Lean Software Development and IfSQ

The term Lean Software Development originated in a book by the same name, written by Mary Poppendieck and Tom Poppendieck. The book presents the traditional Lean principles in a modified form, as well as a set of 22 tools and compares the tools to agile practices. Mary and Tom's involvement in the Agile software development community, including talks at several Agile conferences has resulted in such concepts being more widely accepted within the Agile community.
