POA&M Best Practices Under CMMC 2.0
The Plan of Action and Milestones is one of the most misunderstood artifacts in the CMMC ecosystem. Defense contractors treat it as either a formality (filled in hastily before an assessment) or a threat (evidence of non-compliance). In reality, a well-managed POA&M is one of your most powerful tools for demonstrating compliance maturity and managing remediation effectively. Here’s how to do it right.
What the POA&M Is (and Isn’t)
A POA&M is a documented plan for remediating known security deficiencies within a defined timeframe. Under CMMC 2.0, POA&Ms are specifically addressed in the Level 2 context: organizations can achieve a ‘conditional’ certification with certain open POA&M items, provided those items fall within parameters defined by the Cyber AB and the assessing C3PAO.
The POA&M is not a confession document—it’s a management tool. It demonstrates that you’ve identified gaps, assigned ownership, set realistic timelines, and are actively managing remediation. Assessors look favorably on well-managed POA&Ms because they signal organizational discipline, not just compliance gaps.
CMMC 2.0 POA&M Parameters You Must Understand
Under CMMC 2.0, not all findings are POA&M-eligible. Certain high-priority practices—particularly those in the Access Control and Identification and Authentication domains—may not be deferrable to a POA&M and could prevent certification entirely. Work with your CMMC MSP to identify which practices are POA&M-eligible and which require immediate closure before your assessment.
POA&M items that are accepted must have: a specific remediation action defined, a responsible party named, a realistic target completion date (generally no more than 180 days from assessment), and documented progress tracked over time. These requirements are defined in 32 CFR Part 170.
Building a High-Quality POA&M
A high-quality POA&M includes for each finding: the specific CMMC practice reference, a clear description of the gap, the root cause of the deficiency, the specific remediation action (not just ‘will fix’), the responsible party (by name, not just role), the target completion date, the current status, and evidence of progress (meeting notes, configuration changes, vendor quotes, etc.).
Vague POA&M entries like ‘will implement encryption by Q3’ without specific action steps are red flags for assessors. Specificity demonstrates that you understand the gap and have a real plan—not just an intention.
Integrating POA&M Management with Managed Services
Manual POA&M management in spreadsheets works for organizations with a handful of open items but quickly becomes unmanageable at scale. VSO integrates POA&M tracking into our managed services workflow—open items are tracked in a purpose-built compliance management tool, progress is reviewed monthly with clients, and evidence of remediation is automatically logged and organized for assessment purposes.
Your CMMC MSP should provide you with POA&M status visibility at all times, not just in the weeks before your assessment.
POA&M Review and Closure Discipline
Open POA&Ms without active progress are worse than having no POA&M at all—they document a gap that you’re not actively addressing. Establish a monthly POA&M review cadence: review each open item, update status, record progress evidence, escalate items approaching their target date without resolution, and formally close items with supporting evidence when remediation is complete.
Closed POA&M items with strong evidence documentation are among the most compelling artifacts in a CMMC assessment. They demonstrate the full compliance lifecycle: identify, plan, remediate, verify.
Conclusion
A well-managed POA&M is a sign of a mature compliance program, not a liability. Treat it as an operational management tool, build it with specificity, review it consistently, and close items with evidence. That discipline will serve you well in every CMMC Level 2 assessment.

Frequently Asked Questions
How many open POA&M items is too many for CMMC Level 2 certification?
There’s no published hard limit, but quantity matters less than quality and category. A handful of low-impact open items with clear remediation plans is far preferable to multiple high-risk items in critical control domains. The Cyber AB has discretion in determining what’s acceptable for conditional certification.
Can we submit a POA&M for a control we’ve never implemented?
For most controls, yes—if you meet the CMMC 2.0 eligibility criteria and the control isn’t in a non-deferrable category. Be honest in your assessment. Submitting a POA&M for a control you have no realistic plan to implement is not a sustainable strategy.
Who should own the POA&M in our organization?
The POA&M should be owned by your CISO, IT Director, or equivalent—someone with authority to assign resources and hold teams accountable. Your CMMC MSP can support the process, but organizational ownership must be internal.
How does the annual CMMC affirmation relate to our POA&M?
The annual affirmation requires a senior company official to confirm continued compliance. If you have material open POA&M items at affirmation time, you may need to disclose conditional compliance status. Keep your POA&M current so you know exactly what you’re affirming.
What’s the relationship between the POA&M and the System Security Plan?
The SSP documents your implemented controls—how they work and what they cover. The POA&M documents controls that aren’t yet fully implemented and your plan to remediate them. Together, they provide a complete picture of your compliance posture. Both must be maintained as living documents.
