### Gap Assessment Summary

| Domain | Controls Assessed | Conforming | Minor Gaps | Major Gaps | Not Applicable |
|--------|------------------|------------|------------|------------|----------------|
| Organizational (A.5) | 37 | | | | |
| People (A.6) | 8 | | | | |
| Physical (A.7) | 14 | | | | |
| Technological (A.8) | 34 | | | | |
| **Total** | **93** | | | | |

## Phase 6: Remediation Planning
1. Prioritize gaps by risk severity
2. Assign remediation owners and deadlines
3. Define evidence requirements for each gap
4. Schedule follow-up assessments
5. Update risk treatment plan

## Counter-Rationalizations

| Shortcut | Counter | Why |
|----------|---------|-----|
| "We can skip some steps for this case" | Adapt the workflow steps, don't skip them | Skipped steps are where incidents and oversights originate |
| "The user seems to already know what to do" | Complete all workflow phases with the user | The workflow catches blind spots that experience alone misses |
| "This is a minor case, full process is overkill" | Scale the process down, don't turn it off | Minor cases become major when unstructured; the process scales, not disappears |
| "I'll fill in the details later" | Complete each section before moving on | Deferred details are forgotten; real-time capture is more accurate |
| "The template output isn't necessary" | Always produce the structured output format | Structured output enables comparison, audit trails, and handoff to other teams |

## Output Format
- **Audit Report**: Control-by-control assessment with findings
- **Gap Analysis**: Summary of non-conformities with severity ratings
- **Evidence Matrix**: Required evidence per control with collection status
- **Remediation Plan**: Prioritized actions with owners and deadlines
- **Statement of Applicability Update**: Revised SoA reflecting current state

## Action Items
- [ ] Complete documentation review for all ISMS documents
- [ ] Assess all 93 Annex A controls
- [ ] Document evidence collected per control
- [ ] Classify and prioritize all gaps found
- [ ] Assign remediation actions with deadlines
- [ ] Schedule management review of audit findings
