I published my first book back in 2009. Grounded in my passed experience with Agile software development (during the last ten years), I give a taxonomy of implementation pitfalls and discuss, what one can do about it.
Unfortunately the book is only published in German. As of today the book is out of print.
If you are interested you can still order it (used copies) here.
My new book will be titled "Disillusoned by Agile? - From Pain to Progress: Diagnose and Alleviate Agile Dysfunction". It is a revised, update and expanded version of my previous book. As the context for Agile organizations has changed over the years and many people seem to be disillusioned by Agile approaches, I changed the title for the new English version.
