Benefits, obstacles, and future of six sigma approach

Abstract

Understanding the key features, obstacles, and shortcomings of the six sigma method allows organizations to better support their strategic directions, and increasing needs for coaching, mentoring, and training. It also provides opportunities to better implement six sigma projects. This paper examines the evolution, benefits, and challenges of six sigma practices and identifies the key factors influencing successful six sigma project implementations. It integrates the lessons learned from successful six sigma projects and considers further improvements to the six sigma approach. Effective six sigma principles and practices will succeed by refining the organizational culture continuously. Cultural changes require time and commitment before they are strongly implanted into the organization. © 2004 Elsevier Ltd. All rights reserved.
