Evidence Collection Approach

CMMC assessments and certification require substantial evidence and documentation. The following tables outline general guidelines for collecting evidence to assess control requirements and objectives. While these guidelines provide a structured approach, they are not the only means of conducting an accurate assessment. Assessors should exercise professional judgment and may employ alternative methods appropriate to the specific organizational context and circumstances.

Evidence collection approaches are defined as:

• Documentation: Tangible materials containing information over which an organization has authority, including all types of written records and their copies.
• Artifacts: Tangible, reviewable records directly resulting from a practice or process being performed by a system or by personnel executing their role within that practice, control, or process.
• Physical Review: Direct on-site observation and examination of evidence.
• Screen Share: Real-time remote observation of a user demonstrating a task or process via shared computer screen, sometimes called "over-the-shoulder" review.
