Chapter 16: Propensity Analysis (AHP)
A decision-support tool using AHP (Analytic Hierarchy Process). Access by clicking “Propensity Analysis” in the sidebar.
16.1 What Is AHP?
AHP is a decision-making methodology for comparing and evaluating multiple alternatives based on multiple criteria (evaluation dimensions). It quantifies relative importance between criteria through pairwise comparison, enabling objective scoring.
16.2 Four Steps
Switch between four steps using tabs at the top:
- Setup → 2. Weighting → 3. Evaluation → 4. Results
16.3 Step 1: Setup
Setting Evaluation Dimensions (Criteria)
Define the criteria for evaluation.
Operations:
- Enter criteria names in the text input (e.g., “Creativity”, “Logic”, “Execution”, “Empathy”, “Strategy”)
- Click “+” or press Enter to add
- Remove unwanted criteria with the trash icon
Default Criteria:
- Logic & Analysis
- Strategic Vision
- Creativity
- Empathy & Communication
- Execution
Setting Targets/Actions (Alternatives)
Define the targets for evaluation.
Operations:
- Enter target names in the text input (e.g., “Plan A”, “Plan B”, “Status Quo”)
- Click “+” or press Enter to add
- Remove unwanted targets with the trash icon
Default Target:
- Current Thinking Pattern
After setup, click “Next: Weighting” at the bottom.
16.4 Step 2: Weighting
Set relative importance of each evaluation dimension through pairwise comparison.
Screen Display:
- Pairs of criteria are displayed with sliders
- All pairs are compared in sequence (N criteria → N×(N-1)/2 comparisons)
Slider Operations:
- Center (0): Both criteria equally important
- Move right: Right criterion more important (up to 9×)
- Move left: Left criterion more important (up to 9×)
Dynamic Text Display:
Moving the slider shows text like “Creativity is 3.0 times more important than Logic.”
Calculation Method: Geometric Mean Method is used. Geometric mean of each criterion is calculated from the comparison matrix and normalized to derive weights.
After all pairs are compared, click “Next: Evaluation.”
16.5 Step 3: Evaluation
AI automatically evaluates each target on each criterion with a 0-10 score.
Operations:
- Click the “Run AI Analysis” button (with brain icon)
- AI begins analysis (~2 seconds)
- During processing, brain icon pulses and progress bars appear on each target card
- After completion, each target card shows all criteria scores (0-10) as horizontal bar graphs
Reading Scores:
- 0-3: Low (low capability/aptitude for that criterion)
- 4-6: Moderate
- 7-10: High (high capability/aptitude for that criterion)
After all target scores are displayed, click “Next: Results.”
16.6 Step 4: Results
View analysis results with three types of charts.
Propensity Profile (Radar Chart)
Visualizes each target’s criteria scores as polygons.
- Each axis represents one criterion
- Center (0) to perimeter (10) shows score magnitude
- Multiple targets overlap for easy comparison of tendencies
Dimension Importance (Horizontal Bar Chart)
Importance percentage of each criterion derived from Step 2 weighting.
- Totals 100%
- Longer bars indicate more important criteria
Overall Score (Horizontal Bar Chart)
The final ranking.
Formula: Overall Score = Σ (Criterion Score × Criterion Weight)
Each target’s overall score is displayed as a bar graph, with the highest-scoring target being the recommended choice.
16.7 Troubleshooting
| Issue | Cause and Solution |
|---|---|
| Results not displayed | Verify Steps 1-3 are all completed. Specifically, “Run AI Analysis” in Step 3 is required |
| Radar chart is triangular | This is normal when only 3 criteria are set. Setting 4+ criteria makes it more readable |
| “Next” button is disabled | Current step inputs are incomplete. Check that at least one criterion and one target are set |
| All scores are the same value | AI evaluation may be uniform. Make target descriptions more specific and re-run |
