Users In Iteration #1, users felt bombarded with text/information when they first looked at the application.
So when the application is first opened in Iteration #2, no repair job entry in the middle panel is selected and so the right panel (which provides details of a selected job) is empty (with just the text "No job selected" showing in the right panel). This approach not only spares the user from the initial text/information overload, but it also emphasizes the connection between the middle/right panels by conveying to the user that nothing is displayed in the right panel since "No job selected".

Users In Iteration #1, users did not understand the connection between the middle and right panels.
In addition to the aforementioned fix, Iteration #2 features new UI components that better indicate that the content in the right panel are details of the job selected in the middle panel. In particular, we added a vertical rectangle at the left of a selected job entry to indicate which job has been selected and an arrow at the right of a selected job entry to indicate where more information about the job can be found.

Users had difficulties finding how to mark a task as important.
Users attempted to find the "Star" widget in the right panel to no avail. We realized this was because there was a "Mark Completed" button in the right panel and so users may have thought a "Mark Important"/star button was also located in the right panel. To fix this, in Iteration #2, we added a "Star" button/widget to the right panel.

Users wanted to use the tabs on the left.
During the first round of user testing, users would often click through the tabs in the left panel when searching for a particular job's details. However, we had not implemented this functionality for Iteration #1's Paper Prototype. So for Iteration #2, users were able to search through jobs via clicking through the tabs in the left panel.
