Estimate Activity Resources Process

Estimate activity resources process is a project management process that is very important for the PMP certification exam. During the project, we need a number of resources to be able to implement the work that we define as part of the project and plan the processes necessary to perform this work. In the process of estimating project resources, we will then make an estimate of resource requirements that will play a role in estimating activity Times, developing a timeline, and determining costs and risks.

Estimate activity resources process is the second process in the project resource management knowledge area. In the estimate activity resources process we simply try to create an estimation of the team resources, the type and quantity of materials, equipment, and supplies necessary to be able to perform the project work.

Estimation of activity resources is a part of the Resource Management Knowledge Area and Planning Process Group.
