Create a Decision Matrix

The first concept is sometimes used as a baseline concept Create a Decision Matrix

Rate the Concepts

1 Much worse than baseline 2 Worse than baseline 3 No difference from baseline 4 Better than baseline 5 Much better than baseline Rate the Concepts

+ Better than ( + scored as 1) 0 Same as (0 scored as 0) – Worse than (– scored as -1) Alternate Rating System Any numeric scale (e.g., 1 – 10) Rate the Concepts

Rating x Weight Factor = Weighted Score 4 Rate the Concepts
