چکیده
Usability subjects’ success with and preference among Open, Menu-based and Directed Strategy dialogs for a call routing application in the consumer retail industry are assessed.

Preference and task completion scores were highest for one of the Directed strategies; another directed strategy was least preferred and the open strategy had the lowest task completion score.
