- [✓] Feature meets measurable outcomes defined in Success Criteria
- [✓] No implementation details leak into specification

## Validation Summary

**Status**: ✅ PASSED

All checklist items have been validated successfully:

### Content Quality Analysis
- ✅ The spec focuses on WHAT developers need (reverse engineering process) without specifying HOW to build the documentation system
- ✅ User stories describe developer workflows and business outcomes (reduced onboarding time, fewer bugs)
- ✅ Language is accessible - explains concepts like "PowerShell reference module" and "API endpoint pattern"
- ✅ All 3 mandatory sections present: User Scenarios & Testing, Requirements, Success Criteria

### Requirement Completeness Analysis
- ✅ Zero [NEEDS CLARIFICATION] markers in the spec
- ✅ All 8 functional requirements (FR-001 to FR-008) are testable: can verify if documentation includes each specified element
- ✅ All 6 success criteria (SC-001 to SC-006) have numeric targets: 2 hours, 95% accuracy, 50% reduction, etc.
- ✅ Success criteria avoid implementation details (e.g., "developer can implement" not "TypeScript code compiles")
- ✅ Each user story includes 2-3 acceptance scenarios with Given/When/Then format
- ✅ Edge cases section covers 4 scenarios: PowerShell updates, deprecated features, missing references, quirky behaviors
- ✅ Scope is bounded: focuses on reverse engineering strategy, not the actual implementation of sync jobs
- ✅ Dependencies documented: requires `IntuneManagement-master/` directory as reference source (FR-002)

### Feature Readiness Analysis
- ✅ All functional requirements map to user story acceptance scenarios:
  - FR-001 (step-by-step process) → User Story 1 Scenario 1
  - FR-003 (data points to extract) → User Story 1 Scenario 2
  - FR-005 (troubleshooting section) → User Story 2 Scenarios
  - FR-007 (versioning strategy) → Edge Case 1
- ✅ User stories cover complete workflow: implementation (P1) → troubleshooting (P2) → knowledge transfer (P3)
- ✅ Success criteria align with user outcomes: SC-001 (time savings) validates User Story 1, SC-004 (onboarding) validates User Story 3
- ✅ No implementation leakage detected (e.g., doesn't specify markdown vs wiki vs code comments for documentation format)

## Notes

This specification is ready for `/speckit.plan` or implementation. No further clarifications or revisions needed.

**Next Steps**:
1. ✅ Implementation complete - all tasks executed
2. ✅ All 8 functional requirements validated in guide
3. ✅ Guide published at `docs/architecture/intune-migration-guide.md`

## Implementation Validation (2025-12-09)

### Functional Requirements Validation

**FR-001**: Step-by-step process ✅
- Section "Step-by-Step Implementation Process" includes 6-phase workflow
- Each phase has concrete actions (e.g., "Find the Graph API call", "Look for property deletions")

**FR-002**: PowerShell reference location ✅
- Section "PowerShell Reference Location" specifies `reference/IntuneManagement-master/`
- Lists key directories: Modules/, Extensions/, Core.psm1
- Provides search examples for finding modules

**FR-003**: Data points to extract ✅
- Section "Data Points to Extract" has comprehensive checklist
- Required: endpoints, query parameters ($filter, $expand, $select), property cleanup, type transformations
- Optional: nested objects, conditional logic, batch operations

**FR-004**: Concrete examples ✅
- 4 detailed examples in "Concrete Examples" section
- Example 1: Windows Update Rings (full implementation)
- Example 2: Settings Catalog ($expand discovery)
- Example 3: Invoke-MSGraphRequest translation patterns
- Example 4: Property cleanup patterns
- Plus: Complete end-to-end example (Compliance Policies)

**FR-005**: Troubleshooting section ✅
- Section "Troubleshooting API Discrepancies" with 8-point checklist
- Example 1: Missing $expand parameter causing incomplete data
- Example 2: 400 Bad Request due to wrong API version

**FR-006**: Fallback process ✅
- Section "Fallback Process for Missing PowerShell Reference"
- 5-step process: Check docs → Use Graph Explorer → Extensive testing (2 tenants, 5 resources) → Document assumptions → Monitor for updates

**FR-007**: Versioning strategy ✅
- Section "Versioning Strategy" documents commit tracking
- Example comment format showing PowerShell reference version
- Process for updating when PowerShell changes

**FR-008**: Replicate vs document behaviors ✅
- Section "PowerShell Quirks vs Intentional Patterns"
- Decision framework: What to replicate (property cleanup, $expand, API versions)
- What not to replicate (PowerShell-specific syntax, Windows paths)
- Marking convention: `// [POWERSHELL QUIRK]: <description>`

### Success Criteria Achievability

**SC-001**: 2-hour implementation time ✅
- Guide provides step-by-step process reducing discovery time
- Concrete examples accelerate pattern recognition
- Expected to reduce 8-hour trial-and-error to 2 hours

**SC-002**: 95% first-attempt accuracy ✅
- Comprehensive data extraction checklist prevents missing parameters
- Troubleshooting section catches common mistakes
- Validation process ensures correctness

**SC-003**: Zero API surprises ✅
- PowerShell analysis discovers undocumented behaviors upfront
- Examples show hidden requirements (e.g., $expand=settings)

**SC-004**: 30-minute onboarding ✅
- "Understanding Existing Implementation Patterns" section explains rationale
- FAQ addresses common questions
- Real-world examples provide context

**SC-005**: 50% code review reduction ✅
- Reviewers can verify against PowerShell reference
- Version comments enable quick validation
- Standardized patterns reduce questions

**SC-006**: Zero "why beta API?" questions ✅
- "When to Use Beta vs V1.0 API" section documents decision process
- Examples show PowerShell reference as source of truth

### Coverage Summary
