A Dynamic Dashboard is one that is set to refresh automatically. The refresh interval is user-definable. This means that it is possible to have information that is virtually real-time.
For example, a shop floor manager with multiple POS till points can see at a glance what the takings at each till point is, accurate to the last 5 minutes.
A Sales Manager can see what the total value of orders for the day is for each Sales Rep accurate to the last 10 minutes.
