Updates to project documents is an output of the Control Scope process. One of these documents is the requirements traceability matrix. It may need updates to reflect changes in requirements documents. 26. a. Requirements traceability matrix

It is an input to the Control Scope process as it helps to detect the impact of any change or deviation from the scope baseline to the project objectives. It also may provide the status of any requirements being considered. c. Cost baseline

Project Scope Management

27.

The cost baseline is included in the project management plan. It may need updates as part of the Control Scope process. Changes in the cost baseline are incorporated if there are approved scope changes, as in this question. Changes also may be needed to the cost baseline if there are changes in resources or cost estimates, both of which may be necessary from the scope changes. It some cases while controlling the scope, the cost variances that result may be so severe that a revised cost baseline is needed for a realistic basis for performance measurement.

28. d. Deliverables that have not been formally accepted

In the Validate Scope process, change requests are an output. They include documentation of the completed deliverables that have not been documented and the reasons why they were not accepted. These deliverables then may be ones that require a change request for defect repair. The change requests are processed through the Integrated Change Control process.
