For this assignment you are to develop 5 usability scenarios that you think are most appropriate to use if you were to conduct an observational usability study on the use of the PHR in an adult population ages 3055. Please address the following items in your scenarios:
-
How fast can the learner use the PHR system (Ease of learning)?
-
How fast can the learner accomplish tasks using the PHR? (Efficiency of use)?
-
How effectively can the user learn the PHR system upon several different uses? (Memorability)
-
How often do errors occur, how serious and what do users do to manage the error? (Error frequency and severity)
-
How much does the user like using the system? (Subjective Satisfaction)
An example of a usability scenario may look like this:
You are developing your PHR for the first time and you would like to enter all medications used by all 5 members of your family. Navigate through the PHR to find a section on medications and determine if you are able to record all medications used by each member of your family.
To complete this assignment, you will need to develop 5 different usability tasks or scenarios that address the 5 items listed above.
See the link below for sample questions on a usability study questionnaire CSUQ developed by IBM http://drjim.0catch.com/usabqtr.pdf related to subjective satisfaction, but remember to develop your own scenarios specific to the PHR system you chose.
Submit your assignment as an attachment to Learning Activity 2.2.
