Administration, Supervision and Management
This domain tests the supervisory side of instrumentation work: assigning qualified technicians, controlling calibration intervals, reviewing records, managing safety and contractors, and making defensible decisions when production pressure conflicts with maintenance requirements. Level II expects practical judgment, not general management theory.
Core rules
- Match the technician to the task. Verify qualifications, training and test-equipment status before assigning safety-critical or complex calibrations.
- Manage the calibration program through the CMMS: work orders, due dates, intervals, spare parts and backlog. Interval changes should be based on history and risk, not convenience.
- When an instrument is found out of tolerance, quarantine it, assess the impact on product or safety since the last good calibration, notify quality, and document disposition.
- Safety supervision includes job safety analysis, lockout/tagout, permit-to-work, toolbox talks, management of change and contractor control.
- Review and sign records for completeness: as-found/as-left data, traceability, technician identification and date. Do not accept a signature without the supporting data.
- Follow the ISA code of ethics: report accurate results, avoid conflicts of interest and protect public safety.
Worked example
Production asks to defer a calibration because the unit is running. The supervisor should classify the instrument. If it is safety-critical, environmental or regulated, deferral requires a management-of-change review, risk assessment and documented approval. If deferral is approved, record the new due date and monitor the loop. If the instrument is later found out of tolerance, evaluate product made since the last calibration and inform quality. The reasoning is that deferral is a risk decision, not a scheduling convenience.
Traps
Signing off work that was not performed; deferring PM without risk assessment; accepting contractor calibrations without checking traceability; failing to evaluate out-of-tolerance impact; and letting the backlog grow without escalation.
