SEA: Systems Enterprise/Engineering Architecture

About the Book

Why am I writing this 'SEA' book at all.

I have long been unhappy with the Enterprise Architecture methods used by IT people internationally. I have taught my ‘Architecture Engineering’ classes for several years

Selling the certifications, for such poorly crafted architecture methods, is a shame, shared by the agile certification game. These methods are an insult to common sense that says we must take qualities and costs far more seriously in real and large systems. Why are so many people fooled?

The core problem as I see it is that the methods taught and used are no longer good enough for the large scale, complex, changing technology. The central idea that is missing is quantification (of all values, qualities and costs).

Without this tool, too many bad decisions, and costly ones will be made. Quantification is the distinction between arts and crafts on the one hand, and engineering, science, good management, logic, traceability, responsibility on the other hand.

The problem is not new. There comes a threshold of complexity in all disciplines where quantification becomes a necessary tool. The time has come for IT Enterprise

Architecture to really make use of quantification, and not just talk about doing it.

I have written many books about this subject, and they are in the references. But they have not influenced EA so it is time to write a book aimed directly at EA culture, so they have no excuses, that this is some other discipline.

This is probably a hopeless case. The only time things will change is when management will only hire and employ people who can serve their organizations interests better, by being more like engineers. Anyway this is my contribution.

Let me be clear that my objective is to change poor practices. So I would be pleased if anybody would like to copy the ideas in this book in whole or part. The ideas are free. But if any reader wants to commercialize the ideas, in methods packages, training, consulting, apps, so that they are spread effectively. That is welcome. I provide a recipe, you can bake the cakes. Nice if you credit sources, I do, but I won’t sue you for forgetting.

About the Author

Tom Gilb
Tom Gilb

Tom Gilb has been consulting on management problems, for top management since 1962.  As a result he has developed and refined his own powerful methods for management planning. He has worked for many of these years with his son Kai Gilb. 

These methods are jointly called ‘Planguage’ – a Planning Language. They are unique in helping managers to think quantitatively about the qualitative aspects of their decisions. For example how to quantify ‘engineering productivity’, or general product quality?

Most of the consultancy work is done at the CTO level. Most of it is for technical multinationals, and some financial groups. Most of the work is for planning organizational improvement in productivity and quality (for 10,000 engineers for example). The rest is about big projects (like 1,000 engineers, $100 million).

Tom does not profile himself as a management consultant. In fact he  works at the grass roots of advanced engineering, systems, software, aircraft, IT, telecoms, electronics. 

This often leads to meeting top managers who appreciate his methods, and become clients. There is a well-documented successful spread of his methods at HP, IBM (CMM 4) and Intel (20,000 engineers trained there in his methods). Other interesting famous method-user organizations are Boeing, Citigroup, JP Morgan, Credit Suisse, Philips,  Ericsson, Nokia, Tata Consultancy, Microsoft, Equinor and many others, smaller and less famous.

Tom has been invited to lecture at dozens of  universities worldwide (including Berkeley, Stanford, London School of Economics, Imperial College). 

He has previously published nine paper books. The 2005 book is ‘Competitive Engineering’.  

He has spent 2 years  (2014-2015) working on his new book ‘Value Planning’, especially for top managers. Published initially on LeanPub 2016.

In 2018-2021 He produced about 20+ books digitally. Most at Leanpub, or Gilb.com

In 2020, long course length videos were made by Oslo Software Architecture (OSWA), based on the SEA Systems Enterprise Architecture book https://www.youtube.com/channel/UCb508f8y_d0PqRZKPCVVVxQ,

And many long videos about the books were made by BCS SPA SG such as https://www.youtube.com/watch?v=qaBhijqVWYA for the Sustainability Planning book.

and many other of my book videos are below this one on that site.

In 2012 he was made Honorary Fellow of the British Computer Society.

He lives in Norway and London, and is both Norwegian (as of December 2015) and US Citizen (1940).
