Anna: I think you need to be a bit more specific in scoping your article in regards to which method/tool you want to go in depth with.

Reviewer 1, DI2009

Topic; It seems like an interesting topic (method description). However I had a hard time to figure out, whether or not the title matches the content.
Introduction; Due to the missing link between the title and the topic, it would have been nice to get a description of the article. Maybe it could start with: “This article describes how Six Sigma can be used in Project Management…”.
Structure; A structure which gives the reader an overview of the points and states a small conclusion, would help the reader, both catch the readers interest and make it easy for the user to know what the article is about.
Section introduction; a short introduction to each section would help the reader know what to expect.
Text; I believe that the article is not finished and still some more elaboration is missing.
Figures and illustrations; It would be nice with some figures or illustrations to catch the readers interest and help the reader.
Titles; the titles could be more descriptive e.g. “Overview of the article” and “Idea with using Six Sigma” etc. This will also help the reader in what to expect.
Annotated Biography; remember that the references should have a short description
Referencing; I think you should find more academic articles at least if it is possible do not refer to Wikipedia.
