Development A Guide To Modern Software Delivery

I found this book to be an excellent reading, the book is very concise and covers a big breadth of subjects and areas. It's one of those books that you can always have close for when you need to search about a subject. Also this book is really good to have has: 1. A checklist for good practices, and to see what you are doing. 2. A Starting point for a subject that you don't know about.
