Purpose

Given the critical role of project prioritization and selection process in Six Sigma efforts, this study aims to analyse the relevant literature to answer this question: What types of project prioritization and selection methods have been used in Six Sigma research?

Design/methodology/approach

The study implemented the systematic literature review (SLR) method to identify and review all relevant previous studies.

Findings

The study revealed that 59 articles focused on the topic used 111 methods, analytic hierarchy process appeared as the most frequently used method with 12 articles (20%) and one-third of the methods used in the current Six Sigma project selection literature contained multi-criteria decision-making methods. In total, 61% of 59 articles were not published in the journals ranked by the ABDC’s list. Only 17% of the articles reviewed in this study were published in journals ranked as B category and 12% of the articles were published in A category journals.

Practical implications

The findings of this literature review may help Six Sigma practitioners and researchers accurately identify project prioritization and selection methods, considering that qualitative and quantitative scientific methods guarantee to make better decisions than “gut feelings” of the decision makers in this process.

Originality/value

Although a variety of studies focused on the topic, an SLR is lacking in the area of Six Sigma project prioritization and selection. Therefore, this study was constructed using the SLR method to analyse the topic.

6 sigma 项目优先排序和选择方法：系统文献回顾

目的

鉴于项目优先级和选择过程在六西格码工作中的关键作用，本研究旨在分析相关文献以回答这个问题：六西格码研究中使用了哪些类型的项目优先级和选择方法？

设计/方法/方法

该研究采用系统文献回顾 (SLR) 方法来识别和回顾所有相关的先前研究。

发现

研究表明，59 篇文章集中在该主题上，使用了 111 种方法，层次分析法是最常用的方法，有 12 篇文章（20%），目前 6 Sigma 项目选择文献中使用的方法中有三分之一包含多标准决策方法。总共有 59 篇文章中有 61% 未在 ABDC 列表排名的期刊上发表。本研究审查的文章中只有 17% 发表在 B 类期刊上，12% 的文章发表在 A 类期刊上。

实际影响

考虑到定性和定量的科学方法可以保证在此过程中做出比决策者的“直觉”更好的决策，本文献综述的结果可能有助于 6 Sigma 从业者和研究人员准确确定项目优先级和选择方法。

原创性/价值

尽管各种研究都集中在该主题上，但在 6 Sigma 项目优先级和选择领域缺乏 SLR。因此，本研究采用 SLR 方法构建，对主题进行分析。
