UML Activity Diagram. Design Elements
UML Activity Diagram is a type of Behavior Diagrams that graphically describes decomposition of the some activity on the components.
Activity Diagrams are used in modeling of business processes, technological processes, sequential and parallel computations.
UML Activity Diagram allows to show the sequence, branching and synchronization of processes.
To design UML Activity Diagrams use the following shape types:
- rounded rectangles to describe the actions;
- diamonds to describe decisions;
- bars to represent the start or end of the activities that occur at the same time;
- black circle to indicate the start of the workflow;
- encircled black circle to indicate the end of the workflow;
- arrows to represent the order in which activities happen.
Activity Diagrams were a specialized form of the State Diagrams in UML 1.x. In UML 2.x, the Activity Diagrams were reformed and now are based on Petri net-like semantics that allows to model a lot more situations.
The Rapid UML Solution for ConceptDraw DIAGRAM contains 13 vector stencils libraries with 393 interactive shapes that you can use to design your UML diagrams.
To design an Activity Diagram use the UML Activity Diagram library.
UML Activity Diagram library contains 37 shapes:
- Object

ConceptDraw Rapid UML solution provides UML Activity Diagram library of vector stencils for activity diagram design elements like rounded rectangles of activities, diamonds of decisions, bars of the start (split) or end (join) of concurrent activities, black circle of the start (initial state) of the workflow, encircled black circle of the end (final state), etc.
Use UML Activity Diagram library to draw your own activity diagrams that show the business and operational stepwise workflows of components in your system.
All libraries for creating UML diagrams are available inside the ConceptDraw DIAGRAM Templates and samples are located in the Rapid UML section of ConceptDraw STORE.

Process mapping helps with sharing business results and reorganizing workflow. In almost every case, after creating a sales process flowchart the steps that are redundant become obvious for a manager. It's easy to find a flowchart examples that will help in developing one for your business.
This sales process flowchart consists of a sequence of steps that represent a simple sale process. Each step is shown graphically by a rectangle representing processing steps or an activity, or a diamond representing a decision. These rectangles are linked by arrows, that indicate the direction of the sales workflow. ConceptDraw Sales Flowcharts solution delivers a the full set of classical flowchart notation symbols, along with sales-related icons and pictograms.
