The most correct action is to ensure full transparency and follow a documented process for managing potential conflicts of interest (COI). The assessor must immediately inform their C3PAO and the Organization Seeking Certification (OSC) of the prior relationship. This disclosure allows all parties to assess the risk to impartiality. The potential COI and the agreed-upon mitigation actions (e.g., having another assessor conduct that specific interview) must be formally documented in the assessment plan. If the mitigation is accepted by all parties as sufficient to ensure objectivity, the assessment can proceed. This approach upholds the integrity and impartiality of the assessment process as required by the Cyber AB.

A. Hiding a potential COI is a direct violation of the Cyber AB Code of Professional Conduct, which mandates objectivity and disclosure of any potential conflicts.

B. This is an extreme and premature action. The entire process does not need to be restarted if the specific conflict can be effectively mitigated and managed.

C. The assessor cannot unilaterally decide that a potential COI is non-existent. The perception of a conflict can be as damaging as an actual one, and all parties must agree on the path forward.

1. The Cyber AB

Code of Professional Conduct

Version 2.1 (June 28

2022).

Section 3.3

Conflicts of Interest: "Cyber AB Professionals shall proactively disclose any actual or potential conflicts of interest that may arise and take appropriate action to mitigate any such conflict." This directly supports the requirement to inform

document

and mitigate.

2. The Cyber AB

CMMC Assessment Process (CAP) for CMMC Level 2

Version 1.0 (July 21

2022).

Section 2.3.2

Conflict of Interest (COI) and Organizational Independence: This section requires the C3PAO to have a process to "identify

analyze

and document potential COIs arising from relationships" and "demonstrate how it will eliminate or mitigate such threats." This aligns with documenting the conflict and mitigation in the assessment plan.

3. ISO/IEC 17021-1:2015

Conformity assessment — Requirements for bodies providing audit and certification of management systems — Part 1: Requirements.

Section 5.2

Impartiality: This international standard

upon which CMMC assessment principles are based

requires certification bodies to "identify

analyse

document and eliminate or minimize threats to its impartiality on an ongoing basis." This reinforces the structured approach of identification

documentation

and mitigation described in the correct answer.
