Table 1
This matrix represents the relationship between the prototype design requirements and the user needs defined in the task. The user needs that are addressed the most with these design requirements are the convenience, reliability, and effectivity. These user needs are also rated as some of the most crucial from our primary research, as indicated in our pairwise comparison chart from our problem definition review. The requirements that are weighted the most important are: Energy Use, Stopping Precision, Time Takes to Stop, and the Mass. The correlation matrix helps us determine design standards and allows us to make decisions as to which requirement is more necessary if a conflict should arise. While these design tradeoffs shouldn’t need to occur, the importance value will help solve the issue as to what the focus of the prototype should be. This will allow us to create a better scored verification test, and allow the weighting of the scores to be altered based off of the requirement importance from the correlation matrix. The most important verification tests will be testing the Energy Use, Stopping Precision, Time Takes to Stop, and the Mass.
