# Critique (2) on Theoretical Paper

Author: Weiyong Zhang & Xiaobo Xu
Title of article: Six Sigma and Information Systems Project Management: A Revised Theoretical Model
Publication Project Management Journal (2008), Vol. 39, No. 3, 59–74

Summary: The paper focuses on how Six Sigma best practices can be fused into IS project management and can result into quality and success of IS projects i.e. how Six Sigma can impact IS projects positively.

To validate this, the author adopted a theory development approach by taking an existing model called R&R model by Ravichandran and Rai (2000) to develop a revised theoretical model that represents an improvement on the model to have what is termed a quality-oriented model. Here, the three basic aspects of R&R model (domain, constructs and relationships between constructs) are re-examined in the context of Six Sigma.

The author in supporting its research, reviewed the three views of IS project management, the quality-oriented organisational system approach to IS project management and then Six Sigma in terms of relevance to IS project management.

The author also mentions the limitation of the research which are:

• That the revised model should be taken as first step to fussing Six sigma to IS project management
• That the revised model is only applicable to IS projects and not any other type of projects

A: Quality of the Research

B: The Research Method

C: Quality of Presentation
