Consider this simplified risk table for features:

Feature A: Impact=5, Likelihood=4
Feature B: Impact=3, Likelihood=6
Feature C: Impact=4, Likelihood=2


Which feature should be tested first based on risk?
AFeature B
BFeature A
CFeature C
DAll features equally
Step-by-Step Solution
Solution:
  1. Step 1: Calculate risk for each feature

    Risk = Impact x Likelihood.
    Feature A: 5 x 4 = 20
    Feature B: 3 x 6 = 18
    Feature C: 4 x 2 = 8
  2. Step 2: Identify highest risk

    Feature A has the highest risk score (20), so it should be tested first.
  3. Final Answer:

    Feature A -> Option B
  4. Quick Check:

    Highest risk = Feature A (20) [OK]
Quick Trick: Multiply impact and likelihood to find highest risk [OK]
Common Mistakes:
  • Choosing feature with highest likelihood only
  • Ignoring impact in calculation
  • Testing all features equally without prioritization
