MA.2:1 - Problem frame

A team pays for a resource arrangement that supplies capability over time. Some provision can be unavailable for the relevant service; some usable capacity can support actual work; some can protect the service against variation. A remaining unused portion may offer another use or a possible supply change.

These quantities do not have one monetary meaning. Released time can increase available capability without changing the current payment. A supply reduction can save money while also removing capacity needed in another time window.
