OPS.9:12 - Relations
OPS.1–OPS.4 supply matching operating focus, subject identities and current observations. OPS.8 supplies relevant queue, readiness and buffer policy; OPS.10 supplies usable-capacity and service comparisons; OPS.11 exposes couplings that can sustain or move a limiting relation.
OPS.5–OPS.7 consume supported operating-policy consequences under their own admission, continuation, priority and commitment authority. A domain Method change returns to its owner. OPS.16 is available for the separate local operating-Method-improvement question but is not a prerequisite for diagnosing the current constraint.
Current FPF C.16, C.27.TA/C.27, C.28, C.11.CRC and C.11 govern measurement, temporal and causal claims, finite contribution and choice. They do not supply a clinical, engineering, safety, labor or financial diagnosis merely by being cited.
