Way back in 1969, as a kid, I watched a very interesting movie - "2001: A Space Odyssey."

Defining Requirements – The TOGAF Way

If you are new to TOGAF, you may be wondering how this process is different from what you do in a typical “Requirement Analysis” phase of software development. Once I tell you that the many of the techniques recommended in TOGAF are what you are already using, like UML modeling techniques like Activity Models, Use-Case Models and Class Models, you may think why bother with TOGAF? What you really do differently in TOGAF is that you take a much wider perspective of the requirement. There are three important things that you need to do: Explicitly document the current state, the ex... (more)

TOGAF – Preparation Aid for Part 2

The questions for the Part 2 Examination consist of eight complex scenario questions. You need to read a scenario describing a situation where TOGAF is being applied.

There is one correct answer, two partially correct answers and one incorrect answer for the situation. The correct answer scores five points, the second best answer three points, and the third best answer one point. The incorrect answer scores zero points. The pass mark is 60%. The eight scenarios ar... (more)
