According to the PMBOK® Guide (6th Edition), the Project Cost Management knowledge area is concerned with the processes involved in planning, estimating, budgeting, financing, funding, managing, and controlling costs so that the project can be completed within the approved budget.
There are exactly four processes within this knowledge area:
Plan Cost Management: The process of defining how the project costs will be estimated, budgeted, managed, monitored, and controlled.
Estimate Costs: The process of developing an approximation of the monetary resources needed to complete project work.
Determine Budget: The process of aggregating the estimated costs of individual activities or work packages to establish an authorized cost baseline.
Control Costs: The process of monitoring the status of the project to update the project costs and managing changes to the cost baseline.
Analysis of Distractors:
A (Develop Costs): " Develop Costs " is not a recognized PMI process name. The correct term is " Estimate Costs. "
B (Determine Risks): This process belongs to the Project Risk Management knowledge area. Additionally, " Develop Budget " is not a formal process name (it is " Determine Budget " ).
D (Plan Budget Management / Create Cost Accounts): While cost accounts exist within the Work Breakdown Structure (WBS), " Create Cost Accounts " is not a standalone process. " Plan Budget Management " is also incorrect; the process is " Plan Cost Management. "
Key Document Reference: Section 7.0 of the PMBOK® Guide introduces these four processes as the standard framework for ensuring financial integrity throughout the project life cycle.
