Formulate an improved solution to the design problem.

Formulating should include

•    revisiting the solutions proposed
•    proposing an improved solution(s), based on data acquired
•    justifying how the improved solution better meets the criteria
•    testing the improved solution.

Process/Skill Questions:

•    Why should one revisit the solutions proposed when formulating an alternate solution to the problem?
•    How might the data acquired in the test influence the formulation of an alternate solution?
•    Why and when should stakeholders’ feedback be considered?
•    What factors might help justify an alternative solution as optimal?
