Employee Directory allows you to keep track of employees in your company. You can look for employees by name, view the details of an employee, add an employee to your Contacts, and navigate up and down the Org Chart by clicking the employee’s manager or any of his/her direct reports.
The application comes with a sample dataset to provide an "out-of-the-box" experience. Click the Synchronize button on the home screen to access the Synchronization screen and provide the endpoint URL to your own data synchronization dataset.
Technical details on using and synchronizing your own data are available here: http://employeedirectory.org/app
