Full Pugh Analysis


Concept 5 was selected as it had the most positives with the least negatives. This makes sense as it was generated as a composite between one and three, combining the good features found within each of those concepts while eliminating some of the not so good features and then submitted to the same pugh analysis. It is believed by the group that this concept will best meet the end goals of this project.
