Xingxing Zu , Lawrence D. Fredendall , Thomas J. DouglasJournal of Operations Management

Introduction

There is a criticism that Six Sigma simply puts traditional quality management practices in a new package.

This study reviewed both the traditional quality management and Six Sigma literatures and identified three new practices that are critical for implementing Six Sigma’s concept and method in an organization.

A research model and survey instrument were developed to investigate how these Six Sigma practices integrate with seven traditional quality management practices to affect quality performance and business performance.

Six Sigma role structure Six Sigma uses a group of improvement specialists, typically

referred to as champions, master black belts, black belts, and green belts (Henderson and Evans, 2000; Linderman et al., 2003).

Six Sigma structured improvement procedure Six Sigma applies a structured approach to managing

improvement activities, which is represented by Define–Measure–Analyze–Improve–Control (DMAIC) used in process improvement or Define–Measure–Analyze–Design–Verify (DMADV) used in product/service design improvement (Linderman et al., 2003).

Six Sigma focus on metrics Six Sigma metrics are used to set improvement goals

(Linderman et al., 2003; Pande et al., 2002).
