TOPIC: ITTOs for Identify Stakeholders 13.1

Good question, but I think it's because high level requirements are defined through the Business Case into the Project Charter, so you may have a general idea that you need a Procurement Contract. But can the Procurement be conducted to where you know who the Seller is, so now you can add them as a Stakeholder?

Let's hope one of the experts can chime in.

page 394 PMBOK there is an if statement.
If a project is result of proc activity or is based on an established contract the parties in that contract are key stakeholders.
