4.3.3.3 Change Requests
A change request is a formal proposal to modify any document, deliverable, or baseline. An approved change request will replace the associated document, deliverable, or baseline and may result in an update to other parts of the project management plan. When issues are found while project work is being performed, change requests are submitted, which may modify project policies or procedures, project scope, project cost or budget, project schedule, or project quality. Other change requests cover the needed preventive or corrective actions to forestall negative impact later in the project. Requests for a change can be direct or indirect, externally or internally initiated, and can be optional or legally/contractually mandated, and may include:
Corrective action-An intentional activity that realigns the performance of the project work with the

project management plan;
Preventive action-An intentional activity that ensures the future performance of the project work is

aligned with the project management plan;
Defect repair-An intentional activity to modify a nonconforming product or product component;

Updates-Changes to formally controlled project documents, plans, etc., to reflect modified or additional

ideas or content.

6.6.3.1 Schedule Baseline
A schedule baseline is the approved version of a schedule model that can be changed only through formal change control procedures and is used as a basis for comparison to actual results. It is accepted and approved by the appropriate stakeholders as the schedule baseline with baseline start dates and baseline finish dates. During monitoring and controlling, the approved baseline dates are compared to the actual start and finish dates to determine whether variances have occurred. The schedule baseline is a component of the project management plan.
Process: 6.7 Control Schedule
Definition: Control Schedule is the process of monitoring the status of project activities to update project progress and manage changes to the schedule baseline to achieve the plan.
Key Benefit: The key benefit of this process is that it provides the means to recognize deviation from the plan and take corrective and preventive actions and thus minimize risk.
