Donald J. Wheeler, PhD is a world-renowned expert in continuous improvement. He's worked with W. Edwards Deming and wrote the classic book Understanding Variation.
Wheeler once wrote and said, "Statistical Process Control is, at its heart, about getting the most from your processes. It is about the continual improvement of processes and outcomes. And it is, first and foremost, a way of thinking... with some tools attached."
I’d like to thank him for providing the perfect quote for a blog about process control charts because measurement, control, and improvement are exactly what they are designed to enable.
