Joining me today for Episode #384 of the podcast is Craig Gygi, co-author of the book Six Sigma for Dummies. He also managing principal and owner of the firm Strategic Productivity. You can read his full bio there. He also has an online course called “Truth About Data” which covers statistical process control for business metrics, as I have written about.
So, we have that shared interest in data, statistical methods, and problem solving even if he comes at it from a Six Sigma perspective (starting from his days at Motorola) and me from a Lean perspective.
Craig's previous leadership roles include:
- COO, Purple
- Executive VP of Operations, MasterControl
- Director Operational Excellence, Fiji Water
I hope you enjoy the conversation like I did. You can listen to the audio or watch the video, below.
