I decided to compile a list of books that have been useful to me, as a business analyst.

Some of these books are designed to be a reference to help you in your job, some of them to help with specific BA qualification and some just to read and retain. I have placed the books in order of importance and influence to my knowledge as a Business Analyst:

* Business Analysis - Don Yeates, Debra Paul, Tony Jenkins, Keith Hindle (Paperback – Apr 21, 2006)
This is the main text for the BA Diploma and I think the first and main text to concentrate on as a BA.
* CBAP Certified Business Analysis Professional All-in-One Exam Guide with CDROM - Joseph Phillips (Hardcover – Aug 1, 2009)
So far, the first book covering the CBAP syllabus.
