I found creating personas to be quite challenging. So I looked around the web for other resources that might make it clearer or at least give a different perspective. I found one article by Lene Nielsen. The article gave 10 steps to use when creating usability personas. Please find the link below
I found this article to be helpful because it list steps to help guide you in developing your personas. I thought Cooper (Chapter 5 p 77 did a great job with this also. This article gives a different perspective of the step by step process for developing effective personas. One part that I found interesting in the article as opposed to Cooper is the verification step. This is where you find data to support your persona descriptions and scenarios. This made sense because when creating personas, you use the data collected to help get an idea of what your users are like. But is what you came up with correct? Or make sense? Even though article seems to be focus more on development as oppose to the “user”; I think you can pull different techniques and ideas from each process (Cooper and the article).
