We use it across the entire organization. It enables us to bring together at the same time our various regional directors from different parts of the country. In doing so it saves us significant amounts of travel expense, etc.
One of the things it does very well is allow screen sharing so that we can work on the same materials at the same time.
Another thing it allows is for us to build relationships far more effectively than any other means except in person. It is prohibitively expensive for us to fly all of our regional directors to the same location more than once a year.
I'm not sure this is a Zoom issue, but one of the problems we periodically have is sound distortion. The only way we have been able to cope with it is to have everyone mute their mike until it is their turn to speak, or until they want to say something.
When using screen share with multiple choices I find that when I have finished a YouTube video presentation I want to go back to another element of screen share, such as a document, it is difficult to find precisely where to shut down the one presentation so that I can pick up immediately with the document on screen share. This might be more a YouTube issue, as it happens to me most of the time when I'm coming off a YouTube presentation.
Zoom is well suited for our particular situations, which is that we have regional directors in several different states. In order for us to meet together periodically, there is no better tool than Zoom. It also seems to work well whether some of us are on PCs and others are on iPhones, etc.
