Per the CMMC Assessment Process (CAP), when planning an assessment, the Lead Assessor must coordinate with the Organization Seeking Certification (OSC) to select interview participants who can provide clarity and understanding of their practice activities. The intent is to interview individuals directly involved with and knowledgeable about the processes and practices under review, rather than selecting personnel based solely on rank, clearance, or formal expertise in CMMC.

This ensures the assessment is evidence-based and grounded in how practices are actually performed within the OSC.
