7. Estimate activity resources. Determine the types of resources, such as the skills or expertise required to perform each activity, as well as the quantity of each resource that may be needed. Resources include people, materials, equipment, and so on that may be required to perform each activity.

Resource estimates must consider the availability of each type of resource, whether it is internal or external (such as subcontractors), and the quantity available over the duration of the project. Designate a specific individual to be responsible for each activity.
