OPS.11:4.1 - Start from the proposed operating change
Name the operating result, current arrangement, proposed change and horizon. State which consequence would make the change useful or unacceptable. Reuse the current OPS.1–OPS.4 account and a matching OPS.8–OPS.10 result where available.
Select the affected Systems and participants by the actual consequences, not by the organizational chart alone. A supplier, customer, operator or neighboring service can matter without appearing inside the local department boundary.
If one direct pattern already settles the decision and no cross-structure relation can change it, use that result and stop.
