What is a Cost Management Plan?

A cost management plan is a document that outlines how project costs will be estimated, budgeted, managed, monitored, and controlled. It serves as a guideline for ensuring that the project stays within the approved financial boundaries while meeting its objectives. Developed during the planning phase of a project, this plan provides a structured approach to managing financial resources, helping project managers make informed decisions about spending and resource allocation. The plan may include procedures for cost tracking, approval workflows, reporting requirements, and variance analysis. It also identifies who is responsible for various cost-related tasks throughout the project lifecycle.

The plan includes a monthly cost reporting schedule, approval levels for additional expenditures, and procedures for managing cost changes. By following this plan, the team ensures that all project expenses stay within the approved $50,000 budget.
