The present invention provides a system and method for facilitating workplace utilization and occupancy management using mobile devices. The present invention integrates a workplace management component, a sensor or location-based management system and an actual use of space analysis engine to provide significantly enhanced data accuracy regarding use of space, which improves system effectiveness and affects individual behavior. In one embodiment, the location-based management component incorporates global positioning system and/or near-field communication system technologies to determine when a user with a suitable mobile communications device is approaching a real estate resource where a reservation has been made, and in that event, issuing a notification to the user' s device prompting action connected to the reservation. By affecting individual behavior, the system produces even greater data accuracy and improved control and management of resources.
