Precision and Accuracy in Measurement

In this first part of a two-part series, I chat with Bill Bellows in this episode. Bill gave us a little history of his introduction to Genichi Taguchi's methods and quality concepts while working as an engineer in the jet engine industry. We explore key ideas around variability reduction, precision vs accuracy, process capability, and Taguchi's loss function. Our conversation looks at the difference between traditional quality approaches focused on specifications and Taguchi's view of quality based on quantifying loss and variation. We riff on analogies using a dartboard and Deming's red bead experiment to clarify Taguchi's perspectives on "loss" and variation even within specification limits. Bill's LinkedIn can be found here:
