Top Down estimating is a project estimating technique whereby the overall project is estimated first, and individual tasks are apportioned from it. You start from the top of the pyramid and work downwards. This type of project budgeting usually occurs when there is a fixed budget and/or the scope of the project must fit within a predetermined funding level, … [Read more...]
Mismanaging project costs is the single fastest way to cause project failure. Project costs represent the many multi-faceted experiences that occur on a project, however stakeholders see only the bottom line and draw rapid conclusions from it. For this reason, the planning of the management of project costs is the focus of the Project Management Body of Knowledge's … [Read more...]

To prevent you from going up the creek without a paddle, a Cost Management Plan is the guiding document which allows you to take fast, decisive action when issues arise and the sharks are circling. The Project Cost Management Plan is the component of the overall Project … [Read more...]
The Budget at Completion (BAC) is a value used in earned value management, a division of project management. It represents the original project budget. For example, if a project has a budget of $10,000, BAC = $10,000 Therefore, there is no other formula or calculation for this metric. The BAC is often compared to the Estimate at Completion (EAC) which … [Read more...]
Love it or hate it, the measuring stick for a project manager is often their ability to keep projects on time and under budget. Thankfully, project management theory provides us with a fantastic tool to keep us on target. But it has to be used correctly.

The key to success, then, is to ensure that what actually happens is the same as the estimate. This might seem like magic sometimes, but it requires strong project cost estimation techniques. Project … [Read more...]
Three point estimating is a technique which utilizes an optimistic and pessimistic estimate to determine the ideal estimate value for a project task. It is a shoe-in for PMP exam questions, which is not likely to change anytime soon. It allows known risks to be quantified and built in to the project budget. Formula There are two generally accepted formulas for three … [Read more...]
