User 5 was a female with emergency medical training. She accomplished both user roles' tasks quickly and easily, but had two concerns that hindered her progress. First, as with many of our users, she found the "frequency" input unclear, but when it was replaced with a dropdown menu she found it much more understandable. Second, she felt that she wanted to ensure that there was some indication of the patient's immediate medication history in the sidebar so that it could be accessed from anywhere, especially in case she needed to find out if the patient had received any medication prior to ICU admission.

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.

The second round of iterations focused on the input format of the "Add Medication" form. 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:
