BABOK. A Guide to Business Analysis Body of Knowledge.
This book doesn’t need an additional review, because people form business analysis are already known about the whole content from the book, but maybe not every one of the people acknowledges the importance of it and can truly estimate benefits from BABOK. People who are not a BA or not from relative to business analysis work, don`t need this book at all, `cause there are a lot of other books which could explain something similar to BABOK but in more `lightweight` way.
As for me, this book is a part of my preparation for CCBA certification, so I couldn`t avoid BABOK))
But at the very end, I can reassure every BA(especially a beginner BA) that you need to read it at least once, but no sooner than 1.5-2 work experience.
When I tried it my first time(it was after 1 year of work) this book looked like a disaster for me. But by read it now I really liked it.
