How the Dominance Rule Works
The system looks at all the impact levels (High, Medium, Low) within a cell and applies the following logic:
1️⃣ If one impact level makes up at least 33% (one-third) of the total impacts, the cell takes that color.
2️⃣ If no single level reaches 33%, the system defaults to the highest impact present in the cell.
Examples of How Colors Are Determined
Impact Levels in a Cell | Total Impacts | Calculation | Final Color |
1 High + 2 Medium | 3 | High (33%) → Meets threshold | 🔴 High |
1 Medium + 2 Low | 3 | Medium (33%) → Meets threshold | 🟠 Medium |
1 Medium + 3 Low | 4 | Low (75%) dominates | 🟢 Low |
2 High + 2 Medium + 1 Low | 5 | High (40%) is the strongest | 🔴 High |
1 High + 1 Medium + 1 Low | 3 | No level reaches 33%, default to highest | 🔴 High |
0 High + 3 Medium + 2 Low | 5 | Medium (60%) dominates | 🟠 Medium |
Why This Rule?
- Ensures major impacts aren’t overshadowed by minor ones.
- Helps identify critical areas requiring attention.
- Provides a clear and fair way to assess change saturation.
📌 Key Takeaway:
If an impact level is strong enough (at least one-third of total impacts), it determines the color. Otherwise, the highest impact level present sets the color.
