Currently I am reading the book titled "Agile Software Development" by Alistair Cockburn.
The Indian Version of the book is available in FisrtAndSecond.com site.
The book is a must for people interested in Agile Methodologies.
Some more good books on Agile Methodologies from Amazon –
- Agile Software Development, Principles, Patterns, and Practices by Robert C. Martin
- Agile Software Development with SCRUM by Ken Schwaber and Mike Beedle
Agile and Iterative Development: A Manager’s Guide by Craig Larman
