I am a Lean Six Sigma Black belt, our company had several of us trained and many more Green Belts as well. I worked on several projects and completed many saving millions of dollars. However, they never really grasped the investment in time it took to develop and sustain the changes we made and we were all given many other tasks and assignments. Eventually, the project work became side work or things worked off the corners of our desks. Basically the department has fizzled out and I no longer even work on projects because I took a promotion to a different area. I do use the tools in my daily work life to some extent but not the entire process. Our manufacturing plants do have dedicated black belts but there is no longer an enterprise effort to have them impact the Logistics side. Being my activities were primarily internal to my company, I do not belong to any organizations.
