Ontology Scoring

Score components

1. Resource breadth: how many resources affected
2. Propagation / Tier: how likely it amplifies at scale
3. Severity: operational seriousness
4. Confidence: confidence of detection or impact claim
5. Fix effort: how hard it is to remediate safely (optional)

Suggested score formula

Let:

• R = number of impacted resource categories (1–8)
• T = tier (1–4)
• S = severity weight: {note:0.5, low:1, medium:2, high:3, critical:4} (tune as you like)
• C = confidence (0.0–1.0), default 0.6 if unknown
• E = effort weight (1–3), default 2 if unknown (1 easy, 2 moderate, 3 hard)

Then:

ImpactScore (0–100)

base = (10 * R) + (12 * (T - 1)) + (8 * S)
adjusted = base * (0.6 + 0.4*C)
final = adjusted * (1.1 - 0.1*E)
clamp to 0..100

Why this works:

• Tier matters a lot (amplification)
• Breadth matters (multi-resource waste is more systemic)
• Confidence prevents low-quality signals from dominating
• Effort gently penalizes “hard fixes” so roadmaps balance wins vs rewrites

Example interpretation buckets

• 0–25: opportunistic cleanup
• 26–50: backlog priority
• 51–75: plan and track
• 76–100: needs architectural attention
