OPS.18:1 - Problem frame

Use this when an operating result may no longer meet its requirement, observed service failures exceed the agreed allowance, a recurring process changes, a lot needs acceptance or an incident raises a containment, recovery or recurrence-prevention question.

Begin with the result at risk, the affected population or configuration, and the action someone is authorized to take. Select the evidence method for that question. The first useful result is a decision about the affected work, service or output, together with the next action and the evidence and conditions needed to support it.

This pattern governs operating decisions about quality and reliability. A monitoring account is one input. A qualified product requirement, clinical decision, statistical method or engineering acceptance result may be another. If the question is only how to define and reconcile observations, use OPS.15. If a current response policy and adequate evidence already settle the action, apply them directly.

For example, twelve nonconforming items in a sample can trigger investigation under a process-monitoring rule. A lot-disposition decision still needs its own acceptance basis. Likewise, exhausting a software service’s error budget can pause discretionary changes while urgent restoration continues under the responsible authority.
