Red X® problem solving is a highly structured and disciplined system for finding the hidden causes that are keeping systems (either manufacturing processes or products) from performing properly. It is particularly effective at revealing higher order interactions (3, 4 or 5 factors).

Red X flips the typical problem solving model. Our approach allows you to converge only on what matters by focusing on the effect rather than guessing at causes. It’s a strategic process of elimination using the physics of product, the process design and what we call ‘contrast’.

offers the system under the trademarked name Red X® Strategy. Much of SS is neither well documented, nor adequately discussed in peer-reviewed journals. The goal of this article is to provide an overview of SS, a critical assessment, and a brief comparison with other industrial problem solving systems.

We will focus on three methodologies: Six Sigma (Lean Six Sigma), Shainin RedX® strategy and Kepner-Tregoe problem management. Six Sigma was originally developed by Motorola in 1985 as the set of the tools for process improvement.

Shainin projects are evidence based; converging on the largest source of variation, the Red X. For a Shainin project, the underlining principle is DY = f(Dx).

Understand captures the relationship between the source of the problem and the system output and establishes a tolerance on the Red X that accounts for the range of product performance that will result in customer enthusiasm and the variation coming from all other system factors.

May 2, 2005 · What is it - Red X is the GM accepted problem solving methodology that uses engineering skills, common sense and simple statistics to solve technical problems with statistical confidence. Heart of Methodology: Red X, Green Y, Best of …

two principles: The Red X principle and Y X™ Thinking. The Red X principle was discovered by Dorian in 1947. It recognizes that the contributions to system. one cause-effect relationship is dominant. This recognition refutes Walter Shewhart’s belief that once a. The Red X principle deals with a natural phenomenon.

Oct 12, 2024 · The fundamental premise of the Shainin Red X® process is that for any problem, there is a dominant root cause that must be eliminated or mitigated for the process to be improved. In this article, we will define the Red X process, best practices, and how it can be applied to your organization.
