Find a Web site with direct customer ordering. Browse through some product descriptions and note the design of the dialog and the Web pages. What do you like and dislike about the design? Evaluate the Web site based on visibility and affordance. Does the site achieve an optimal balance between the number of page refreshes and the delay between page refreshes? Would your answer change if you were using a different computing device, a different network, or accessing the system at a different time of day?
