Lean Six Sigma Bursts

We share our takes and thoughts on a variety of topics related to process improvement (specifically Lean and Six Sigma methods), Bursts are rapid improvement activities, so this sounded like a good word to use for these short audio clips. We’ll try to keep them under 5 minutes each.

In this episode, I discuss a project I’m really excited about, the 2nd book release in the Lean Six Sigma for Good book series.

This is the 2nd collection of real-life experiences and stories from Lean and Six Sigma practitioners who have spent time at the “gemba” with not-for-profit organizations. They have generously offered to write a chapter about lessons learned and tools they have applied. There are 8 chapters in total.
