This article will describe the usage for the decision action.
The decision action is more of a convenience action than a practical action. The decision action is used to help highlight the point in a flow chart where a decision is being made. It is possible for any action in a flow chart to contain conditional branches. This means that the decision action is not needed unless trying to show more detail about the flow chart.
Here is an example of two flow charts that are essentially the same except one has a decision action and the other does not. They both achieve the exact same task, except the flow chart with the decision action makes the steps more apparent to the viewer.
