Using Theory of Constraints to Accelerate Lean Six Sigma

Theory of Constraints (TOC) can give us insights into how to accelerate Lean Six Sigma and get results in a day. Here’s how:

“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified” and QI Macros [software].

“You know, I’ve been around Quality for almost 30 years now; 30 years exactly, almost. If I think about it, it’s super cool… but why is it so slow and so unsticky? Why is it taking so long for it to get everywhere? I’ve come up with some theories about that.
