Purpose

This paper aims to develop an initial understanding of the Lean Six Sigma methodology since its inception and examine the few Lean Six Sigma dimensions as a research domain through a critical review of the literature.

Design/methodology/approach

The paper is structured in two-part. The first part of the paper attempts to dwell on the evolution of the Lean Philosophy and Six Sigma methodology individually and the emergence of Lean Six Sigma methodology, covered under the Lean Six Sigma: a historical outline section. The second part of the study examines the dimensions associated with Lean Six Sigma such as frameworks, critical success factors, critical failure factors, type of industry, performance metric, year, publisher and journal, based on a total of 223 articles published in 72 reputed journals from the year 2000 to 2019 as a literature review.

Findings

The adoption of Lean Six Sigma, as a continuous improvement methodology, has grown enormously in the manufacturing and few service sectors such as health care and higher education during the past decade. The study revealed that researchers came out with conceptual frameworks for the implementation of Lean Six Sigma, whereas the validation through case studies seems to be lacking. The integration of Lean Six Sigma and other approaches with a focus on sustainability and the environment has emerged as a research field. A few of the most common critical success and failure factors were identified from the articles studied during the study.

Research limitations/implications

This paper may not have included some of the studies due to the inaccessibility and selection criteria followed for the study.

Originality/value

This paper will provide an initial introduction on Lean, Six Sigma and Lean Six Sigma and research insights Lean Six Sigma to beginners such as students, researchers and entry-level professionals.

精益六西格码方法文献的批判性审查

目的

本文旨在初步了解精益六西格码方法论，并通过对文献的批判性审查，将少数精益六西格码维度作为一个研究领域进行研究。

设计/方法/方法

论文分为两部分。本文的第一部分试图分别详述精益哲学和六西格码方法论的演变以及精益六西格码方法的出现，涵盖在精益六西格码：历史大纲部分。该研究的第二部分研究了与精益六西格码相关的维度，例如框架、关键成功因素、关键失败因素、行业类型、绩效指标、年份、出版商和期刊，基于在 72 家知名杂志上发表的总共 223 篇文章。 2000 年至 2019 年的期刊作为文献综述。

发现

在过去十年中，精益六西格码作为一种持续改进方法的采用在制造业和少数服务行业（如医疗保健和高等教育）中得到了极大的发展。该研究表明，研究人员提出了实施精益六西格码的概念框架，但似乎缺乏通过案例研究的验证。精益六西格码与其他关注可持续性和环境的方法的整合已成为一个研究领域。从研究期间研究的文章中确定了一些最常见的关键成功和失败因素。

研究限制/影响

由于研究的不可访问性和选择标准，本文可能没有包括一些研究。

原创性/价值

本文将为学生、研究人员和入门级专业人士等初学者提供关于精益、六西格码和精益六西格码的初步介绍以及精益六西格码的研究见解。
