OPS.9:3 - Forces
| Force | Practical tension |
|---|
| urgent treatment and adequate diagnosis | Delay can be costly, but the wrong treatment consumes resources and can move congestion elsewhere. |
| one focal constraint and distributed delay | Focusing effort helps, while several short waits or alternating regimes can defeat one-resource explanations. |
| local measures and accepted results | Touch time, busy time and queue length can change without changing what the operation delivers. |
| useful probes and protected conditions | A probe can discriminate explanations only while preserving the relevant professional, acceptance and comparison conditions. |
| learning and migration | A useful treatment changes the arrangement; its success can make the former constraint cease to be current. |
