In the initial prototype, the user was presented with the following dashboard.  Tabs on the side provide the user the ability to filter the result set (not implemented in the first paper prototype).  The center column provides a list of jobs separated into 3 categories: unassigned, assigned, and recently completed.  Jobs have the ability to be clicked ("focused"), or starred.  The rightmost column shows the currently selected or focused job.  A description of the job, the ability to mark it complete, assign it to a worker, and create updates on the focused job.

The user is able to star jobs in the center column by clicking on the star to the left of the job title.  The UI is simply updated to reflect the starred job.

Users can assign a focused job to a list of workers.  The assignement is done in the right column by clicking the dropdown list of users.

When a user assigns a job to a particular user, the UI is updated to reflect this by showing the assigned worker on the right side of the assignment widget.

Notifications are presented to the user in the upper left.  The notification widget is updated with a count of the number of notifications.  In the paper prototype, the mechanic created an update on a particular job (see the focused job update section), which created a new notification in "real time".

The address book, opened from the main dashboard, presents the user with an unfiltered alphabetically ordered listing of contacts.  The user has the affordance of searching (with autocomplete and auto-filtering), and scrolling.  The paper prototype did not support scrolling, however.

By typing the beginning of a search term, the results are dynamically updated to reflect the best fit results.

The second version of the paper prototype does not have a job selected by default.  This forces a user to select a job before any information is displayed in the right column.  The rest of the initial dashboard is unchanged.

The second version paper prototype gives feedback to the user as to which job is currently focused.  An arrow on the right of the focused job as well as an indicator on the left of the focused job is displayed.

The second version of the paper prototype includes a new way of starring jobs.  The updated job information includes the star in the upper right of focused job.  This allows users two places to acheive the same functionality of marking a job as "starred".

The second version of the paper prototype includes the ability to filter results based on the left-most column.  When the tab in the left column is selected, the center list is filtered to list only the matching jobs.  Jobs may then be selected as previously.
