Consumption - The measurement of actual use of consumable items to the planned use (budget to actual).
Materials under grants and contracts must be "consumed" or expended for the planned use. They include assemblies, components, parts, raw and processed materials, and small tools and supplies that may be consumed in normal use in performing the business objective.
The consumption process measures actual use against planned use of materials identified to build items in the production, manufacturing, research and development process, or for services.
