This lesson provides an overview of budget methods evaluation including:
There are a number of methods that can be used either separately or in combination to develop a budget. This lesson will focus on three methods:
In addition to these budget estimating methods, a project manager might use reserve estimating or contingency estimating to calculate the amount of money a project budget might increase over the project's lifecycle.
Using a reserve helps control budget overages by allocating the money up front. Once a budget has been estimated, it's the project manager's responsibility to document the budget so that the information can be communicated to stakeholders and team members. However, before submitting the budget, it should be evaluated for accuracy.
A budget has been created for a website development project. It might look like this:
The budget could contain the subtotals for each significant phase. In addition, the cost for the management staff would be included. If development software is needed by the project, that would also be included. A contingency of 12% could be added to account for possible cost and schedule overruns.
Before finalizing this budget and seeking approval for the money, a project manager should ask the following questions:
Have the scope and the schedule been reviewed for real costs?
Have they been added to the budget?
Does the budget reflect the cost of people resources?
Does the budget reflect the cost of non-people resources?
Does the budget include any reserves in the event the project runs over cost?
Have the team members been consulted about the effort and budget estimates?
Only after these questions have been answered positively, will a budget be considered realistic and ready for approval.
In this lesson, you learned three various budget methods that can be used to create a project budget. They are Actual budgeting, Roll-up (or Bottom-up) budgeting, and Comparison budgeting. You also learned that prior to seeking approval, a project manager must evaluate the budget for things like reserves, people and non-people resources, and make sure team members are consulted about effort and budget estimates.
