Risk-Based Testing Prioritization Rubric: Focus Your Efforts
Use this rubric to prioritize testing efforts on the highest-risk areas. This minimizes critical defects in production.
Risk-Based Testing Prioritization Rubric:
1. **Likelihood of Failure (1-5):** (1=Very Low, 5=Very High)
2. **Impact of Failure (1-5):** (1=Minor, 5=Catastrophic)
3. **Priority Score:** Likelihood x Impact
4. **Testing Priority:** (High=15-25, Medium=8-14, Low=1-7)
