OEMS Drift Shows Up in the Field, Not in the Binder

OEMS self check 7 questions to detect operational drift early

Most operations can point to an OEMS. Fewer can show that it is actually running the work, across shifts, in the field, under pressure.

A quick reality test is simple.

Does your OEMS run the work, or does the work run around your OEMS?

Quick OEMS self check (7 prompts)

Answer yes or no. Only count “yes” if you can point to evidence, not intent.

  1. We have done a recent OEMS gap analysis and closed repeat findings.
  2. Our management system is integrated, not stove piped across functions.
  3. Operators can run with minimal reference to complex manuals.
  4. Leaders have role based behaviors (LSW) that we actually observe.
  5. We start changes with a small pilot and clear objectives.
  6. Risk management is embedded in every process, not duplicated.
  7. Audit frequency and assurance are tuned to detect drift early.

What your score suggests

If you checked 0 to 2
Start with a rapid assessment and pick one pilot unit. The goal is clarity, what is real, what is missing, what is being bypassed.

If you checked 3 to 5
Pick the weakest two items and tighten execution with field verification. Focus on closed loop follow through, not more documentation.

If you checked 6 to 7
Pressure test sustainability. Drift usually shows up in assurance quality, repeat findings, and leader routines that are assumed but not observed.

Three field tests that catch drift early

Field test 1, “show me” walkthroughs
Ask a supervisor and an operator to walk the same job, then compare what the OEMS says versus what actually happens.

Field test 2, repeat finding heat map
List your repeat audit findings and repeat incident themes, then trace each one to the exact OEMS element that should be preventing it.

Field test 3, leader routine proof
If LSW is real, you should be able to pull recent observations, coaching notes, and the resulting fixes, with owners and dates.

If you want a fast starting play

If you want a neutral third party to pressure test your OEMS, start with a Rapid Operational Assessment (ROA) and leave with a prioritized plan and a pilot path.

preventing repeat incidents in high risk operations

Why Do We Keep Having Repeat Incidents?

Repeat incidents aren’t caused by bad people or forgotten training. They come from system drift, weak feedback loops, overloaded supervisors, and corrective actions that don’t hold under pressure. This article
