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...]
Easy Earned Value Tutorial
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. Like a software tool, if you are not trained to use it, it’s just a bunch of numbers. Once the technique is … [Read more...]
How to Produce a Detailed Estimate
Estimating a project is one of the most important aspects of project management. Projects are by definition temporary endeavors with a defined beginning and end, hence stakeholders need to know how much expenditure they are committing to. Thus, project estimates tend to start before the project even begins and are usually updated throughout the project life … [Read more...]
The Rough Order of Magnitude Estimate
Project estimating is one of the most important aspects of project management. By their very nature, projects have fixed budgets and their owners want to know how much they will cost. Hence, project estimating begins prior to project initiation and estimates are usually updated at important project milestones. A Rough Order of Magnitude estimate, often called ROM … [Read more...]
11 Types of Estimates
Almost every project requires an estimate. Since a project is, by definition, temporary, somebody must approve a budget for it. Which means they must know how much to approve. The available types of estimates can be categorized into the following groups: Accuracy Source of Data Estimating techniques Accuracy In many industries, project estimates start … [Read more...]
Project Cost Estimation 101
Project estimating requires predicting the future. Like ancient prophets and soothsayers, today's project managers are experts in telling people what is going to happen. 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 for the PMP Exam
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...]
Parametric Estimating for the PMP Exam
Parametric estimating is a guaranteed inclusion on the PMP Exam. This article is assured to give you at least one point (but more likely four or five). Parametric estimating is a project estimation technique whereby a unit rate is used and multiplied by the number of units. For example: A house building project is estimated at $120 per square foot A contractor … [Read more...]
Estimate to Complete (Earned Value Analysis)
In earned value analysis, the Estimate To Complete, usually abbreviated ETC, is the expected remaining cost to complete the project. It is not the final overall project cost (that's the EAC), rather it is the expenditure from now to the end of the project. It does not include what has already been spent. Thus, it allows the project manager to compare the funding needs … [Read more...]
