Breaking the 5-Sigma Barrier with SystemsEngineering

摘要

Many organizations have successfully implemented Six Sigma (6σ) quality programs,rnbut have begun to hit what they call the 5-sigma barrier ? they have discovered that you canrnonly get so much quality improvement from the back end of the development process. Tornovercome this 5-sigma barrier, organizations are increasingly adopting the Design for Six Sigmarn(DFSS) methodology that in many ways reflects the "systematics" of product development. Thisrnpaper examines the Six Sigma and DFSS approach and how DFSS in essence is a "StatisticalrnSystems Engineering" approach that can achieve six-sigma levels and beyond in productrndevelopment.
