Building Culture for Continual Improvement

In this book, Nanda shares his experiences in the form of real-world cases that illustrate opportunities for manufacturers to gain more from their implementations of SPC. Each of his experiences serves as a launching pad for further discussion. Some readers will see their organizations in these examples. Some will even see themselves.

Client testimonials

My team was able to confidently implement SPC. Nanda’s unique ability to create interest in SPC is commendable.

– Mr. Thomas Mathew, Plant Head

“IDMS eliminated need for paper based PMC charts. Dr. Selva and team from PQSI did a good job in transferring the ownership to shopfloor.”

– Dr. S Rajkumar Swaminathan, President

We decided to use GAGEpack software for calibration management in all our plants in the world. PQSI team’s suggestion to use concurrent license was cost effective.
