While I hold a number of certifications included Lean Enterprise Design and a Six Sigma Black Belt, I have found more often than not the simplest tools yield the best results.
During my career, I have had the opportunity to visit numerous suppliers and internal facilities to help resolve issues or challenges.
Too often companies I visit, believe the complex tools of six sigma will save them. While it's true they can make a difference if applied properly, unfortunately in my experience most companies apply them incorrectly.
The tools are challenging to learn and even more difficult to apply.
This is why I start every engagement in front of a whiteboard. Not only does this play to my strengths but it helps the organization "see" the problem in front of them. Once you can visualize the problem fixing it becomes much easier.
I'm at home in front a whiteboard. If want to get the best out of me and your organization give me a whiteboard and a problem to solve. We'll both be better off because of it.
