Shainin uses a radically different approach which is called the Y to X (or Effect to Cause) to converge on the root cause.

Shainin uses a radically different approach which is called the Y to X (or Effect to Cause) to converge on the root cause.This is a huge paradigm shift of the traditional approach of X to Y, which is listing of potential causes (Xs) through brainstorming and engineering judgment then test to see if the Xs have an effect on the Y. Like reverse engineering, it starts out with a well defined effect, Y, which is a measured response that has engineering leverage and reveals insight into the physics of the failure.

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.

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.

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 also executed and led teams to solve over 100 projects, which together delivered over million in savings.With more than 25 years of experience, I’m certified as a Lean Six Sigma Master Black Belt, Shainin Red X Master and recognized by the American Society for Quality as an ASQ Fellow. How does it fall within the realm of structured innovation, and why would Process Excellence professionals choose to use this method over other process improvement/structured innovation methodologies?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.Prior to joining SSA & Company, I worked as the Manager, Innovation and Continuous Improvement Methodology (I&CIM) for Delphi Corporation.In this position, I provided leadership to deploy Lean Six Sigma, Design for Six Sigma (DFSS), and Shainin Problem Solving for billion multi-business units globally.It uses Strategy Diagram to identify most leveraged direction.Isoplot is then used to make sure the measurement system is effective.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.
