Organization-sustaining activities are carried out regardless of which customers are served, which products are produced, how many batches are run, or how many units are made.

Organization-sustaining activities are basic activities that must be performed to keep any business functioning regardless of the volume of the products being produced or sold. Examples of such activities include accounting, administration, legal work, facility maintenance, and safety inspections. These activities are not tied to a specific customer or product and are necessary for the overall sustainability of the organization.
