🎯 Multi-Criteria Decision Analysis (MCDA) Framework
Framework Foundation
Our assessment methodology is based on established Multi-Criteria Decision Analysis (MCDA) principles, as outlined in academic literature by Triantaphyllou (2000) and Keeney & Raiffa (1993). This approach allows for systematic evaluation of complex policy impacts across multiple dimensions.
Five Assessment Criteria
📏
1. Scope
Coverage and Reach
Measurement: Population coverage, demographic reach, institutional span
Scale: 1-5 (Limited → Universal)
Example: HDB covers 78.7% of population = High score
⚡
2. Magnitude
Scale of Impact
Measurement: Economic impact, social outcomes, measurable benefits
Scale: 1-5 (Minimal → Transformative)
Example: CPF manages 67% of retirement adequacy = High score
🏗️
3. Durability
Long-term Sustainability
Measurement: Policy longevity, institutional stability, adaptability
Scale: 1-5 (Short-term → Multi-generational)
Weight: 2x multiplier (emphasized for long-term focus)
🔄
4. Adaptability
Flexibility and Evolution
Measurement: Policy modifications, responsive changes, innovation integration
Scale: 1-5 (Rigid → Highly Adaptive)
Example: GST rate adjustments show adaptability
🌐
5. Cross-referencing
International Benchmarking
Measurement: Global rankings, comparative performance, best practice recognition
Scale: 1-5 (Below average → Global leader)
Sources: OECD, World Bank, UN, WEF rankings
Scoring Methodology
| Score | Performance Level | Description | Examples |
|---|---|---|---|
| 5.0 | Exceptional | Global leader, transformative impact | HDB Housing, EDB Economic Strategy |
| 4.0-4.9 | Excellent | High effectiveness, comprehensive coverage | CPF System, SkillsFuture |
| 3.0-3.9 | Good | Solid performance, adequate coverage | Healthcare schemes, Education policies |
| 2.0-2.9 | Moderate | Basic effectiveness, room for improvement | Emerging policies, pilot programs |
| 1.0-1.9 | Limited | Minimal impact, narrow scope | Early-stage interventions |
📊 Quantitative Scoring Criteria
Scientific Basis for Score Assignment
Each dimension uses empirically-validated quantitative thresholds based on international research and benchmarks. This ensures objective, reproducible scoring that can be scientifically defended.
📏
Scope: Coverage Thresholds
| Score | Coverage Threshold | Scientific Basis | Singapore Example |
|---|---|---|---|
| 5.0 | ≥80% population | WHO Universal Coverage Standard | HDB Housing (78.7% → 4.8 score) |
| 4.0-4.9 | 60-79% population | World Bank High Coverage | CPF Mandatory Coverage |
| 3.0-3.9 | 40-59% population | Moderate Coverage Standard | SkillsFuture Uptake (40%) |
| 2.0-2.9 | 20-39% population | Limited Targeted Coverage | Housing Grants (25% eligible) |
| 1.0-1.9 | <20% population | Minimal/Pilot Coverage | R&D Tax Incentives (5%) |
⚡
Magnitude: Economic Impact Thresholds
| Score | GDP Impact OR Improvement | Scientific Basis | Singapore Example |
|---|---|---|---|
| 5.0 | ≥5% GDP OR >50% improvement | IMF Macro-economic Significance | HDB: 20% of GDP (housing sector) |
| 4.0-4.9 | 2-4.9% GDP OR 25-50% improvement | World Bank Major Impact | CPF: 3.2% of GDP contributions |
| 3.0-3.9 | 0.5-1.9% GDP OR 10-24% improvement | Measurable Economic Effects | GST: 1.8% of GDP revenue |
| 2.0-2.9 | 0.1-0.49% GDP OR 5-9% improvement | Limited Measurable Impact | SkillsFuture: 0.2% GDP investment |
| 1.0-1.9 | <0.1% GDP OR <5% improvement | Minimal Economic Impact | Small pilot programs |
🏗️
Durability: Institutional Longevity
| Score | Longevity Threshold | Scientific Basis | Singapore Example |
|---|---|---|---|
| 5.0 | ≥30 years OR multi-generational | Institutional Permanence Theory | HDB Act (1960-present: 65 years) |
| 4.0-4.9 | 15-29 years OR one generation | Cross-electoral Cycle Survival | CPF (1955-present: 70 years) |
| 3.0-3.9 | 5-14 years OR medium-term | Government Change Survival | GST (1994-present: 31 years) |
| 2.0-2.9 | 2-4 years OR short-term | Electoral Cycle Dependent | Temporary budget measures |
| 1.0-1.9 | <2 years OR pilot status | Experimental/Crisis Response | COVID-19 support packages |

Cross-referencing: International Rankings
| Score | Global Ranking | Scientific Basis | Singapore Example |
|---|---|---|---|
| 5.0 | Top 5 globally (95th+ percentile) | WEF Global Leadership Standard | Housing (Rank #1 homeownership) |
| 4.0-4.9 | Top 6-15 globally (80-94th percentile) | Advanced Economy Standard | CPF retirement (Rank #8) |
| 3.0-3.9 | Top 16-30 globally (60-79th percentile) | Above OECD Average | Education (Rank #21 OECD) |
| 2.0-2.9 | Rank 31-60 (40-59th percentile) | OECD Median Range | Some healthcare metrics |
| 1.0-1.9 | Below rank 60 (<40th percentile) | Below Average Performance | Areas needing improvement |
🔬 Example: HDB Housing Scope Score Calculation
- Data Collection: 78.7% coverage (Singapore DOS, 2023)
- Threshold Assessment: Falls in 60-79% range = 4.0-4.9 score
- International Context: Singapore ranks #1 globally = exceptional performance
- Final Score: 4.8/5.0 (high-end due to near-universal + global leadership)
- Scientific Justification: Verified statistics + WHO universal coverage principles
