Chapter Chapter 1 in Six Sigma for Organizational Excellence, 2015, pp 1-18 from Springer

Abstract: Abstract Six Sigma is a disciplined problem-solving method involving people management and stakeholder participation. The approach relies heavily on advanced statistical methods that complement the process and product knowledge to reduce variation in processes. Six Sigma as a quality improvement tool advocates the practice of measuring variability of a process, which may then be controlled by continuous improvement. We have critically examined various quality perceptions and definitions. The ultimate objective of Six Sigma philosophy is to deliver the expected customer satisfaction in a given time frame without harming the organizational environment. Many implementation tools including DMAIC, DMADV, DFSS, and kaizen are discussed in details. Apart from the above tools, some of the tools used in DMADV that are not covered in DMAIC are as follows: multi-generational project plans (MGPP), analytical hierarchy process (AHP), Kano analysis, KANSEI Engineering, TRIZ, Pugh analysis, Taguchi optimization, Capability Maturity Model Integration (CMMI), value stream mapping (VSM), and simulation methods. The chapter is organized as per the tasks and deliverables of Six Sigma. A brief discussion about the belt systems is also presented in this chapter.
