuable also makes it easier to produce. Engineers can now:
And once that happens, the expectation will shift. If documentation is easy and highly valuable, it becomes harder to justify not doing it. For the Global Engineer (and Company) This matters even more in a global engineering context. When documentation exists, AI allows it to be repurposed for different audiences. Language barriers are reduced. Differences in writing style, cultural expectations, and technical depth can be adapted on demand. That means documentation no longer has to be perfect for everyone. It just has to exist. Making it easier again for an engineer to work anywhere in the world. It also means an engineering company can be more robust. Engineering teams change – sometimes when you least expect it. People get reassigned. Projects ramp down. An entire engineering team gets taken out by food poisoning at a corporate barbecue. When a new team comes in, good documentation plus AI dramatically reduces the recovery time. New engineers can interrogate the history of the project instead of starting with fragments and assumptions. Think about all the lunar exploration knowledge that needs to be relearned with the recent efforts to return to the Moon. Knowledge that can be reused, transferred, explained, and interrogated is far more valuable than knowledge locked inside a few people’s heads. When all past experience within a company is documented and easy to use, it increases the value of the company’s intellectual property by orders of magnitude. And an engineering firm would be foolish not to demand all knowledge now be documented. The Shift That’s Coming Engineers are probably going to be asked to document more than they ever have before. You might not like it. You might resist. But, as the above shows, the payoff will be real. The best you can do now is start using AI to make this documentation easier to generate and then be mindful to use AI to access that documentation (and others) in the future. Or – Death to meetings!Let’s talk about how you can use an old and well-established technique to bring your team of engineers (no matter where on the globe they hail from) into alignment of understanding. And without the need for time-consuming meetings that no one seems to be mentally present at anyway.
Recently there have been stories about how Jensen Huang reads a huge number of emails each morning. The story is likely exaggerated – a calculation of the implication of the claims indicates that he would not really be reading the emails. However, there are details about the nature of the emails – written so that the key points can be extracted quickly – and how this allows for a much flatter company structure - Jensen Huang can quickly distil key information for situational awareness without the need for middle management or excessive and wasteful meetings. He has been described by some as revolutionising management. But is this really anything new? Not really – it is a variation on the theme of the established one-pager. The one-pager you say? The one-pager has been a tool of business and management for so long it is hard to establish the origin. That’s an indicator of how powerful it can be. Yet many still do not understand the power, and do not use this remarkable tool. Why is the one-pager so powerful? It comes down to two things: the speed of talking and the speed of reading. People can speak about 150 words a minute. They can read up to 300 words a minute. You can see the power already. If, instead of asking people to present in a meeting, you ask them to write a one-pager for others to read, then you have just halved the time demands on each person involved. But there is even more benefit. Each person can read at a time that suits – allowing them to better manage their time in general. They also focus when they read – instead of sitting in a meeting looking like they are paying attention when they are not (especially if the meeting is an online one when everyone is working on other things anyway). And not the disadvantages you might assume. You might assume the use of the one-pager is a one-way thing: no chance to ask questions. But, after reading a series of one-pagers, you, and others, can follow up if needed. Maybe even call a meeting – but this time you know that meeting will be focused, and of greater value. Excellent record keeping. If you have a repository of one-pagers for any engineering project or activities, then you have a great record of efforts. This can be excellent to review why certain things have been done, find how to resolve issues solved prior, and to prepare for stage gate presentations or audits. Nuances in the global context. If you do choose to try the one-pager in a global context, then you will find that different cultures will write them differently. And none of them will be ideal. Western-style. Tell ‘em what you are going to tell ‘em, tell ‘em, and then tell ‘em what you told ‘em. The use of this tricolon method does help to drill the point. But it does also mean space has been wasted – you do have only one page after all. Confucian style. Spiral to the point. Cover the various aspects of concern as you slowly get to your point – like exploring the whole landscape so nothing is missed. It is a good way to ensure coverage, but, as we will learn, it is good to be upfront with the point. Arabic style. The zigzagging of iteration. The traditional Arabic approach is start each section with a summary of the last and how it links to the new one. It is indeed good to note interconnectedness, but there is limited space so best to be concise. The ideal style of the one-pager. Start with the main points to be conveyed. That helps the reader determine if they need to read more – thus saving people even more time. This section should include any thoughts on how others could be affected – so you can be more sure people will know if they need to read on. It should also include what support, if any, is needed from others – you won’t get help if you don’t ask. Next, provide the detailed information to support the above. There should be no new information here – just details to better explain what has been said. And it could include images, but do not use up too much space. You can of course stipulate any format you wish. But be careful. When you are too prescriptive other engineers lose their initiative, you can waste space on things that are not important, and you might not get all the details that are actually relevant. A truly ideal application for AI in global engineering. “I apologize for such a long letter - I didn't have time to write a short one.” ― Mark Twain It does take time to write a concise one-pager. Not much more than it should take to prepare for a presentation in a meeting, but time, nonetheless. So anything that can help with that is ideal. And AI is excellent at taking a list of thoughts, ideas, questions and so on, and then turning them into a polished concise document. I use it frequently in meetings to take people’s individual comments and then turn them into topic-based meeting minutes in an instant. Not to mention auto-reviewing. I mentioned above how a collection of one-pagers can make a great record of an engineering project or be used for audits. Well, you can use AI for these things too. If all the one-pagers are fed into an AI system, then you can:
And it can translate too! So anyone in your team can write in any language they like, then have it translated into the language the team uses. It can then also be translated into the reader’s language to help further again to enhance understanding. You can see now the power of the one-pager as an alternative to having someone(s) present in a meeting – especially as a global engineer. So if you have ongoing meetings where people update their efforts and you think are not doing their job well, or, people seem to waste time calling a meeting each time they have an issue, then try the one-pager method. Suggest a layout and encourage people to use AI to help. Is being a good engineer enough? Is being a global engineer better than being a good engineer?11/4/2026 Or: How competence can hold you backThis newsletter is all about how you can be the sort of engineer who can work, and be valuable, in any company in any part of the world.
Obviously, to do this, you need to be a good engineer. But is that all? This edition is about how being a good engineer can actually limit your ability to be a global engineer. How is this so? An interesting piece of research that I note in my book – The Global Engineer – found that people who are competent often fail when deployed in new cultures and places whereas those who are less competent show higher levels of success. Why is this? The research found that competent people were unaccustomed to finding things difficult. Because of their competence, life had, on the whole, been easy. Then, in a new environment, where they had less experience, they encountered challenges. This made them feel less adequate – a new feeling for them and one that is unpleasant. They simply could not handle this – and they quit. Less competent people, who had numerous struggles in life, were, on the other hand, robust. They were familiar with these experiences and the associated feelings. Because of this familiarity, they knew how to push through and carry on. Thus, they were more successful. The lesson for the global engineer? Yes, you should always work on your engineering skills. You might even be lucky enough to have had them all the time – or at least for long enough that you can’t recall being incompetent. But, if you do wish to ply those skills in a new context, then be ready for a period of discomfort and displeasure – the type that makes you feel less than you used to feel about yourself and question if you were ever truly a good engineer in the first place. Ask yourself now these two questions:
For all your engineering ability, it might be this mental toughness, needed to get through such periods, that actually makes you a global engineer. Or: why a diverse team is a good engineering teamHow do you have the best engineering team? You might, depending upon your age (or your children’s age) know the song We’re all fruit salad by The Wiggles. The lyrics note that you can’t make the perfect fruit salad with only one fruit. You need a lot of different types of fruit. Also, in the lyrics, it is noted that the fruit bowl is the world. Meaning the world is a better place with diversity. But the analogy does apply when the bowl is an engineering department as well.
If you want an excellent team, then it too should be like fruit salad. Why is this so? There are two reasons:
So next time you are putting an engineering team together, or looking to join an engineering team likely to succeed, make sure it is diverse. In as many ways as possible, country of origin, place of education, places worked, age, sex, and anything else that makes engineers different. Of course, you can and should always be working on broadening your own engineering skills, experiences and knowledge. And so should the others in your team (no matter how diverse it might or might not be). You and your colleagues will each be more well rounded bowls of fruit salad, but it always helps to have a bigger bowl with more fruits. A recent paper published in The Review of Financial Economics has found that engineers make better CEO. I am sure this is a good boost to your ego right about now, but I thought it would be good to explore this more. This will help better understand what it is to be an engineer and what career options you can consier moving forward.
Fist, the details about the article. The article, Engineering leadership: A human capital, cognitive‑fit, and innovation diffusion perspective on CEO financial performance, was written by Ehsan Danesh and published earlier this year. In it, the author examines Fortune 500 firms (2019–2024) and reports that companies led by engineering‑educated CEOs outperform peers on ROA, ROE and net‑income growth, with stronger effects when the CEO has deeper technical education from a second degree. Why might that be? In The Global Engineer I argue that three capabilities sit beneath good engineering: first‑principles reasoning, systems thinking, and framing. These aren’t confined to heat‑transfer, structures, or circuits; they transfer to organisation management just as well. They help you strip away noise, see interactions and constraints, and define the real problem before allocating effort. The kind of stuff senior leaders should do when planning what to do next. It’s also a useful reminder of what a CEO is actually expected to do: set direction under uncertainty, allocate capital across competing options, manage risk explicitly rather than implicitly, and maintain the ability to course‑correct when the system pushes back. Engineers practice this every day: quantify assumptions, evaluate trade‑offs, and take deliberate risk where it is justified. This consistent with what the research found: the performance differences appear where disciplined analysis and adoption of better ways of working compound. So, if you’re an engineer, take leadership seriously as a future path. You’ll still need to learn finance, governance, incentive design, and stakeholder work, but the underlying structure of your thinking already matches the job. For what it’s worth, I also have a business master’s; it taught me a lot, yet I frequently found my engineering skills providing an excellent base to process and use that knowledge. Finally, for investors, leadership background is one sensible signal to evaluate a company. When a company appoints an engineer as CEO it’s reasonable to anticipate a different and better approach to problem framing, innovation adoption, and capital allocation. The study suggests those differences can show up in the numbers. So it’s a good indicator of when to buy. Or: How to have even more fun in engineeringFrom one perspective, all engineers sit somewhere on a particular spectrum. At one end are those who chase the parts of engineering they personally enjoy – often the stereotypical ones. At the other are those who understand the value, satisfaction, and deep quiet pleasure that comes from embracing the entirety of the craft. The child engineer thrives on the simple. They enjoy the burst of creativity when ideas flow, the thrill of possibility, and the fun of imagining solutions. They love the start of the adventure. But once the idea is “basically there”? They can’t imagine what comes next or the importance of it, for they are children, and their interest fades. They want to move on to the next idea, the next spark, the next moment of juvenile novelty. The adult engineer, however, has, some time ago, discovered the joy in a broader landscape. They still enjoy ideation. And they also appreciate the deeper, richer pleasures (those that come from seeing an idea all the way through to a proper solution). They take satisfaction in shaping a concept into something real: optimising it so it is efficient to implement, verifying that it is safe when built, ensuring it meets every peripheral need that others down the chain rely on. They document it properly, not because they “have to,” but because this is part of creating something fully formed. They understand that professionalism, like adulthood, carries pleasures that are less obvious to the inexperienced, but far more substantial. This reminds me of a quote from a man called John Edmondson. He was an advocate of antioxidants and physical challenges – at 47 years of age he managed 5,000 push-ups in 3hrs 18mins. He once said, “winning is boys; killing is for men.” By “killing” he meant killing the challenge in front of you – such as 5,000 push-up or the hill you plan to run up. It could also mean the engineering challenge in front of you. The child engineer will win by coming up with an idea. The adult engineer will kill the challenge – and implement a total solution. Other contrasts between the child engineer and the adult engineerThe child engineer will complain loudly about tasks they dislike. They will avoid procedures because “they’re annoying,” or try to work around company standards simply because they’d rather not deal with them. The adult engineer sees these procedures differently. They recognise that standard process is what allows whole organisations to collaborate without chaos. They follow the procedure because doing so supports others. And when they know the procedure is flawed, they challenge it properly, lobby for improvement, and strengthen the system for everyone. A child engineer has a narrow view of what engineering is: they see themselves as someone who “works on the thing and invents things.” The adult engineer sees engineering as a profession. They think about framing problems correctly, applying first principles, checking assumptions, engaging the right stakeholders, and understanding how their decision today affects manufacturing, construction, quality, service, regulations and safety tomorrow. They experience engineering in its full, interconnected richness—and they enjoy that broader horizon. It is the difference between juvenile pleasures and adult pleasures: both are real, but only one offers lasting depth. And then there is how they engage others. The child engineer expects others to package information for them in an easy-to-digest way. They share their own information however they like and assume everyone else will interpret it correctly. The adult engineer takes the time to understand what other teams need, adjusts their communication accordingly, and gives people what they require to progress. They also push back when others try to offload their responsibilities onto them—not out of defiance, but because professionalism is reciprocal. This notion of the adult engineer is universal. These are the engineers who thrive in global environments, where assumptions differ, cultures vary, and clarity, discipline, and respect for process matter even more. The comparative mythologist, Joseph Campbell, spent his life studying patterns that show up everywhere in human experience: archetypal behaviours that transcend local context. The transition from childlike enthusiasm to adult responsibility is one of them – it happens everywhere. And it is exactly this adult mode of operating that allows an engineer to be effective anywhere in the world. If you are an engineering managerThe distinctions in this article are an excellent reference for your team. Many engineers simply haven’t had someone frame the difference for them. They may not even realise how often they operate as child engineers. Not because of immaturity, but because no one has ever shown them the deeper pleasures of the full craft. Sharing this with them invites growth. If you want to grow as an engineerTake a moment now to reflect on where you sit on this spectrum. Think through the last few weeks of your work. Did you lean toward the tasks you enjoy, or the tasks that were needed? Did you shape the entire engineering journey, or just the parts that felt good? Did you help the organisation function, or make it bend around you? Also, consider your environment. Some managers prefer their engineers to remain childlike. This can be a result of culture as well – those that are more authoritarian. Children don’t push back, they don’t question weak processes, and they don’t challenge assumptions – making it easier for a manager to maintain authority. This can feel comfortable for a manager, but it limits you. If your environment rewards you for staying a child engineer rather than growing into an adult one, you may need to consider whether your development requires moving on. There is far more pleasure in embracing engineering in its complete form. The breadth. The responsibility. The discipline. The craft. The influence. The impact. So where do you sit on the spectrum? Do you know some child engineers? Or: Seriously; Do you even think!?!In this article I am going to talk about a common phenomenon that has afflicted at least one engineer (usually more) in every company I have worked for. It affects engineers (and others) around the world.
And it might affect you! And if so, then you want to know it – and how to overcome it. Because this phenomenon is practically the first key thing you need to overcome if you wish to be a global engineer. In fact, once you crack this, the rest is fairly easy. Which is why it is so sad to see engineers who have been limited by the phenomenon their entire careers – and never progressing as much as they otherwise could have. So what is this phenomenon? It has been described by numerous people in different ways with different perspectives. But you can basically say it is the notion of true independent thought. Independent thought means you are no longer reacting to a situation. Instead, you contemplate it, you ask yourself questions about that situation, you are then prompted to think more, you collect information, you try solutions or responses to better understand the situation – and not necessarily solve it. Basically, you “explore” the situation. No matter the culture you come from, it was likely heavily influenced by someone (and others) like this. History has many such people who thought for themselves and then laid foundations for others to work with. Adam Smith. Confucius. Mohammad. Aristotle. Francis Bacon. Karl Marx. Buddha. Imhotep. Jesus. Deganawida. There are many more. There would also be others you know who also have independent thought – but they have just not been as influential. You too want to be such a person so your engineering, while potentially being influenced by your background, is not controlled by it. When you can think independently:
So how do you become the type of engineer who thinks independently?
A note for managers – demanding a design log and regular reviews can have the desired effect upon any hip shooters in your team. Or: who can be most easily replaced with A.I.?I would like to first share the anecdote of what led to me writing this article.
Some time back, I started following a newsletter on LinkedIn that was written by a software engineer. We had a number of interactions within the comments section of a few posts – so I sent a connection request. After his acceptance and after reading some more of my content his message to me was “You seem to have a background in real engineering.” He was wondering if my content was equally applicable to software engineering. I had always assumed two things:
I therefore had planned, since then, to write this article – explain that yes software engineers are indeed real engineers and how they too can benefit from things like framing, systemic thinking, and first principles. However, now seems a more opportune time to talk about this nuance of engineering identity. This is because of the mass layoffs we are seeing in the software space due to AI. This trend and how it affects people in the space – people like software engineers – was reported in the L.A. Times (https://www.latimes.com/business/story/2026-03-06/tech-layoffs-pile-up-as-sllicon-valley-shakeout-continues-into-2026). There is certainly some cynicism about this – the term “A.I. washing” is used, but it is also clear that more and more jobs in the space have been automated. Does this automation mean that software engineers were never really engineers in the first place? I recall when CAD became a thing. Many drafters lost their jobs – some of these people were engineers. Some engineers were then expected to do their own drafting or do their own drafting faster – so fewer engineers were needed. I also recall the introduction of simulation software. Engineers did not need to calculate or experiment as much. Again, more could be expected of fewer engineers, and a company did not need as many engineers. However, something else also happened. A company could now consider investing in engineers (or more engineers) because there could now be greater returns. Putting 50% more into your engineers could now see 200% more gains in product improvement – and market share or profit margins. A.I., in the software space, I think, will have the same effect. Applications that once seemed marginal, due to the effort required to develop them, now would seem profitable – because fewer software engineers would be needed to develop the application. Also, larger applications, with even greater returns, can now be considered. Therefore, the recent events in the software space – while deeply troubling for those who have lost their employment (and I do hope that if you are one of these people, then you find something else soon) – is an indication that software engineers are indeed real engineers. They are going through what the rest of us went through some time back. But we can also look more deeply at what software engineers do and compare it to engineering expertise. Do software engineers ever frame? Only all the time. It is often the case that the assumed strategy to create a desired function in an application hit a stumbling block, and a new approach is needed. Also, once the feature is tried with real life users, it is found that the way people actually want to use the application is different from what is assumed. This demands a new approach or frame. Do software engineers need to think systemically? Do I even need to answer this? Applications need to run on something – often a diversity of machines – so this needs to be factored in. Some applications have numerous subroutines – these can interact with each other and cause numerous issues if not managed at the systems level. Most applications also run on machines that are running other applications – and you need to ensure they are compatible. Do software engineers need to use first principles? I recall talking with a software engineer who was writing code for a simulation package. He needed to understand the differential equations – so he needed to understand first principles. However, once the program ran, he did not know if the results were reasonable or not. So he needed to improve his first principles. First principles also helps a software engineer optimise the efficiency of the methods used to process information. This is all congruent with software engineers needing and using first principles. After reading the above, and seeing how the experiences and attributes are so similar, it should be clear to you that software engineers are indeed “real engineers”. I would not be surprised if they are sometimes separated from other engineers, and would benefit more from interactions with other engineers, but it still remains clear that they are engineers and they can be global engineers. Or: Getting all the insights from an engineering teamThere are two types of people in this world – yes, only two.
Those who have their ideas while sitting on the toilet and those who have their ideas in the shower. It is in one of these times of solitude and contemplation that they ponder things in their life and insights that have grown deep inside the unconscious psyche burst into the conscious mind. It is painfully rare for anyone to be in the shower or on the toilet during any kind of review or brainstorming session. And even if they were, these sessions are group activities so there is no solitude – is it more the solitude than the place that is important. For this reason, you are not likely to get all possible insights from an engineering team in any kind of group session. Be it a design review, a scoping activity, a brainstorming session, a risk analysis activity, basically, any activity where you want as many insights as possible to ensure long-term success. If you are like me, then you have likely had that annoying experience where you think you have considered all issues and perspectives, documented them, assessed them, and then determined a path forward, only to have one or two people come to you with more ideas, issues, or perspectives. You appreciate that they are sharing these, but it is still annoying that they come to you after you have done all this work. You feel like you are going in circles and making no progress as you get dragged back each time. You might even decide to ignore them simply so you can progress – even if it is not the most optimised path you are taking. The other thing that might occur to you is that while these are the extra ideas that are shared, there could well be other ideas that were had by people who don’t want to bother anyone – given the work that has been done. It really would have been good to have these ideas presented earlier. So what to do? Factor this into the related activities. Don’t ever assume any brainstorming session, design review, scoping party, gemba walk, risk assessment, or anything else like that will be done in a single sitting. Book one session, run it, give people a break – long enough to have been in the shower or on the toilet – say a couple of days – then have another session. That way, you can be more sure you have conducted an exhaustive, yet not exhausting, consideration. Don’t have time for such an approach? Then simply accept you will not cover everything, and proceed at risk. Best to factor these extra steps into your plans though. Or: How engineers trick themselves without knowing itIn this article I am going to talk about a fault many engineers are cursed with, but, by definition, should not be. It is also a fault that can be exacerbated in a global context so it is even more important for global engineers.
If you want to ensure you are not cursed with this fault, then read on. The curse I talk of is using indicators as opposed to facts to make your engineering decisions. Each word above makes sense to you, I am sure; and the sentence likely seems sensible enough as well. But I will use 4 examples I have experienced personally to make it clearer to you. Caulking glue for precise location control This was an interaction between two engineers who needed to find an adhesive to:
The winner was an adhesive used in domestic applications, was cheap and came in a big caulking tube like one you would see on construction sites. The other engineer, upon seeing the winning adhesive expressed surprise and apprehension. They were expecting something that would come in small containers, like you would see in a laboratory, require mixing, and be expensive. The other engineer, given the scientific rigour used to select the winning adhesive, should have checked their bias. But they did not, they actually let this bias continue to guide them. Metal putty or metal augmented two-part epoxy matrix When a company was looking for a way to adhere a part to an assembly for quick experimental assessment, one engineer used metal putty. If you do not know what this is, then it is basically a glue (a two-part glue) with a high concentration of metal whiskers added. These whiskers make it much stronger than ordinary two-part glue. And, once mixed, it is mouldable like a putty. So you can work it into any shape you like – ideal for experiments when you want to explore different geometries. The experiment worked, but others had issues trusting the results. Why? Because of the word “putty”. It just sounded so agricultural or domestic to them. I know this is the case because they actually said this. If it had been called “Metal Augmented Two-Part Epoxy Matrix” or “MAT-PEX”, then they probably would have been more accepting of the results. Of course, you know, when you think about it, that the name should have no influence on the rigour of the experiment or the results at all. Old textbooks When new editions of a textbook are published, it usually involves a few extra sections based on feedback from lecturers, the use of different units, case studies that seem more recent, or maybe to leverage new learning technologies. The fundamentals will not change. Nevertheless, I have had cases where people thought they would not learn as well because they had an older textbook. This was not because of the difficulty cross-referencing reading tasks allocated for their studies. It was simply because the book looked old. Assuming they could read Latin, such people would look at an original copy of Newton’s Philosophiæ Naturalis Principia Mathematica and assume, because it is so old, that it had nothing useful on the laws of motion. University education Does it matter where you studied engineering? Do you think you are taught different fundamentals at different universities? Do some say “now, everyone, keep this quiet – the real formula is F = m a2!”? The answers to the above in order are: no, no, no. What is more important are things like: how you studied, and the specific educators and the assignments they set. Nevertheless, people will, at times like when they are employing engineers, think the place of study will reflect someone’s engineering knowledge and engineering skill. This is at its worst when people assume foreign universities offer less applicable education – without even knowing anything about those universities. I have mentioned in a prior issue the best way to select an engineer when employing – and it had nothing to do with the place of study. The common theme and the lesson for the global engineer You can likely induce from the above that the general issue at play is an emotional bias based on perceptions that are not questioned – as opposed to the use of facts and logic. The last example is likely the most applicable to the global engineer – for practical reasons – but, as you move from one place to another, the use of logic over instinct, bias and intuition becomes even more important. So, do you tend to judge based on feelings or logic? When you read the above examples, can you imagine yourself making those same mistakes or would you look at the unadulterated facts? Or: Standard procedure, karma, and costThis is the next article in the culture check series. The previous ones looked at Western and Sino backgrounds. This time, I am focusing on an Indian background.
As before, this about recognising tendencies that can arise from a cultural, philosophical, and economic environments. You might recognise yourself in parts of this – I have a Bangladeshi colleague who describes his home country as an Islamic nation with a Hindu culture. You might recognise colleagues – depending upon where you work. Or you might see none of it at all. The point is awareness so that we can grow as engineers. And, as with the other articles, I am focusing on potential limitations. Engineers like problems to solve. There are three aspects I will consider: the perennial caste system, fatalism, and economics. Caste and the idea of “the right way” and staying in your lane The caste system, while officially dismantled and certainly less rigid than in centuries past, has had a long and deep influence on Indian society. It organised life around inherited roles. If you were born into a particular group, there were expectations about what you would do for the rest of your life to make an income. It is wise to note that there were reasons such systems existed. One benefit often overlooked is environmental continuity. If your family and descendants were going to fish the same waters for generations, you had every incentive not to overfish and protect those waters from others. Long-term role continuity can create long-term stewardship – there is a reason this land was able to support so many people. I am not defending the system; I do not care for it, personally, but it did not arise without logic. But there were not just expectations about what you would do within your caste. There would often be implicit understandings about how it would be done. This would be handed down from one generation to the next because it was established that it would maintain the balance of things. It could also dictate what you should not do – to make it clear which caste you are in. Often, discussions about the caste systems focus on organisational and social mobility. That is not my focus here. There is plenty written elsewhere about promotion, opportunity, and structural reform. What I am interested in is something more subtle. When a society has long embedded the idea that roles come with prescribed practices, it can create a strong psychological tendency toward standard procedure. In engineering, this can show up as a preference for:
But engineering excellence is not the same as procedural compliance. If your background encourages the belief that there is a correct, inherited way of doing things, you may be less inclined to reframe a problem. You may ask, “What is the standard process here?” before asking, “Is this the right problem?” That is a subtle but important difference. Framing is about questioning the boundaries and assumptions. It is about asking whether the standard process even applies in this context. A cultural leaning toward prescribed practice can sometimes make that reframing instinct weaker. Still, when translated into engineering, the “there is a way” mindset can become a constraint. Then there is the issue of being a sensual engineer. I have spoken before about the benefits of experiencing the physical aspects of a problem. Touching the thing that is of consideration, listening to it, taking it apart yourself and putting it back together. In the caste system, for many who become engineers, this physically and be an anathema to one’s caste. Thus, the caste system can sometimes limit the experience and perception an engineer will have of an engineering challenge. Karma, fatalism, and first principles Another influence often associated with Indian culture is the idea of karma. Whether one believes in it literally or not, when you grow up in an environment where ideas of fate, destiny, and moral causation are frequently discussed, it can subtly shape perspective. One possible tendency is fatalism. If something does not work, it may be interpreted as “not meant to be.” If a project fails, there can be a sense that forces beyond control were at play. Even without conscious belief, this ambient perspective can influence how problems are approached. In engineering, this can weaken first principles thinking. First principles require you to assume that outcomes are governed by natural laws. If something failed, it failed because of identifiable causes. If something works, it works because of physical relationships. There is no moral dimension. There is no destiny. There is only cause and effect. A fatalistic undercurrent can reduce the instinct to dig back to fundamentals. It can encourage trial and acceptance rather than analysis and derivation. Further, it can result in acceptance of how things are – for oneself and others. This is not what engineers are meant to do. They should always be thinking of ways to make thing better for all. There is, however, another side to this. Karma can also be interpreted as personal responsibility and perseverance. If you are being tested, you might iterate relentlessly. You might refine and adjust repeatedly to prove worth. In that sense, the same philosophical environment can produce extraordinary persistence. Developing economy and the power of jugaad India has developed rapidly, but it remains shaped by decades of operating under resource constraints. From that environment has emerged something widely recognised and even celebrated: jugaad. As described in Jugaad Innovation by Navi Radjou and his co-authors, jugaad refers to frugal, improvised innovation. It is the art of making things work under severe constraints. The classic example is the missed call. You ring someone a predetermined number of times and hang up before the call connects. They see the missed call from you with the set number of rings, and they know to meet you at the station. No cost incurred. Communication achieved. That is ingenuity. From an engineering perspective, growing up in an environment where cost sensitivity is constant can create a powerful instinct to optimise for affordability. You become highly alert to waste. You find alternative paths. You adapt quickly. This is an advantage. However, constant adaptation can also create inconsistency. Engineering systems often rely on repeatability, traceability, and disciplined configuration control. If ad hoc cost-saving improvisation becomes habitual, systemic robustness can suffer. Systemic thinking requires you to ask not just, “Does this work now?” but, “What are the long-term interactions across the whole system?” Jugaad can sometimes prioritise immediate functionality over systemic integrity. What does this mean for you? If you are from an Indian cultural background, then ask yourself:
That is what makes someone not just a local engineer, but a global one. Or – learn the secret language of engineeringWhen going for a job, engineers know they can do that exact job. They know they do it well. They would not have applied otherwise. But when it comes to explaining why they can do the job (be it in their resume, their cover letter or the interview), the message does not always get across.
So the job goes to someone else – likely someone who previously had a job that was almost the same (that’s the go-to-move used by many employers). You have probably experienced the above yourself. In the previous article, The Need for Willpower, I talked about how frustrating it can be to have strong global engineering skills while working for people who are certain they know better. I also said I would explain how you can use these to better explain yourself when going for a job. So let’s talk about that now. For graduates: proving you understand engineering, not just exams Graduate engineers often look identical on paper. Same degree. Same subjects. Same grades. What interviewers are really trying to determine is whether you understand engineering, or whether you simply learned how to pass engineering exams. This is where noting framing, first principles, and systemic thinking can give you the edge. Point to any example you can and explain:
Design projects or any work experience during study are best here. They are often the closest thing students experience to real engineering practice: incomplete information, competing constraints, trade-offs, and uncertainty. If you have access to design projects — especially open-ended ones — leverage them heavily. For example: “At first I thought this was a materials problem, but after reframing it as a thermal–mechanical interaction, the constraints became obvious…” or: “Rather than relying on testing, which would be time consuming, I went back to first principles to inform my decision. I found that…” and: “I didn’t want to simply assume what was presented. I considered the broader system for opportunities or risk and found that I could…” Statements like this tell an interviewer something very important: you weren’t just executing procedures — you were thinking like an engineer. Experienced engineers: making expertise transferable For experienced and senior engineers, the challenge changes. At this level, employers aren’t just evaluating what you’ve done. They’re trying to work out whether your capability is locked to a specific industry, organisation, or economic environment — or whether it travels. This is where global engineering fundamentals really matter. Instead of listing achievements, you explain how you think:
“It should be noted that I was not following standard procedure. They’re engineering fundamentals applicable to all industries. Industries like [INDUSTRY YOU ARE APPLYING TO]. That’s why they apply even when the context changes.” This is especially important if you’re moving between industries, organisations at different levels of maturity, or regions with very different economic backgrounds. Engineering does not exist in a vacuum — constraints, incentives, and decision-making are shaped by economic reality just as much as by culture or structure. Being able to articulate that awareness signals depth. Engineering managers: scaling judgment across people and contexts For engineering managers — engineering leads, heads of R&D, CTOs — the emphasis shifts again. At this level, you’re no longer just applying framing, first principles, and systemic thinking yourself. You’re developing them in others. Strong candidates for these roles can clearly explain:
A manager who understands that framing, systems, and first principles manifest differently depending on context is far better equipped to guide teams. Not by imposing answers, but by shaping how problems are understood in the first place. What’s more, the fact that you know what the attributes are of the expert engineer will likely separate you from other would-be managers. You show that you are indeed an expert engineer – as expected of a manager – as well as having the required leadership attributes. A powerful combination you should articulate. Why this works: labels make thinking visible A lot of engineers already do these things. But they just don’t label them – making it hard for other to understand or see your ability. When you say:
I’ve used this approach myself repeatedly when applying for roles. I link all the actions I mentioned to an attribute of engineering expertise. And without fail, people switch on. They understand what I did and how significant it was because I gave it a name and explained the meaning. If you’ve read my book, you’ll know there are many other attributes worth developing — fixation, attachment, goal analysis, and more — particularly for leadership roles. But framing, first principles, and systemic thinking are the core. They are the fastest way to make your engineering capability legible. And once it’s legible, it becomes employable. Also, if your application involves moving countries, working across cultures, or managing international teams, one book I strongly recommend is The Culture Map. It provides a practical framework for understanding how communication, authority, and decision-making vary globally — all of which directly affect engineering work. Start mentioning these things in your next application. And all the best with that application too – along with all the others that follow. I hope your engineering career continues to be onward and upward – offering you all you wanted from it. Or, Why it’s hard when you’re good |
