Glad you asked...
Collect all the information that is of central meaning for the project. Then start with the scope of the project, having in mind all the gains and expenditures, all the main points which result in achievements or fails. These fails have to be fixed so the project analysis should also include results and solutions.
Then again, this answer might help you...
In writing a project analysis, the scope of the project should be considered, as well as the costs and the final expected results should be included.
