The following references will provide a very nice overview of the field – from general theory to in-depth case studies:

1) Six Sigma: The Breakthrough Management Strategy Revolutionizing the World’s Top Corporations by Mikel J. Harry, Ph.D. and Richard Schroeder, Doubleday 2000.

2) Six Sigma Leadership Handbook by Rath and Strong Staff, John Wiley & Sons 2003.
