OCE.11:4.1 - Recover the service that the change can disturb

Name the continuing contribution, receiving users, current commitments, operating configuration and interval. Ask the service owner for the applicable coverage, response, protection and recovery conditions and the evidence that supports them.

Identify the particular change contribution and the resources it can consume or interrupt. Do not substitute total staffing, average utilization or a free calendar for the qualified service result. When coverage under variability, a buffer policy or a service-credibility judgement is needed and not supplied, obtain that professional result before relying on it.
