Abstract: The purpose of this paper is to explore a Six Sigma implementation that combines quality acceptance with business performance using the Q × A = E model and questionnaire survey method. The paper begins with a review of the literature on Six Sigma and its key factors, followed by a theoretical framework that is developed via an empirical study of a Taiwanese firm. The results of the Six Sigma measurement system proposed in this paper show that each organisation has a unique management position when initiating a Six Sigma project. The Q × A = E model can be used to obtain valuable insights about Six Sigma implementations and firms should be able to achieve better management decisions after conducting self-assessments using the model.

Keywords: six sigma; quality management; quality culture; aerospace industry; Taiwan; self-assessment.
