Once the tasks within the project have been defined, the resources required by each task must be determined. To do this, we consult the PMBOK's Estimate Activity Resources process. PMBOK, 5th Edition, Section 6.4, "Estimate Activity Resources" Estimate Activity Resources is the process of estimating the type and quantities of material, human resources, equipment, or...

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...

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 very...

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... [Read More]| ProjectEngineer
Once the project has been divided into tasks and resources assigned to those tasks, the next step is to determine the task durations. This may seem trivial, but its importance cannot be understated because these durations will be used to construct the project schedule. Just like the tiny O-rings that brought down the space shuttle... [Read More]| ProjectEngineer
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...

Bottom up estimating is the project management technique of estimating individual tasks and then combining them into an overall project estimate. Often the individual project team members who will be performing the task provide the estimates, because they are in a better position to estimate a task that they will be working on. Types of...

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...
