Administration, Supervision, and Management
Administration, Supervision, and Management is the Level III domain that tests the supervisor's side of instrument work: planning, documentation control, safety compliance, and the numbers used to justify decisions. Expect questions on work-order practice, calibration intervals, change control and the regulatory frameworks a maintenance group works inside.
What the exam tests
- CMMS discipline: every job raised as a work order with priority, craft, parts and closure notes; planned PM and predictive work scheduled against a visible backlog.
- Calibration interval management: intervals are shortened or extended from as-found failure statistics, not from budget pressure.
- KPIs: PM compliance proves the work was done; as-found failure rate, MTBF, MTTR and repeat-work rate show whether it worked.
- Change control: any field change to a control strategy or a safety instrumented function needs management of change, with P&IDs, loop sheets and drawings updated.
- Regulatory context: OSHA 29 CFR 1910.119 process safety management for covered processes, NFPA 70E for electrical safe work practices, IEC 61511 / ISA-84 for safety instrumented systems, and a live permit and lockout/tagout system.
Worked example
A site has 400 transmitters on a 12-month calibration cycle; 26 were out of tolerance as-found, a 6.5 % failure rate against a 5 % target. The defensible response is to analyse the 26 by service, model and drift direction, shorten the interval for the worst-performing group (say to 9 months), and leave the rest at 12 months. Cutting every interval doubles the workload; extending on cost alone leaves the failure rate above target with no supporting data.
Traps
- Treating 100 % PM compliance as proof of reliability.
- Extending intervals without as-found data to justify it.
- Forgetting that the shop's own calibration standards need calibration too.
- Field changes made without MOC, leaving drawings and the safety case out of date.
