It is our pleasure to present the second edition of this book. The first edition was released couple of years back. Since then we wanted to add several things to enable revision of BABOK more meaningful and quicker. So, here we are.Our objective to write this book was to create a concise revision guide for Business Analysis Body of Knowledge (BABOK) guide v3.0. BABOK is a big book with around five hundred pages and revising BABOK can be cumbersome. So, how does it help you in revising? One of the proven revision approaches is to create notes. We conceptualized this revision guide as notes. So, the first edition was written as notes based on BABOK. It simply summarized BABOK v3 and was much smaller than BABOK. However, we wanted to make it more meaningful for all the readers. So, we have now added concept notes, mock questions, crosswords, and matchmaking. We have also added examples at the end of Techniques chapter. The examples are added to help you see the real-life usage of the technique. It is added for selected techniques. The guide is meant for professionals who are planning to undertake ECBA certification examination. This revision guide covers these BABOK chapters - key concepts, all the six Knowledge Areas, Perspectives, and all the 50 Techniques.For the best results, this revision guide must be picked up after you have gone through the BABOK guide once. You will find all the key aspects of BABOK in this guide. This means that you do not need to pick up BABOK again.Cheers and all the best for your exam!Abhishek SrivastavaAmit Lingarchani
