As a project manager, your projects may be allocated the resources needed by the organization's PMO. You are likely to be most concerned with securing the resources you need for your project, but the PMO is going to be focused on allocating the resources available to the right projects at the right time. When you articulate the project deliverables and the associated tasks and work packages clearly, the scope of the project is well-defined and helps to ensure delivery of the project outcomes successfully and within the project schedule.
