In the world of compliance, Plans of Action and Milestones (POA&Ms) have become a critical tool for organizations aiming to meet NIST frameworks like the Cybersecurity Maturity Model Certification (CMMC). However, how POA&Ms are used (and sometimes misused) can directly impact assessment outcomes.
The definition of a POA&M is referenced in 32 CFR as “…a document that identifies tasks needing to be accomplished. It details resources required to accomplish the elements of the plan, any milestones in meeting the tasks, and scheduled completion dates for the milestones, as defined in NIST SP 800–115” (83219).
The History of Misused POA&Ms
For a while, POA&Ms were treated by some organizations as a way to delay actual remediation. Instead of fixing security gaps, companies would list incomplete controls under POA&Ms with little intention, or no clear plan to resolve them promptly. This behavior allowed systems to pass audits on paper, even when significant vulnerabilities remained.
Today, that approach is no longer acceptable. Current regulations now require POA&Ms to be closed within 180 days, enforcing real accountability and turning POA&Ms into time-bound commitments, not placeholders. “This rule was updated to allow POA&Ms for no more than 180 days to give contractors the ability to achieve contract award without being fully compliant with all requirements of NIST SP 800–171 R2” (32 CFR, 83213).
What Makes an Effective POA&M?
A strong POA&M should go beyond identifying a problem. It must provide:
- Specific details on the unmet control(s)
- A clear explanation of the deficiency
- Defined steps for remediation
- Assigned responsibility
- Deadlines and milestones for completion
Assessors expect detailed documentation showing that remediation efforts are not only planned but actively underway. Properly managed POA&Ms demonstrate both transparency and organizational maturity.
Where Does an Operational Plan of Action Come In?
An operational plan of action, or an OPA, is often confused with POA&Ms; but they serve a very different function. OPAs are internal tools created by the organization, not by an assessor, and have no set timeline for completion. They are used to manage and track security improvement initiatives proactively before an audit occurs.
“An operational plan of action does not identify a timeline for remediation and is not the same as a POA&M, which is associated with an assessment for remediation of deficiencies that must be completed within 180 days” (32 CFR, 83219).
A POA&M works differently. They are formal documents that are tied to a compliance finding with a defined closure window. Whereas OPAs are strategic planning documents that allow teams to address risks on their own terms. Both are extremely valuable, but confusing the two can lead to compliance failures.
Managing External Providers in Your Environment
Many organizations bring in third-party providers to assist with remediation. While this can be effective, it can also introduce new risks on both sides (client and service provider) if not carefully controlled. External providers should be:
- Properly vetted
- Given appropriate level of access
- Documented thoroughly to ensure traceability
Poor management of external resources can unintentionally introduce new compliance issues, particularly around system changes and data access. That being said, organizations must develop mature internal processes for managing external access, especially in such a regulated environment.
Now Moving Foward: Structure, Strategy, and Documentation
As CMMC and other cybersecurity standards mature, successful organizations are those that treat their documentation like the living compliance strategies that they are. When used properly, POA&Ms show progress, buy time, and demonstrate clear commitment to closing gaps. OPAs offer the flexibility to stay ahead of compliance needs internally.
