Lean Software Development Books

Books on Lean software development:

Three books from Mary and Tom Poppendieck. I enjoyed reading all 3 of them.

1) Lean Software Development: An Agile Toolkit by Mary Poppendieck and Tom Poppendieck

2) Implementing Lean Software Development: From Concept to Cash by Mary Poppendieck and Tom Poppendieck

3) Leading Lean Software Development: Results Are not the Point by Mary Poppendieck and Tom Poppendieck
