Undertake a final evaluation of the design that has evolved from the walkthrough in Project Part II.  You may use a GOMS technique, think-aloud protocol with scenarios or focus group.  Write up the evaluation findings and use them to refine the final design.  Items to be handed in include:

1) Evaluation description and findings.  I want to know how you conducted the final evaluation, why you chose the technique you did, and what came out of the evaluation in terms of refining the design concept.
2) A description and visual depictions of the final interface design.
3) The "design rationale"--that is your reasons for the important features of your design.  The reasons should be tightly linked both to the users and their needs and the evaluation techniques used at different stages.
