The cost estimating process associates an expected cost of performing work to each activity. Cost estimates can include labor, materials, equipment, and any other direct costs for project activities. Based on the activity resource and duration estimates, the cost estimates express the cost, normally in monetary amounts, of completing the work of the project. As with all project documents, the cost estimates can change throughout the project as conditions change. Different events can cause the cost for any activity to go up or down and require the cost estimates for the project to change. Table 3.11 shows the inputs, tools, techniques, and outputs for the cost estimating process.

Cost estimates are compiled into the project budget. The cost budgeting process aggregates the activity cost estimates into a single document for the project. The resulting project budget expands on the preliminary budget from the project charter and provides far more detail. Table 3.12 shows the inputs, tools, techniques, and outputs for the cost budgeting process.
