My guest for Episode #264 is a friend from here in the Dallas / Fort Worth area, Tyrone Butler. He is LSS Managing Partner at his company, Butler Active Business Solutions LLC. He has a background in the Air Force, he pre-dated me at Dell Computer in the 1990s, and he’s being doing a lot of work all over the world with Lean, Six Sigma, and other methodologies for improving software and project delivery, like ITIL. Tyrone is one of the first to hold the “Certified Executive Master Black Belt (CEMBB)” certification through Mikel J. Harry, PhD. We first met probably back in 2010 when we were both part of a Lean group that went to visit the Toyota plant in San Antonio (which I blogged about here and here). In this episode, he’ll share some of his experiences, including a presentation to Michael Dell, his thoughts on the combination of Lean and Six Sigma, and methods that he has seen work in software development and other settings.
