Assign an accountable owner for every recurring evidence set
A synthetic CMMC responsibility matrix linking assessment objectives, evidence sets, process owners, technical providers, reviewers, cadence, and escalation.
Process owner and evidence producer separated
Internal, shared, inherited, and external responsibilities visible
Review and signature authority named
Cadence and escalation included in the same row
Control ownership is too broad for daily work
Saying “IT owns access control” does not identify who exports the authorized-user list, who confirms terminated accounts, who reviews the exception, who stores the record, or who follows up when the MSP report is late. The matrix decomposes ownership into observable tasks.
Five roles are often needed
One person may hold several roles, but the roles should still be explicit so the process survives turnover and provider changes.
- Process operator: performs the recurring activity.
- Evidence producer: creates or exports the proof.
- Evidence coordinator: requests, tracks, and files the proof.
- Qualified reviewer: determines whether the evidence supports the requirement.
- Decision authority: approves exceptions, resources, and affirmation.
Connect the matrix to the chase process
A responsibility document becomes operational when each row has a cadence, request path, backup owner, escalation authority, and expected output. Gridex maintains those links in the evidence ledger and chase log.
What the working artifact can contain
| Evidence set | Operator | Producer | Coordinator | Reviewer | Escalation |
|---|---|---|---|---|---|
| Authorized-user review | Client IT | MSP | Gridex | vCISO | COO |
| Security training | HR | LMS owner | Gridex | Security lead | COO |
| Visitor records | Facilities | Facilities | Gridex | Security lead | Operations director |
| Annual affirmation packet | Program owner | Multiple owners | Gridex | RPO/vCISO | Affirming Official |
Synthetic example — responsibility assignments must be tailored to the actual organization.
Concrete, client-owned operating records
Facts, not verdicts
The matrix documents assigned responsibility. It does not transfer the organization’s contractual responsibility or the assessor’s authority.
Frequently asked questions
Is this the same as a CRM or SRM?
It is related but more operational. A CRM/SRM allocates responsibility; this matrix also identifies evidence outputs, dates, coordinators, reviewers, and escalation paths.
Can an MSP own the evidence?
An MSP can produce and maintain evidence for responsibilities it performs. The contractor still needs the relationship and evidence mapped within its assessment scope.
