No ATO is mathematically 100% risk-free. The realistic goal is to make the system control posture, evidence, residual risk, and remediation plan clear enough that an agency Authorizing Official can make an informed decision.
What Close To Complete Means
| Dimension | Close To Complete | Not Close Enough |
|---|
| Documentation | Every official artifact has current source material, owner, and evidence reference. | Policies exist but are generic or not tied to controls. |
| Implementation | Required controls operate in the system or are explicitly inherited. | Controls are described as future intent without POA&M. |
| Evidence | Evidence is produced by normal workflows and retained. | Evidence must be recreated manually for assessment. |
| Risk | Gaps are visible, scored, owned, and time-bound. | Gaps are hidden, vague, or unowned. |
| Agency fit | AO can see customer impact, data sensitivity, and residual risk. | Package assumes one-size-fits-all risk tolerance. |

Acceptable Wiggle Room
| Area | Usually Negotiable | Usually Not Negotiable |
|---|
| Timing | Remediation date for lower-risk findings. | Unowned high-risk findings. |
| Evidence format | Screenshot versus API export during early template review. | No evidence at all for implemented controls. |
| Tool choice | Equivalent scanner, SIEM, policy engine, or ticket system. | No repeatable process for scanning, logging, or access review. |
| Control inheritance | Provider-managed controls with package evidence. | Informal assumption that a provider handles a control. |
| Manual process | Time-bound manual review with owner and evidence. | Manual process with no cadence or retention. |
AO Brief Outline
- Mission and system purpose.
- Authorization boundary and baseline.
- Data sensitivity and FIPS 199 result.
- Implemented control posture.
- Inherited and shared controls.
- Evidence production model.
- Open POA&M items and remediation dates.
- Risks requested for acceptance.
- Continuous monitoring commitment.
- Significant-change and incident-reporting commitments.
Readiness Verdict
Use this verdict language internally until the package is assessed.
| Verdict | Meaning |
|---|
| Documentation Ready | The package is ready for sponsor, 3PAO, or AO review, but implementation evidence may still be partial. |
| Execution Ready | Controls are implemented and evidence is generated by normal operations. |
| Assessment Ready | Documentation, implementation, evidence, and POA&M are ready for formal 3PAO assessment. |
| Authorization Decision Ready | Assessment results, POA&M, and residual risk are ready for AO decision. |
Non-Negotiable Honesty Rule
Do not state that the system is FedRAMP compliant, FedRAMP authorized, or ATO approved from these template documents. State that the package maps to FedRAMP and NIST 800-53, that it is preparing for a target baseline, and that the final decision belongs to the agency Authorizing Official.
