Design Concepts: Screening and Scoring

 Design Concepts: Screening and Scoring

The purpose Lab 05 was to use screening and scoring concepts to determine success criteria. This allowed the team to discuss the most important factors that should be focused on with the AEV. Concept screening was initially used to eliminate the least important criteria. Concept scoring was then used to shine light on the most important categories that the team should focus on when designing the AEV.

From this lab, the team concluded that balance was the sole focus of the designs that would be chosen. Several of the group’s designs will be combined to create better rounded AEV. The key takeaway from this lab was how important it is t determine success factors when working on a project with time and economic constraints.
