Without knowing too much about it, I imagine you would need to cast a wider net during the project for stakeholders and risks since invariably the project "scope" may go well beyond the end deliverables to incorporate the social, environmental and even political implications of the project. Appropriate metrics needs to be devised at the end of the project to assess whether or not the product or service of the project was and continues to be successful. I see it as a project within a product/service lifecycle. When the project is done, the PM's job is done. However, they may continue on in some capacity given their experience with the product/service delivered, and best placed to assess and manage ongoing risks and value to the product/service and its stakeholders. Even if they are not, it still doesn't change the fact that echoes of the project continue through the lifecycle of the product/service created. Many government (ie. community programs) and even corporate HR projects (ie. training portals) fall into this category. Saving Changes...
