Usability Method Exercise
Usability is often used to determine the effectiveness of new technology, in particular, EHR or EMR systems. Usability is measured by five key components.
In this assignment, you will evaluate the usability of a personal Health Record (PHR). Do a search on the internet for a free PHR application you can measure against the 5 usability components.
Once you have identified an application, register for it (choose one that is free) and develop a scenario that tests each component of usability defined below. You will want to focus the scenarios to measure the usability based on the adult population aged 60-75. You do not need to report your findings on the scenario; just develop the scenario that would test each component.
For example: Learnability asks the question, how easy is it for users to accomplish basic tasks with minimal training on the application? A scenario that could be used to measure this component is “Without reading any directions in the application, navigate through the PHR and find the section pertaining to medications and determine how easy it was to record medications for your entire family.”
Learnability – How easy is it for users to accomplish basic tasks with minimal training on the application?
Efficiency: Once users have learned the application, how quickly can they perform the basic level tasks?
Memorability: When users return to the design after a period of not using it, how easily can they remember how to do the same tasks?
Errors: How easy is it to perform an error, how is the user notified the action taken was undesirable, and how easy is it for the user to recover from the error?
Satisfaction: How satisfying is the user experience of the application?
Please Meet Criteria!
