Analysis
Overall, we were pleased with our users' ability to navigate the interface. All the users accomplished all of the provided tasks correctly, and there were no errors in the prescribed or administered medications. The primary problems that our users faced were in locating context-dependent information such as patient allergies and in locating the correct buttons to activate the "Prescribe" and "Administer" interface elements.
User 1's troubles with finding the patient information while prescribing a new medication led us to consider the role of the patient information sidebar, and the value of context in our interface. Our eventual conclusion was that the patient information sidebar provided context which was valuable in any mode of the interface we were testing, and we decided to have the sidebar present and visible throughout all of the screens (adding consistency and context). This ensured that the patient allergy and history information was always visible to the doctor or nurse, which helped in the correct prescription of medication. User 1 also had interesting comments on the representation of responsibility in the interface.suggested that the interface should make the current user's scope of responsibility (as a doctor or nurse) clearer.
The first three users alike all stumbled in some way on the "Add Medication" form, indicating some need for updating the way the fields collect information. Our initial revision had the "Frequency", "Start", and "End" fields as free-form text boxes, but we quickly realized that a richer, more structured input method for these fields could reduce confusion.TODO: expand the analysis to take into accounts the notes for the six users.
Usability issues
Issue 1:
Users couldn't see patient allergy information when prescribing new medication
Fix: Make patient information sidebar visible at all times, providing consistency and context

The second round of iterations focused on the input format of the "Add Medication" form. Specifically, we As suggested in the studio section, we changed the format of this screen to an expandable pane, rather than a popup. We also switched from free-form text boxes to more structured inputs for the "Frequency", "Start", and "End" fields. For "Frequency", we supplied a drop-down with choices for the frequency, and for "Start" and "End", we supplied a date-time picker. This reduces confusion about the formatting of the text in those fields. We also added example values, colored light gray, to those fields to indicate the expected type of information, as shown below:
