Out of the Crisis:
by
W. Edwards Deming
A classic but not an easy book to read. Packed with good ideas that still have great merit. New paperback printing (2000).
The New Economics: For Industry, Government, Education
by
W. Edwards Deming
Second Edition (reprint). The best of Deming's books for learning about his system for management. Packed with great thoughts but not as easy to read as the best books. This is a great book, but often it is best for managers already committed to finding new ideas.
