Explanation
The project manager is the stakeholder who is responsible for writing the project scope. The project scope is a document that defines the work that needs to be done to deliver the project, including the objectives, deliverables, milestones, resources, and constraints. The project manager is the person who leads and coordinates the project team, plans and monitors the project activities, manages the project risks and issues, and communicates with the project stakeholders. The project manager works closely with the business analyst, who is responsible for writing the solution scope, which defines the features and functions of the solution that will address the business need. The project manager also consults with the domain subject matter expert, the implementation subject matter expert, and the sponsor, who are stakeholders who provide input, feedback, and approval for the project scope and the solution scope.
