My understanding is that this Summary, along with the majority of the Business Case, should be developed by the Executive role.
I have been requested to produce an Executive Summary since I will manage the project but I lack the understanding of what the project is actually trying to achieve. The Executive Manager in this case has set up this project as a Business Process Improvement by using SharePoint but hasn't given me any direction so I cannot determine when we will be able to consider that the improvement has been reached.
I am not sure if this Executive Summary is meant to be part of our Business Case or if it's just a document to inform Senior Management of our plans. Anyhow I would like to make sure whose responsibility is this to approach the right person.
As PM have you ever had to produce these Summaries? What other roles' support have you used?
