Critical Chain is the original business novel about Critical Chain Project Management, written by Eli Goldratt.  It does a good job of building up the case for CCPM and describing the impact this new way of thinking can have.

P3CG recommendation:We recommend Critical Chain for anyone who is getting into Theory of Constraints for project management.

Simplifying Innovation: Doubling speed to market and new product profits – with your existing resources by Mike Dalton is an excellent business novel about an organization struggling to grow by developing new products quickly and manufacture them as well.  The book is enjoyable to read and makes for a number of “ah-hah” moments.  Recommended.
