Actual project progress and performance are monitored against the project plan.
Monitoring acquirer project progress and performance begins as soon as a plan is established. The acquirer is responsible for monitoring the progress and output of the project. After a supplier is selected and a supplier agreement
put in place, the acquirer’s monitoring and control activities extend to the supplier and its activities. The acquirer monitors supplier progress, including achievement of requirements established in the supplier agreement and using specified
process, product, and service level measures.
