Assess the design.

Assessment should include
•    comparison of criteria and constraints to model
•    level of accuracy of the desired outcomes.

Process/Skill Questions:

•    How does one test the design’s ability to solve the problem?
•    How many times should a prototype be tested? 
•    What is data? Why is it important?
•    What kind of data can be gathered from testing the prototype?
•    How can the data be assessed to form an opinion about the success of the prototype? Does the model or prototype meet all criteria? Does it meet all constraints?
