Related questions: Can we use upstream models directly in implementations? What is the interest of the Logical Aspect if I want to build an SOA? We put important efforts in upstream aspects, can we make some savings in the logical one? The logical aspect is sometimes considered useless and we hear some people willing to [...]
Related questions: How to find them? How to assert that they are the right ones? How to respect the decoupling principle? By giving clear procedures to deduce services from business inputs, Praxeme solves the problem of finding the right services in the only available way: changing intuition only procedures to analytic thinking. By structuring precisely [...]
We see more and more attention on relations between SOA and other parts of IT, with important questions like the one raised in the following blog post: http://www.jpmorgenthal.com/morgenthal/?p=103. Relations between SOA and BPM is like relations between bass guitar and drums. They live separately and have their own rules, but they can produce great music [...]
Often people ask me why I don’t like the use of DNA and other biological markers as identities. My answer can be expressed in two points: Biometric data cannot be repudiated. If your biometrics are compromised you cannot change them like you can do when your personal certificate (or password) is compromised. Biometric data are [...]

We often hear that people do not follow rules because they do not understand risks and Schneier shows us that the error is to forget that we do not live in a world [...]
[Part 1] Here are some points to focus on to try to get out of the immaturity model. Some are obvious. Some may sound like weird ideas. But do not underestimate culture: obvious points may not be obvious for everyone and weird things may well be weird only for those who see them for the [...]
“IT is a young discipline” syndrome For as long as I have worked in IT I have heard this dogmatic explanation. It is used for all sorts of issues ranging from hardware failures to heavily bugged software including huge and astonishingly complex IT solutions without strong relations with business problems. Each time, the maturity idea [...]
This is just a quick note about a dreadful news: IT business is running short of trigrams. Trigrams are those nasty special words made of the three capital letters of some difficult to understand expression we traditionally use to attract interests in a new Graal. Running short of such beasts is a nightmar because without [...]
Lately I re-read a list of errors about computers [fr+en] (sorry for English readers, items are in English but comments are in French) found in movies. It’s not exactly the first time I’ve read such a list and it’s always amusing to see a collection of problems movie makers do about our domain, but this [...]
