MA.1:1 - Problem frame

A service can use a machine, qualified staff, consumables and a supplier’s processing service to deliver one accepted result. Each resource has a different relationship to the work. The machine is occupied during setup and processing; staff may supervise only part of that time; consumables may be used on unsuccessful attempts as well as accepted units. A supplier may charge for an attempt, a completed batch or a reserved block.

The money follows further relationships. Stock consumed today may have been paid for last month. Salaried capacity may be available within unchanged pay. Another machine block may require a payment before the customer pays. An internal unit-cost report may also assign a share of the building and management costs. These amounts can all be meaningful while answering different questions.

Management accounting needs an explanation connecting those facts. The relevant boundary follows the work, resource behavior and receiving use; it need not coincide with the chart of accounts or an organizational department.
