Planning the project involves determining what needs to be done (scope, deliverables), how it will get done (activities, sequence), who will do it (resources, responsibility), how long it will take (durations, schedule), how much it will cost (budget), and what the risks are.

What then is different about the project scope document compared to the project charter? Who is responsible for preparation of the project scope document?
