Assessor Independence When the Assessor's Employer Is the Operator
A contract assessor is engaged to conduct an SMS assessment of a pipeline operator. The assessor's firm also provides the operator with control-room staffing consulting worth roughly 30% of the firm's annual revenue from this client. The assessor personally wrote the operator's emergency response plan two years ago, which is now one of the elements under assessment. The assessment scope includes emergency response, management review, and incident investigation. The operator asks the assessor to 'keep it efficient' and suggests limiting interviews to management because frontline staff are busy during a seasonal peak. The assessment report will feed a certification decision.

Three distinct threats:
- Self-review threat. The assessor wrote the emergency response plan now being assessed. Evaluating one's own work is the textbook self-review conflict. Remedy: recuse the assessor from the emergency response element and assign an independent assessor, or have an independent reviewer validate that element's conclusions.
- Financial/self-interest threat. Consulting revenue at ~30% of firm revenue from this client creates pressure to soften findings. Remedy: disclose the relationship to the certification body, and have the certification decision made by someone with no stake in the consulting relationship. If the conflict cannot be mitigated, the firm should decline the engagement.
- Scope-limiting pressure. Restricting interviews to management during a peak directly undermines assessment validity - frontline staff hold the operational reality. Remedy: refuse the limitation and explain why; if access is genuinely constrained, reschedule rather than produce a management-only assessment that cannot support a certification decision.
The overarching principle: the report feeds a certification decision, so objectivity must be demonstrable, not merely asserted.
2. The operator insists on the management-only interview scope. What should the assessor do, and what would a defensible report look like?

The assessor should not proceed on a management-only basis for an assessment that will support certification. Options, in order of preference:
- Reschedule to a period when frontline staff are available.
- If rescheduling is impossible, narrow the scope explicitly and state in the report that frontline verification was not performed, so the certification decision-maker knows the evidence base is incomplete.
A defensible report would:
- State the scope limitation prominently and its effect on conclusions for each affected element.
- Mark elements where frontline evidence was unavailable as not fully verified, not as conforming.
- Document the recusal on emergency response and who performed that element.
- Disclose the consulting relationship and the independence mitigations applied.
Proceeding silently, or reporting conformance on management interviews alone, would misrepresent the evidence and compromise the certification. The assessor's obligation is to the integrity of the conclusion, not to the client's convenience.
