Explain a design choice using stated priorities
The idea
Define each measure and whether a larger value is better before assigning weights.
Step by step
- Define each measure and whether a larger value is better before assigning weights.
- Apply the same stated weights to every option, then compare the resulting scores.
- Report ties and limitations honestly; a score reflects this model, not a universal best design.
Example
Design A: performance 90, resource score 50. Design B: performance 70, resource score 80.
The stated rule is score = × performance + × resource score. Higher values are preferred for both measures. Which design has the higher score, or are they tied?
Answer
A tie under this scoring rule
A scores × 90 + × 50 = 74. B scores × 70 + × 80 = 74. This rule gives a tie under this scoring rule; changing the weights could change the decision.
