According to the PMBOK® Guide, the Control Procurements process is the process of managing procurement relationships, monitoring contract performance, making changes and corrections as appropriate, and closing out contracts.
The two key benefits identified in the PMI standards are:
B. Ensures that contract performance meets the terms of the legal agreement: This process involves both the buyer and seller. It ensures that the seller’s performance meets the project ' s requirements and that the buyer performs according to the terms of the legal contract (such as making timely payments). It involves reviewing and documenting how a seller is performing to ensure the desired results are achieved.
D. Assures that legal agreements guide contract closings: Control Procurements includes the administrative activities involved in finalizing a contract. It ensures that all deliverables have been accepted, all payments have been made, and all contractual obligations have been fulfilled before the contract is formally closed.
Analysis of other options:
A and E (Make-or-buy decisions and contract type selection): These are key benefits and activities of the Plan Procurement Management process. These decisions must be made during the planning phase, well before a contract is active.
C (Vendor selection): This is the primary focus of the Conduct Procurements process, which involves receiving seller responses, selecting a seller, and awarding a contract.
Per the PMI standards, Control Procurements is unique because it has a significant legal component, requiring the project team to be aware of the legal implications of the actions taken when managing the relationship with the seller.
