Design Testing Matrix
Fill in the optimal row based on the criteria and constraints from the article.
Fill in the incubator information for A and B as you read about them.
Use this information to fill in the incubator A information on the design testing matrix.
After you complete the design testing matrix for Incubator A, consider how the features of Incubator A compare to the optimal solution based on criteria and constraints. Use only Incubator A and the optimal solution row to answer the following questions.
