A scope of work should contain all of the following EXCEPT:

A request for purchase (or purchase requisition) is a financial and procurement instrument used to authorize the acquisition of goods or services, and it exists as a separate document outside the scope of work. A SOW describes project objectives, deliverables, schedule, assumptions, and customer needs - it defines the work to be performed, not how materials will be procured or paid for. Including a purchase request inside a SOW conflates project definition with procurement administration, which are managed through distinct processes and approvals.

A project schedule is a required SOW component because it establishes milestones, deadlines, and the overall timeline against which deliverables are measured.

A project objective is a core SOW element that defines the goals and expected outcomes the work must achieve, giving all stakeholders a shared definition of success.

Assumptions are explicitly included in a SOW to document conditions presumed to be true that could affect scope, cost, or timeline if they change.

Customer needs are foundational to a SOW because they define the requirements and expected outcomes that the entire project is designed to satisfy.
