I had waited for this book since mid 2010 when I contacted the publisher to find out when the English version would be available, and although a little light in volume [147 pages] it is informative and to the point. So no waffle about what the author thinks or their own 'stories'/ experiences on the subject, which a lot of authors of technical manuals sometimes tend to do. I am a test professional and want to firm up my understanding in areas of Business Analysis/Requirements Eng and intend to take the CPRE Found. exam so this is perfect. In fact, sad as it sounds, I couldn't put it down and had read half of it before I realised. It flows, logically, through the requirements process and underpins the basics for a succesful grasp of the discipline. And although an essential read for the CPRE exam, it is a very handy reference manual, especially when as a tester I want to instill in colleagues the importance of good quality requirements. It does what it says on the tin and explains the processes involved for a good grounding in Requirments gathering. I think this is an essential bookshelf item for any BA/PM/Test Man/Analyst. A handy reference manual and an interesting, easy read. Well worth the wait and the money.
