engineering leverage and reveals insight into the physics of the failure. 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. By asking clever questions of the best and worst examples, the cause driving the

differences is revealed in the answers.

During the progressive search investigation, each stage is divided into natural buckets or splits of causes. By leveraging the contrasts, these buckets

are progressively eliminated to converge on the dominant cause, which is called the Red X. Combining Y to X strategy and talking to the parts

technique provides a very powerful problem solving strategy.

How may Shainin be used to help complement other structured innovation/process improvement methodologies such as Lean Six Sigma?

Shainin can be used to complement the Lean Six Sigma methodology. 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. Shainin finds the root cause extremely fast, most of the times in days instead of weeks or months. Shainin can take

your Lean Six Sigma program to the next level!

What are some of the most basic tools that Shainin employs?

Let me describe some of the basic tools as they occur in the problem solving process.

Shainin uses the Problem Definition Tree to convert business problems to high-value projects. Then it uses Project Definition Tree to convert a project

to a well defined Y or response with engineering leverage. It uses Strategy Diagram to identify most leveraged direction. Isoplot is then used to make

sure the measurement system is effective. Clue generation tools such as Component Search, Group Comparison, Pair Comparison are used to

converge on the Red X. B vs. W confirmation test is then used to confirm the Red X. Tolerance Parallelogram is used to set the proper tolerance. Pre-

Control is used to keep the problem under control. These are some of the basic tools.

Take me through a brief case study to show how someone can employ some of these basic tools. How did you get to the root cause of the

problem? What was the end result?

Several years ago, I was involved in a brake leaks case. This is when you are driving down the road, step on the brakes and nothing happens. Its not

a good thing.

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. Using the Shainin Y to X approach, progressive search and talk-to-the-parts investigative technique, the Red X was quickly found to be surface

imperfection of the sealing interface which was causing the leaks. The Red X was confirmed with statistical confidence and controlled within a few

days, allowing the plant to resume normal productions. Savings and cost avoidance exceeded one million dollars annually. This is a typical case study

where a tough project is solved very quickly.

How can a company get started with using Shainin? What sort of training is involved with mastering Shainin?

You can get the Shainin skills through training, coaching and project work. Shainin offers certification like Six Sigma program. There are three levels of

competency or belts. The first is Apprentice Level (like Green Belt). The second level is Journeyman (like Black Belt). And the highest level is Shainin

Master (like Master Black Belt). Similar to Lean Six Sigma, in addition to the training in the classroom, working on projects and coaching are the major

components of gaining the Shainin skills.

What are the key takeaways of Shainin that Process Excellence professionals should share with their companies?

Shainin is complimentary with Six Sigma programs and Lean initiatives. Shainin supports the customer focus, data driven project-based improvements

and senior leadership engagement found in all successful performance improvement programs. Shainin will take problem solving to the next level,finding the root cause much faster and with fewer resources.

As a Lean Six Sigma Master Black Belt working with many clients, I have seen first hand that Shainin techniques have solved many tough technical

problems in days, not weeks or months. And many problems were deemed unsolvable. I would encourage Process Excellence professionals to

consider Shainin techniques the next time they face a very tough problem that needs to be solved fast.
