Quality Improvement Methods for Identification and Solving of Large and Complex Problems
ثبت نشده
چکیده
This article is analyzing three methodologies used for identification and resolving of large and complex quality problems: Six Sigma, Shainin and KepnerTregoe problem management. To compare these three methodologies the general quality improvement roadmap was defined consisting of 5 phases: Problem definition, Diagnosis, Generation and selection of solutions, Enhancement and New routines. The aim of comparison was to identify whether the methodologies, methods and tools can supplement each other. This would allow to work on quality improvement within one general problem solving pattern. The Six Sigma as the most generic methodology can serve as the base to develop such pattern while DMAIC roadmap can be used as the backbone.
