UX and Task Efficiency

Hier habe ich einen recht guten Beitrag für Euch, liebe THS-Leser: Evaluating UX by Measuring Task Efficiency.

Efficiency, or the amount of time an expert user takes to complete a task, can have a direct impact on the bottom line. A few seconds off a call center task can save hundreds of thousands of dollars in a year. However, what is the impact of efficiency on consumers? CogTool is a software product developed by Dr. Bonnie John’s lab at the Human Computer Interaction Institute of Carnegie Mellon University. CogTool evaluates a design with a predictive human performance model to predict the time it will take for an expert to complete a task.

Actions may include reading text on a screen, moving the mouse, moving the hand from the mouse to the keyboard, and typing.
