Why would we think of SG as a “risk risk management” process? management • All models have a similar approach, All see Table 10-1. see Six Sigma Six • Description on page 214 is poor. • There are two main programs: There SS Improvement and DFSS. SS • Credit for SS goes to Motorola Credit and GE though most of the material was “borrowed” from from the TQM and design methodology communities. methodology Fundamental Concept Fundamental mean -6σ +6σ Six Sigma Improvement Six Define Measure Analyze Improve Control } { Plan Do Check Act Refinement of TQM’s Deming Cycle, focused on improving processes.
