Details:

Project Management Plan: The PMP includes the cost baseline, which represents the approved budget for the project. It also contains other subsidiary plans, such as the cost management plan and change management plan, which provide guidance on how project costs will be managed and controlled.

Project Funding Requirements: Project funding requirements specify the financial resources needed to execute the project. Understanding these requirements is essential for managing and controlling project costs effectively.

Work Performance Data: Work performance data includes information about the actual costs incurred on project activities, as well as any changes or issues affecting project costs. It serves as input for assessing project performance.

Organizational Process Assets: OPAs include organizational policies, procedures, and historical data related to cost management. These assets provide valuable insights and resources for controlling project costs.

Earned Value Management (EVM): EVM is a performance measurement technique that integrates scope, schedule, and cost data to assess project performance. It involves comparing planned costs, earned value (the value of work completed), and actual costs to determine variances and forecast project outcomes.

Variance Analysis: Variance analysis involves comparing actual project costs against the planned budget to identify variances. Positive variances (under budget) and negative variances (over budget) are analyzed to determine their causes and impacts on project objectives.

Performance Reviews: Performance reviews involve assessing the progress of project activities against the planned budget. This may include regular meetings with project team members, stakeholders, or subject matter experts to review work performance data and identify any deviations from the budget.

Change Control: Change control processes are used to manage changes to the project scope, schedule, and budget. This may involve evaluating change requests, determining their impact on project costs, and obtaining approval before implementing changes.

Work Performance Information: Work performance information includes updates on the status of project costs, cost performance indicators, and any issues or changes affecting project costs. It provides valuable insights for decision-making and corrective action.

Change Requests: Change requests may be generated as a result of cost variances or unforeseen circumstances. These requests undergo the change control process for evaluation, approval, and implementation.

Project Management Plan Updates: Updates to the project management plan may include revisions to the cost baseline, cost management plan, or other subsidiary plans to reflect changes and updates related to cost control.

Project Document Updates: Updates to project documents may include revisions to the risk register, issue log, and lessons learned documentation to reflect changes and updates related to cost control.
