Design Step 3
In this step, we evaluated our three possible design concepts. To do this, we created a decision matrix. We created five evaluation criteria, which we weighted in our decision matrix. All of the weights added up to 1. We then gave each concept a score from 1 to 10 for each value, multiplied this score by its weight, and added up the resulting values. This created a numeric evaluation of each concept. Although the results of this decision matrix are not binding, they helped us decide on a concept. In the end, we decided to use Concept 1, the winner, but with some alterations.
Below is our decision matrix.

Reflection
One thing that went very well during this step was our evaluation of the results of the matrix. All the values were very close, but we were able to use them in conjunction with our own ideas to come up with a final concept. Another thing that went well was our time management. We were able to finish the decision matrix with plenty of time to spare for evaluation.
One thing that we struggled with was our initial understanding of the requirements. We had never seen a classification scheme before, and we were confused by the concept. However, after we figured out what we were supposed to do, the process ran smoothly. Another thing that did not go as well was our distribution of the weights. It took us a long time to decide how we wanted to distribute them, but we came up with a good system.
During this step, I learned how to choose between alternative concepts and polish the idea of a final concept.
