Heuristic Principle | Expert Comments |
|---|---|
5. Help Users Recognize, Diagnose, and Recover From Errors. | “No error messages. I do not know why I can’t retrieve any patients.”“Doesn’t seem to do error checking.”“The system doesn’t help users recognize errors.”“In the Pharmacy Order Code lookup menu, the system displays one record when you enter ‘tylenol’ whereas it shows multiple records when you type in ‘acetaminophen’. Does this mean the user has to use a generic name instead of a brand name for lookup?”“The system doesn’t do error checking or provide feedback.” |
6. Error Prevention | “I entered age of 655 by mistake when I meant to enter 65. These kinds of errors should be prevented.”“Can’t navigate between the main menu and the criterion menu.”“I was able to enter an age of 800.”“System doesn’t seem to prevent errors.” |
10. Help and Documentation | “No help.”“There is no help function.”“If you don’t know what you are doing, then you are completely stuck!” |
