Talk:Managing groups for high performance
Text Clarity; Ok.
Since you reference PMI, look if this standard has any definition of group or/and team, if not find these definitions and compare them group vs. team, investigate if projects are developed by groups or teams and based in this research change or not the title of your article. You still missing more specific references regarding your topic.
In general the abstract is ok, nice that you already established the structure of the article, how ever you still missing the annotated bibliography and reference sections, hat you have under your note section are references.
Just a reminder, Annotated bibliography is a list of articles, books or documents followed by a briefly descriptive and evaluative paragraph.
When developing the article don't forget to elaborate and describe the relevance for a Project Manager.
