OPS.8.2:1 - Problem frame

Use this when a person, machine or computing resource has idle intervals reserved for another service, and useful auxiliary work could occupy those intervals. An operator could prepare the next job or practise a skill. A machine could run an experimental batch. A computing resource could run a background analysis. Each choice is useful only if its interruption or completion leaves the required service available on the terms being protected.

Construct a usable arrangement: eligible auxiliary work, conditions for starting it, what triggers its end or interruption, and how the resource becomes ready for the protected work. The first result can be a short timing comparison that accepts one candidate and rejects another.

Start from the protection already selected through OPS.8: what work needs which capability, amount of resource, response time and access. If an existing arrangement meets those conditions and the proposed auxiliary work changes none of them, apply it. Choosing a learning goal or an improvement experiment belongs to the corresponding development method; this pattern establishes whether its execution fits the operation.
