Lab 3 – Concept Screening and Scoring
When deciding on a final design, using a screening and scoring matrix allows the group to choose baised on whatever you deicide is important for the AEV. The group made a screening and scoring matrix and choose the group design from the four designs made in Lab 01. This was from then on, the base of the final design we will use for testing.
