1. Selecting a Solution Path Engineering Design and Development

2. Selection Process 1.Create a decision matrix 2.Rate the concepts 3.Rank the concepts 4.Combine and improve the concepts 5.Select top concept(s) 6.Reflect on the results

3. Create a Decision Matrix Problem: Lessen premature death of Red Drum due to mouth infections in the lower Laguna Madre of Texas 7

4. 7 Create a Decision Matrix Problem: Lessen premature death of Red Drum due to mouth infections in the lower Laguna Madre of Texas

5. Create a Decision Matrix

7. The first concept is sometimes used as a baseline concept

8. Create a Decision Matrix

9. 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

10. 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)

11. Rate the Concepts

12. 4

13. Rating x Weight Factor = Weighted Score 4
