OPS.9:4.5 - Compare treatments from the current arrangement

Compare the incumbent with a finite change that acts on the supported mechanism. Candidate treatments include protecting usable constraint time, changing release or dispatch, completing prerequisites earlier, reducing avoidable setup or rework, obtaining capacity, or changing a domain Method.

Account for implementation effort, transition loss, displaced work, downstream congestion, affected commitments and reversibility. Use C.11.CRC for the finite comparison and C.11 for the choice when several admissible alternatives remain. Resource acquisition is not preferred merely because it is easy to count.

A treatment is supported only to the scope of the evidence. A deterministic scenario can show feasibility; it does not establish actual field effectiveness. A probe can support a bounded effect without showing that the same treatment remains useful under another demand regime.
