Six Sigma has been gaining momentum in industry; however, academics have conducted little research on this emerging phenomenon. Understanding Six Sigma first requires providing a conceptual definition and identifying an underlying theory. In this paper we use the grounded theory approach and the scant literature available to propose an initial definition and theory of Six Sigma. Our research argues that although the tools and techniques in Six Sigma are strikingly similar to prior approaches to quality management, it provides an organizational structure not previously seen. This emergent structure for quality management helps organizations more rigorously control process improvement activities, while at the same time creating a context that enables problem exploration between disparate organizational members. Although Six Sigma provides benefits over prior approaches to quality management, it also creates new challenges for researchers and practitioners. 相似文献

Six Sigma: The role of goals in improvement teams 总被引:1,自引:2,他引:1
Kevin Linderman Roger G. Schroeder Adrian S. Choo 《Journal of Operations Management》2006,24(6):779-AND
The tenets of goal theory have been well established as a motivation mechanism in the management literature. However, some quality-management advocates, such as W. Edwards Deming, often criticize the use of goals. This research investigates the tension between goals and quality management in the Six Sigma context. We find empirical support that goals can be effective in Six Sigma improvement teams when teams adhere to the Six Sigma tools and method. However, challenging goals are counterproductive when Six Sigma teams do not use the tools and methods rigorously. This research reconciles the differences between quality management and goal theory by showing that the Six Sigma tools and method interact with goals. 相似文献

Organizational practices related to Six Sigma are believed to have resulted in improved organizational outcomes. The academic
community, however, continues to lack understanding of the constructs and causal relationships underlying Six Sigma. Hence,
discussion of Six Sigma is buffeted by anecdotal experience reported from practice. We evaluate Six Sigma through the lens
of literature on theory development to explain why the Six Sigma constructs, assumptions, and causal relationships are inconsistent
with theory development principles.

Previous information systems (IS) research has significantly improved the success rate of IS projects, but the result is still far from satisfying. The effort to advance IS project management theories continues. One notable effort is Ravichandran and Rai (2000). Based on quality management principles, they developed a model (the R&R model) describing a qualityoriented organizational system that leads to software development quality performance. This study analyzed Six Sigma to propose major revisions to the R&R model. Six Sigma is a recent approach to quality management with proven effectiveness. The analysis of Six Sigma suggested that several constructs in the R&R model need to be respecified, leading to the definition of a new quality‐oriented organizational system. More importantly, the revised model posits that the new organizational system leads to IS project success that can be measured by organizational performance improvement. This study contributes to the literature and provides practical guidance to IS project managers. 相似文献

基于六西格玛流程改进的库存管理优化 总被引:1,自引:0,他引:1
库存管理是企业用来控制实际库存问题的方法,主要帮助企业经营者确定何时补充订货、补充订货多少以及安全库存等问题。现有的库存控制研究往往只关注数学建模阶段的精确性,而对库存波动根源认识不足,导致数学模型越来越复杂、完善,但库存仍然居高不下、难以控制。本文针对该问题,提出了在库存管理中糅合六西格玛管理理念的思想,通过六西格玛方法揭示库存积压的根源,从源头着手,进行流程改进,从而达到库存优化、提高客户满意度的目的。文章通过实际案例证实了基于六西格玛理念的库存优化管理的有效性。 相似文献

Six Sigma has already become an efficient improvement technique adopted by a great number of enterprises. Numbers of Sigma
has become a tool of measuring process capability in some enterprises. But some of enterprises still use process capability
indices (PCIs) to measure the process capability. So numbers of Sigma and PCIs both can be used to measure the process capability.
The paper will research the relationship between PCIs and numbers of Sigma. In bilateral specifications, the paper will research
the relationship between the PCIs which are Cp, Cpk, Cpm and Cpmk, Spk and numbers of Sigma. In unilateral specifications, the paper will research the relationship between the PCIs which are Cpu and Cpl and numbers of Sigma. If supplier and buyer use different tools to measure the process capability, then the communion bridge
to Six Sigma and PCIs can decrease the communicate noise. 相似文献

Green Lean Six Sigma has been recently clarified to improve the environmental sustainability performance of operations, but it seems glaringly scarce and in need of cutting-edge studies to integrate the concepts of green, lean, and Six Sigma into one unified application. This paper is accordingly aimed at constituting the application of Green Lean Six Sigma as a cleaner production. In doing so, a Define, Measure, Analyze, Improve, and Control (DMAIC)-based approach that is one of Six Sigma's well-known methods was proposed to systematize a Green Lean tool—environmental value stream mapping. Thus, this paper as one of the preliminary studies aligns environmental value stream mapping with DMAIC through presenting the proposed methodological approach, which relies on the five DMAIC phases—Define, Measure, Analyze, Improve, and Control—and considers green wastes in each phase simultaneously. To support the narrow body of knowledge, this proposed approach was validated via the action research-oriented case study implemented in the substrate manufacturing system that seeks to develop the environmental sustainability of its production processes and subsequently its general competitiveness. The findings indicated the effectiveness of a DMAIC-based approach in systematizing environmental value stream mapping and improving its efficacy to achieve environmental sustainability. The case analysis revealed that the application can significantly lessen the consumption of chemicals and energy in the system by 28% and 21%, respectively. 相似文献
