Budget

The budget for a project consists of the budget allocated to control account work packages or planning packages and any summary level planning packages scheduled to accomplish work scope defined in the project's work breakdown structure (WBS) as well as related statement of work (SOW) or statement of objectives (SOO). Work packages and planning packages are equivalent to tasks or activities in a network schedule with a defined start date, end date, and durations. Resources assigned to a work package or planning packages are equivalent to resource loaded activities in a network schedule. The work package and planning package start and end dates determine the time frame for the time phased budget data.

Contractual documents typically determine the target cost for the project or contract budget base. Minus any budget set aside for management reserve to handle risks, this determines the total budget available to be distributed to the work packages and planning packages to establish the budget baseline or performance measurement baseline. See Budget Distribution for an illustration of the budget element hierarchy.

The time phased budget data is the foundation for performing the project's planned work effort. Ideally, it is produced from a network schedule of resource loaded activities that reflect the planned sequence of work and resource requirements to produce the related staffing plan. Once you have established the budget baseline, the intent is to measure work and financial performance on a regular basis, typically every accounting calendar period. You advance the calendar each reporting period to assess work progress and the actual costs incurred to do the planned work for the current reporting period so you can proactively manage the remaining work effort, the estimate to complete, and make any course corrections.
