Original study example
Compare two options using cost and quality scores. With equal weights, A scores 8 and 4 while B scores 5 and 9. Which has the higher weighted score?
Work through the example
A scores (8 + 4)/2 = 6; B scores (5 + 9)/2 = 7. B wins under equal weights on this chosen scale. This is not proof that B is always better: justify the scoring and test a different weight for cost before recommending an option.
