Instant Messaging (IM), allows for quick communication between two or more workers. Many businesses fail to see the benefit of IM, which allows for quicker information exchange when phone or email might not work. Workers can broadcast a question to a group of workers, such as an engineering department, in order to get a quick response. This method has the benefits of both speed and reducing email clutter. Many IM applications also include presence as well, which show the status of a worker’s availability in real time. IM can also be tightly integrated with other components of Unified Communications to allow for one-click control over multiple applications. When speed and responsiveness are critical, IM can transform the way businesses communicate, particularly in multi-location or segmented office environments. For an example of this application, see this short video.
