TL;DR: CMMC readiness breaks most often on scope definition, evidence organization, and timing rather than on the controls themselves, according to Drata. The governance lesson is that compliance programmes fail when boundaries and proof are treated as last-step tasks instead of operating disciplines.
NHIMG editorial — based on content published by Drata: CMMC readiness guidance for Level 1 and Level 2 certification
Questions worth separating out
Q: How should organisations avoid CMMC scope creep during readiness planning?
A: Start with a boundary model that identifies where CUI can exist, which systems are in scope, and which identities can reach those systems.
Q: Why do CMMC programmes fail even when controls are technically in place?
A: Because assessors do not certify intent, they validate proof.
Q: What do teams get wrong about CMMC evidence collection?
A: They treat evidence as a pre-audit deliverable instead of an operating process.
Practitioner guidance
- Define CMMC scope before remediation starts Map CUI locations, user groups, privileged accounts, and third-party touchpoints into a single boundary model before collecting evidence or assigning tasks.
- Centralise identity and control evidence Keep access approvals, periodic reviews, system ownership, and remediation artefacts in one place so assessors can trace controls without manual reconstruction.
- Assign control owners across the lifecycle Make one team accountable for each control’s operation, evidence, and remediation path, including access governance and privileged account handling.

Drata's full article covers the operational detail this post intentionally leaves for the source:
- A practical breakdown of CMMC Level 1, Level 2, and Level 3 expectations for contractors and subcontractors.
- Partner workflow detail on how advisory, automation, and assessment hand off across the readiness lifecycle.
- Specific examples of how centralised evidence tracking reduces last-minute audit scrambling.
- The assessment path for organisations that need CMMC Level 2 certification rather than self-attestation.

CMMC fails when scope is treated as paperwork instead of an active governance boundary. The article is right to centre boundary definition because assessor outcomes depend on where CUI can live, who can touch it, and which systems are in play. That makes scope a control decision, not a documentation exercise. Practitioners should treat boundary governance as the first certification control.
A question worth separating out:
Q: Who is accountable when a CMMC Level 2 assessment finds scope or evidence gaps?
A: Accountability should sit with the programme owner, not just the assessor or the tooling team. Internal teams are responsible for defining scope, maintaining control evidence, and proving that access and documentation match the certification boundary. The assessor validates, but the contractor must own readiness end to end.
