Lean Six Sigma Implementations by GPOE
Byrne, Lubowe, and Blitz refer to innovation driven by Lean and Six Sigma combined. Indeed, at GP's Operational Excellence practice (GPOE), we increasingly teach both Lean and Six Sigma philosophy and tools. Our Green Belt certification consists of two weeks of training, four days per week, separated by two to six weeks, plus one completed DMAIC project and successful completion of a test. The Green Belt Project begins during the first week, and we encourage each project to be through the Define Phase and into the Measure Phase before the second week begins. We also recommend that selected projects can be completed within 120 days.
To begin Black Belt certification, students must complete Green Belt Certification. Then they spend two weeks of training, five days per week, separated by two to six weeks; plus an additional DMAIC project and successful completion of a test. An additional project begins during the first week of Black Belt training and we encourage each project to be through the Define Phase and into the Measure Phase before the second week begins. Black Belt projects may take longer to complete than Green Belt projects. There is currently no industry standard Lean Six Sigma exam and certification; however, GP provides certification of successful completion of the course, project, and test, provides a summarization of the body of knowledge covered.
When compared to Six Sigma training and certification, adding training in Lean tools necessitates reducing training on Six Sigma or adding training time. Our curriculum reduces training on some advanced Six Sigma tools. Specifically we provide an introduction to non-normal distributions and design of experiments, but not experience. However we do integrate easy-to-use general statistical and also DOE software into our training.
We almost always are called upon to supplement the classroom training experience with project coaching. Coaching is vital for reinforcing the training. This localized support is essential to ensure, as Byrne et. al. point out, that your organization is equipped to make radical innovations, and maintain this approach over time. Because the commitment of your organization is the single most important ingredient in any LSS effort.
