Structured Innovation is about doings things differently and doing things significantly better.

In this sense, Shainin fits that description very well. It’s a structured problem solving method that combines engineering insight with statistical thinking to solve tough technical problems quickly and efficiently.

I specialize in providing problem solving expertise to solve urgent, critical and chronic manufacturing and technical problems.

Earlier in my career, I also worked as Master Black Belt and Shainin Red X Master for seven years with Delphi Corporation and General Motors, where I trained teams to solve chronic technical problems.

Shainin also combines the Y to X approach with "talking-to-the parts" technique by forcing the parts to reveal the insights and clues to the nature of the problem.

As you know, most tough problems often involve interactions that are not yet understood or recognized through experience alone.Clue generation tools such as Component Search, Group Comparison, Pair Comparison are used to converge on the Red X. W confirmation test is then used to confirm the Red X.Tolerance Parallelogram is used to set the proper tolerance. Several years ago, I was involved in a brake leaks case.I work as a Director for SSA & Company (formerly Six Sigma Academy). I work with deployment teams to achieve process improvements through consulting, training, project execution and change management.I train, coach and mentor Black Belts Master Black Belts, and Champions using Lean Six Sigma to solve problems.Today’s busy Process Excellence professionals need solutions to their process improvement problems not in weeks or months, but in days. In this Six Sigma IQ interview, Ha Dao, Director for SSA & Company (formerly Six Sigma Academy), explains how the Shainin methodology can be leveraged for more efficient and quicker problem solving.Please talk a bit about your Process Excellence background.I have worked with many clients in which Shainin problem solving skills allows the Green Belts or Black Belts to find and eradicate root causes of problem faster with fewer resources.Shainin is particularly powerful in the Analyze phase of the Six Sigma DMAIC.Pre-Control is used to keep the problem under control. Take me through a brief case study to show how someone can employ some of these basic tools. This is when you are driving down the road, step on the brakes and nothing happens. Shainin was used to solve this huge brake leaks; we called it a "spill" on a drum brake application of a major automotive original manufacturer (OEM).This leak problem was causing the OEM to hold vehicle shipments and required very expensive and time consuming repair at the end of the production line.
