Purpose

Lean Six Sigma (LSS) is receiving a tremendous attention as a modern process of streaming to improve the organizational ability and customer satisfaction. A successful LSS implementation is influenced by various factors and the execution of all the influencing factors simultaneously is a very difficult task for any organization. From the perspective of limitation of resources, this paper aims to present a basic issue in an LSS implementation of clustering complex and impacting factors into groups to achieve them in a stepwise manner. This paper aims to present a fundamental issue of clustering the complex and impacting factors of an LSS implementation into groups to achieve them stepwise.

Design/methodology/approach

A total of 40 relevant influencing factors toward an LSS implementation have been identified from the extensive literature review and duly validated with experts’ opinions. Integrated fuzzy set theory and decision-making trial and evaluation laboratory (DEMATEL) approach are demonstrated to explore the causal relationships among influencing factors of the LSS implementation. An empirical case analysis of an Indian manufacturing organization is carried out to illustrate the utilization of the proposed model.

Findings

The proposed framework effectively finds out the significance of each influencing factor of an LSS implementation and clustered into cause–effect groups. As per the results of the empirical case analysis, ten critical success factors (CSFs) of the LSS implementation are evaluated for the successful LSS implementation. Top management pays more attention to achieve them and implement them in a phase-wise approach under the limitations of accessible resources.

Research limitations/implications

The presented framework provides an effective, precise and systematic decision support tool for recognizing CSFs of the LSS implementation. The organization, decision-makers, industrial practitioners and academic researchers may be able to comprehend the cause–effect relationship of the influencing factors of the LSS implementation. The exploratory nature and the single case study are two major limitations of this analysis. The developed model is heavily dependent on the experts’ opinions; hence, any bias in judgment will influence the final result.

Originality/value

This analysis is the first of its kind of effort, according to the best of the authors’ knowledge, to classify the influencing factors of LSS implementation into the cause–effect cluster. The outcomes of this analysis make the complexity of a problem easier in handling and assisting the decision-making.

分析影响精益六西格码实施的关键成功因素：模糊DEMATEL方法

目的

精益六西格码（LSS）作为一种现代流媒体处理流程正在得到极大的关注，以提高组织能力和客户满意度。LSS的成功实施受到多种因素的影响，同时，所有影响因素的执行对于任何组织而言都是一项艰巨的任务。从资源限制的角度出发，本文旨在提出一个将复杂因素和影响因素聚类成组以逐步实现它们的LSS实现的基本问题。本文旨在提出一个基本问题，即将LSS实现的复杂因素和影响因素聚类为小组，以逐步实现它们。

设计/方法/方法

从广泛的文献综述中，总共确定了40个与LSS实施相关的影响因素，并得到专家意见的充分验证。结合模糊集理论和决策试验与评估实验室（DEMATEL）方法，论证了LSS实施的影响因素之间的因果关系。进行了一个印度制造组织的经验案例分析，以说明所提出模型的利用。

发现

所提出的框架有效地发现了LSS实施的每个影响因素的重要性，并归结为因果组。根据经验案例分析的结果，对LSS实施的十个关键成功因素（CSF）进行了评估，以评估LSS的成功实施。高层管理人员更加注重实现这些目标，并在可访问资源的限制下以分阶段的方式实施它们。

研究局限/意义

提出的框架为识别CSF的LSS实施提供了有效，精确和系统的决策支持工具。组织，决策者，行业从业人员和学术研究人员也许能够理解LSS实施的影响因素的因果关系。探索性和单个案例研究是此分析的两个主要限制。开发的模型在很大程度上取决于专家的意见。因此，任何判断上的偏差都会影响最终结果。

创意/价值

根据作者的知识，这种分析是其努力的第一步，它将LSS实施的影响因素归类为因果群集。分析的结果使问题的复杂性更易于处理和协助决策。
