The core concept of project cost management
"Project cost management focuses on the cost of resources required to complete the project activities, but should also consider the impact of project decisions on the use, maintenance, and support costs of the project's products, services, or results."
"Another aspect of cost management is to recognize that different parties will use different methods to measure project costs at different times."
