This workflow diagram provides a visual representation of the steps involved in a particular process. It outlines the sequence of activities, the resources needed, and the decision points along the way. The diagram can be used to identify potential issues or bottlenecks in the process, as well as to identify
Activity diagrams are graphical representations of workflows of stepwise activities and actions with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes, as well as the data flows intersecting with the related activities. "Object nodes hold data that is input to and output from executable nodes, and moves across object flow edges. Control nodes specify sequencing of executable nodes via control flow edges." In other words, although activity diagrams primarily show the overall control flow, they can also include elements showing the data flow between activities through one or more data stores.
