These additional capabilities include branching, parallel flow, swimlane, etc.Before drawing an activity diagram, we must have a clear understanding about the elements used in activity diagram. 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. I previously created a use case diagram to get a rough idea of what actions were needed. Alternatively, there is another way of presenting an activity diagram.

Activity diagram is a kind of UML diagram that shows flow of control from activity to activity. There is a toolbox that contains a range of elements, relationships and Patterns for creating the models. The tasks that can be performed in parallel should be kept parallel to each other (vertically). draw.io can import .vsdx, Gliffy™ and Lucidchart™ files . 1. Compared to a sequence diagram, which could be perceived to have a similar purpose, an activity diagram with partitions focuses on how you divide responsibilities onto classes, while the sequence diagram helps you understand how objects interact and in what sequence. Usually, the relationships are the sequences that take place in the activities. You may have to adjust the sequence a number of times until you get it right.
