Le Praxeme Institute respecte quelques principes forts dans ses travaux et Praxeme est l’expression même de ces principes. Au coeur de notre reflexion est la rigueur. Certains pourront trouver à redire à cette ambition qui peut être perçue comme désuète et old fashion. Ce serait oublier que nos systèmes aujourd’hui sont souvent au point de [...]
Masters of Disaster Here is a very enlightening paper from Wharton’s Risk Management and Decision Processes Center: http://www.whartonmagazine.com/issues/815.php IT projects fall in the same behavior: Quote: “a psychological bias toward short-term maximization instead of long-term planning—a psychological bias all humans share”. IT Project: short ROIs, code before design and architecture, intuition instead of analytical thinking, [...]
See notes at the end of the post Scoping The scoping aspect (also known as politics aspect) is the pre-modeling concern before real modeling efforts of the upstream aspects (semantic, pragmatic and geographic). This is where we gather all raw material from very diverse sources including (but not limited to) enterprise and business strategies, business [...]
Related questions: Why separate Elementary and Set machines/operations? Would it be interesting to add a CRUD Business Logical Machine next to the Elementary and Set ones? It is clear that we are considering things in the Logical Aspect and that no justifications will come from Technical Aspect. First shot CRUD operations are not high level [...]
This is a follow-up to a conversation that started during the meeting of the “Collège des contributeurs” last week. Although I do not have the time to post a proper discussion, I’ll start with a few headlines to “get the ball rolling” : start a discussion. Hence I’ll use an “outine style” and leave the [...]
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 [...]
Here is an interesting point of view on security business today from an IBM Security Strategist: http://www.networkworld.com/news/2009/081709-8-dirty-secrets-of-the.html Among the eight points some are tightly related to enterprise strategy and enterprise architecture. Points 2, 6 and 7 focus on external concerns, regulations and security product vendors, but others may be summarized like this: what do I [...]
In 1999 when I joined an Open Source community to port a software on VMS systems, this essay was a must reading for all Open Source fans. It represented some kind of a first description of methods used in Open Source groups. At this time Open Source was seen as parallel system for software editing [...]
