Abstract: An office system for improving workplace resource usage includes multiple application instances implemented on multiple mobile electronic communication devices, associated with office occupants. The application is configured to determine a device user's location and, to execute an action based on the device user's location. The application may also access the user's calendar. In response to this data, the application may engage in communications and tasks to improve efficiency, such as asking the user if they would like cancel a meeting that the user may be unable to make, as well as affirmatively reserving and releasing office resource such as meeting rooms when user context so indicates.
