Final answer:
Estimating activity resources is not a function of cost management. It is a part of the project management process that involves identifying and quantifying the resources needed for each activity in a project.
Step-by-step explanation:
The correct answer is False. Estimating activity resources is not a function of cost management. It is a part of the project management process that involves identifying and quantifying the resources needed for each activity in a project. This includes determining the types and quantities of materials, equipment, and labor required. Cost management, on the other hand, focuses on estimating, budgeting, and controlling the costs of a project.
