Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities.
The ACD is a modeling tool that was developed in 1960 following the flow diagram method of K.D. Tocher. [2] It pertains to the activity-based paradigm of system modeling, as opposed to process-oriented or event-based paradigms.

This view includes sequence diagrams, activity diagrams and state machine diagrams. UML models can be exchanged among UML tools by using the XML Metadata Interchange (XMI) format. In UML, one of the key tools for behavior modeling is the use-case model, caused by OOSE. Use cases are a way of specifying required usages of a system.
Use case diagrams are used to identify the actor (users or other systems) and the processes they perform. System sequence diagram: A system sequence diagram (SSD) is a picture that shows, for a particular scenario of a use case, the events that external actors generate, their order, and possible inter-system events.

When working with activity-centered design, the designers use research to get insights of the users. Observations and interviews are typical approaches to learn more about the users' behavior . By mapping users' activities and tasks, the designer may notice missing tasks for the activity to become more easy to perform, and thus design solutions ...
