Guide to Resource Aggregation in PMP: PMBOK 7th Edition

Resource Aggregation is a critical aspect within project management, as defined in the PMBOK Guide 7th Edition.

What is Resource Aggregation?
Resource Aggregation involves the summing up of all resources planned or currently being used in a project. It includes the estimate of the types and quantities of material, human resources, equipment, and supplies necessary to perform project activities.

Why is Resource Aggregation important?
It is vital as it determines the cost and time needed to complete the project. Furthermore, it helps streamline effort and prevents the oversupply or undersupply of resources.

How it works?
Resource Aggregation works by mapping all necessary resources to each task or activity within a project. Then, each allocated resource is quantified and summed to identify total resource needs.
