A great honour…

I was surprised and honoured to learn that I have been selected as a finalist in the professions category for West Australian of the Year: http://www.celebratewa.com.au/2018-finalists/professions-award-finalists/.

I have to say thank you to those who nominated me first and the judging panel.  I also need to thank everyone who has been part of my life and the projects which were cited in the award and so many others too.  Thank you to all the Close Comfort team and so many customers who have bought our products.  Many good people at UWA, particularly in the engineering and mathematical sciences faculty, deserve recognition for all the help and support they have provided.  Thank you to my family and so many other people who have helped and supported me for so long.

Just one thing, since I have your attention.  We in Australia are so fortunate, a vast and richly endowed continent, with so many wonderful energetic people who care about the world.  We can help others build a better future for all.  I feel so fortunate that I have been able to help with ideas and inventions that could improve life for everyone,  especially those suffering from heat and inadequate drinking water.  Our future depends on how we help the least fortunate, everywhere, and at the same time help build a better world for our children and grandchildren.  There are lots of ways to help: please do what you can, either yourself or by supporting people who can make a difference.


Engineers: I need your help

I have taken on the job of editing a short book – 30 Second Engineering being published by Ivy Press.  The aim is to provide non-engineers with a quick introduction to what engineering is all about.

The book is part of a widely published, popular series and is likely to be translated into many languages.

Part of the challenge is to describe everything about engineering a non-engineer might want to know in 50 paragraphs of 220 words, each encapsulating a separate engineering topic!

Here’s a draft for mechatronics, just to give you an idea of the content we are aiming for.

I need your help with suggestions for famous engineers to be featured in the book, particularly engineers from Asian or other countries and not so well known in the English-speaking world.

Energy Savers Cooling a Warming World

You probably know that I now spend most of my time running our little technology startup company Close Comfort.   We recently passed a significant milestone with over 1000 of our energy-saving air conditioners sold to happy customers.

It all started with my marriage to wonderful wife and partner Samina Yasmeen.  Living with her Pakistan family brought summer reality.

Two billion people South Asia dread the summer. Shimmering heat starts in March and April and stifling sweaty nights last into November.  Listless days follow nights of fitful sleep at 40C under noisy fans. A tiny privileged elite run energy guzzling split air conditioners, crippling electricity grids.

Load shedding, a novelty in Australia, is routine across south Asia and Africa: power is on and off every hour or two.  Batteries keep fans and LED lights on but the unit electricity cost soars.

Sustainable relief from heat and humidity is now in sight thanks to our energy-saving air conditioning technology.   It’s a great thrill that our air conditioners are now in 5 countries, albeit with small-scale marketing campaigns.

Guide for Value Creation in the Engineering Enterprise (Updated March 4, 2018)

  • Engineers’ remuneration and recognition is strongly related to the value they create – a well-supporting finding in economics.
  • Our research shows that engineers today know little about value creation, and what little they do know does not align well with investors’ ideas.
  • We conclude therefore that engineers will be paid less than they think they are worth (which agrees with survey findings) and second, there is plenty of potential to improve engineers’ remuneration and recognition if they take the time to learn how to create value.

The Great Artificial Intelligence Scam (Again)

{A longer version of this post appeared in the Australian Financial Review on August 18th under the title “When robots learn to lie, then we worry about AI“.}

Great claims are being made for artificial intelligence these days: AI.

Amazon’s Alexa, Google’s assistant, Apple’s Siri: these are all claimed as examples of AI.  Yet speech recognition is hardly new: we have seen steady improvements in software like Dragon for 20 years.

We have seen claims that AI with new breakthroughs like ‘deep learning’ could displace 2 million or more Australian workers from their jobs by 2030.

I was fortunate to discuss artificial intelligence with a philosopher, Julius Kovesi, in the 1970s as I led the team that eventually developed sheep shearing robots.  With great insight, he argued that robots, in essence, were built on similar principles to common toilet cisterns and were nothing more than simple automatons.  “Show me a robot that deliberately tells you a lie to manipulate your behaviour, and then I will accept you have artificial intelligence!” he exclaimed.

That’s the last thing we wanted in a sheep shearing robot, of course.

Address to North America – Tunisia Engineers Group July 28, Monastir, Tunisia

In this address, I talked about the differences in engineering practice between Paris and Tunis and how young Tunisian engineers can learn to be experts by understanding how they can contribute economic, commercial and social value from their work.

Here is an audio recording (apologies for the noise and low quality)

And the powerpoint presentation


Bill Williams and I have now written a book chapter and a journal article about these ideas, but it will still be several months before they appear.  If you would like advance copies of these manuscripts, please write to us.

Tunis has some wonderfully picturesque locations, particularly at Sidi Bou Said, where the traditional architecture and streetscape was preserved by orders of the French Protectorate.

I visited the ancient Carthage port and ruins of the citadel…

Leftover “spare parts” fascinated me: these exquisite marble columns represented the technological state of the art at the time of the Roman occupation.

At Al Jem, there is a vast, wonderfully restored Roman amphitheatre which serves as a reminder of Tunisia’s past engineering achievements, albeit under Roman tutelage.

With our guide Lotfi Hassine and companion Dr. Vasundara V Varadan, who delivered an inspiring keynote address on Saturday.

Some other photos:

Note the notches used with lifting clamps to ensure no stones would be dropped while being lifted into place.

Here are some of the enthusiastic young engineers I met and had the privilege to work with at Monastir.

Dr Ammar Kouki, Chair of NATEG 2017, and Dr. Ahmed Khebir, volunteer their time and energy every year to organize NATEG for up to 600 young Tunisian student engineers.

Finally we were entertained by the Central chapter of the Tunisia America Chamber of Commerce in Sousse – a memorable evening.

Missing the obvious

Sometimes a research result is so obvious that you miss it.  That’s why researchers collaborate: there is less chance of overlooking the obvious.

Bill Williams and I have written about engineering value creation: how most engineers create value even though they don’t necessarily invent anything new or do designs.

And we both managed to miss something obvious.  Engineers create value when they educate others.  In my book, The Making of an Expert Engineer, chapter 8, I wrote about the ways that engineers teach others (and also learn from others, often at the same time).  This teaching and learning activity is more extensive than many engineering students might expect.

Engineers are often said to build things, make cars, planes, phones and so on.  But they don’t.  Other people do, however, with the help and guidance of engineers.  So engineers spend the largest single chunk of their time on technical coordination (chapter 9), informally influencing and leading others.  Across all the engineers we have observed, they spend 25-30% of their time on that: gaining the willing and conscientious collaboration of others who contribute time, effort, knowledge and skills within an agreed time frame.

Why so much time?

In essence, engineers accumulate technical knowledge and understanding and use that to align the actions of all the other people who contribute their performances sufficiently closely with technical intentions that the investors who provide the money will walk away sufficiently satisfied, enough of the time, so they come back and do it all again for something new.  Repeat business in other words.

And that means that engineers spend much of their time explaining why things have to happen a certain way.  And explain this in different English or other dialects so that all the other actors, ranging from investors to contractors to suppliers to government regulators and local communities learn enough to collaborate effectively.

And that’s not all the teaching.

Much of the teaching performed by engineers cannot be attributed to a specific coordination effort.  One of the most obvious examples is teaching younger engineers, helping them learn in the workplace, passing on knowledge and technical insights.  Studies (e.g. Bailey & Barley 2010) have shown that younger engineers need up to an hour a day of one-on-one guidance and teaching in the workplace, and much of that is performed by more experienced engineers.

Now, one of the most interesting findings from our research with Australian firms comes from asking about charge codes for teaching younger engineers.  A simple question “When you are helping to develop the skills of younger engineers in your organization, is there a charge code that you enter for that in your time sheet?”  Almost (but not quite) invariably the answer is “No, I have to do it in my own time, in effect.  It’s just a responsibility that goes with the job, I guess.”

Australian engineering firms, maybe other firms as well, we don’t yet have enough data to be sure, overlook the value of training their own engineers as something that creates value.

Well, we are guilty too.

We overlooked the value created when engineers develop the skills, knowledge and attitudes of others.

We have therefore amended our recent posts and will also have to amend our publications which, fortunately, are still “in press”.

Engineering Value Creation

Before reading this, please see the post of December 7, 2017, where I have released a comprehensive guide for engineers, students and educators on value creation in engineering enterprises…..


In my last post, I wrote a brief explanation about value and value creation, noting that “value” has many different meanings.

In this post I will summarize what Bill Williams and I think is a new theory of engineering value creation, the subject of my address to the International Conference on Engineering Education Research (iCEER 2016) in Sydney on November 24.

Most engineers create both societal and economic value from their work, but without much awareness on how they achieve that.

Interviewing engineers with my students, we noticed how many engineers find it hard to explain how their work creates value, especially engineers who are not designing new products.  At first we were surprised to find that this was no easier for engineers with commerce or MBA degrees.  Later, we realized that this reflects the lack of theoretical understanding about the links between engineering and economics.

Why is this important?  Why does the lack of theory really matter?  Surely it’s obvious.

Well, no, it is not obvious.  And without a theory to explain engineering value creation it hard to teach students why engineering is valuable. Continue reading

Value and Value Creation

The word ‘value’ is challenging for engineers because it has several related meanings.

First the mathematical meaning. ‘Value’ denotes a number associated with a variable, for example x=2.72. It can also denote a numeric value in a spreadsheet cell resulting from calculations.

Next, we speak of “human values”, usually positive or desirable attributes such as honesty, humility and loyalty.

We can also appreciate “value systems” such as a money-oriented system of values, or a religious or humanist system of values that influence human behaviour. Many organisations espouse their own values, though aligning individual actions can often be problematic.

For this discussion, ‘value’ is a measure of the extent beneficial or useful, often associated with a monetary value. Thus, we talk about the “face value” of a currency note or the “value of a house”.

“Value creation” implies activity that results in something valuable, beneficial or useful. Human values and value systems only arise from long and complex socialisation within a community, and a mathematical values exist through definitions.

Most discussions on value in business centre on the notion of “exchange-value”. This is usually an amount of money exchanged in return for a service, or artefact, or the entitlement to a service or to acquire an artefact at some future time.

The notion of value extends beyond a simple monetary exchange, however.

If we think about the motivation behind a decision to spend money, or to work to gain something, we encounter the pleasurable anticipation of acquiring something valuable. It might be the future entitlement to a service or possession of an object. It could also be gaining peace of mind, a feeling of security, through entitlement to protection from something unpleasant. For example, people pay taxes to their government in return for security: protection against the possibility of destructive behaviour by other people, disease, or loss of their property. Philosophers refer to this notion as “use-value”, the emotional pleasure experience associated with the acquisition.

Value creation, therefore, denotes activity that results in services or artefacts that can be enjoyed by people.

Since this emotional pleasure lies at the root of value creation, “use-value” is subjective: everyone will experience the service or artefact differently, and enjoyment will depend on circumstances. The unpleasant anticipation of feeling thirsty when walking outside on a hot day motivates people to exchange money for bottled water they can carry with them. The apparent “use-value” is heightened if, for example, there are no other water sources or known providers nearby, even though the quality and quantity of water in a bottle is precisely known.

There is another consequence from understanding the emotional basis of value: value creation depends as much on the user as the creator. In other words, value is co-created. For example, the use-value of the bottled water is probably greater if the water slakes one’s thirst on a hot day, than if the water is used to wet some sand in order to create a sand sculpture, or poured onto a shrivelled weed.

The extent to which a person can anticipate a specific pleasure or pain, or understand another person’s second-hand description, also influences use-value.

Finally, a person’s perception of use-value can motivate a decision to buy or sell in exchange for an amount of money, revealing an exchange-value. Since every person sees it differently, with an unconsciously different potential exchange-value, their response in any given situation is unpredictable.

Understanding notions of value creation takes us into the realm of subjective experiences and all the different ways that people anticipate these experiences. Then we can begin to appreciate the various ways that value can be created by engineers for their clients and humanity.

Yes, it’s difficult at first. Many engineers yearn for fixed objective truths, and shy away from fuzzy subjective emotions. However, our research shows that engineers who understand value creation enjoy more respect and far more rewarding careers, both intrinsic enjoyment and financial benefits.

The next post will start revealing how engineers create value through their work.
