Article Abstract

[This abstract is based on the authors' abstract.] The Shainin System™ (SS) is a problem-solving system and its associated strategies and tools developed by Dorian Shainin. Shainin's consulting firm offers the system, also referred to as Statistical Engineering, under the trademarked name Red X® Strategy. Although widely used and promoted in manufacturing, SS is not well documented or discussed in the literature. An overview of SS is given in addition to a critical assessment and a comparison with other industrial problem-solving methods. The focus of the discussion is the guiding philosophy and principles of SS. The assessment finds that while many elements of SS are valuable and should be incorporated into other process improvement methodologies, many of its statistical tools and methods are neither unique nor necessarily superior to other available resources.
