Great book for how to implement and achieve improvements. Helps us get on our way of answering the 3 Questions.
1. What do you want to do, improve, accomplish?
2. By what method? or how will we reach what is desired
3. How will you know? helps us understand how to measure to determine if have made improvements.
I recommend you read this along with getting more familiar with the work of Dr. W. Edwards Deming.
