Advanced Notations The contents of an activity diagram may be organized into partitions (swimlanes) using solid vertical lines. Advanced Notations Nested Activity Diagrams. An activity diagram is a flowchart that outlines all the activities performed by a system. As a result, it’s a useful way for a non-technical audience which can include key stakeholders to visualize your system. You can either show the sub-graph inside of the activity state or let the activity state refer to another diagram Nested Activity Diagrams A use case diagram is often used as a top-level overview of how users and systems interact. Advanced Notations An activity state may reference another activity diagram, which shows the internal structure of the activity state by having a nested activity graphs. Advanced Notations Guard conditions can be used to show that one of a set of concurrent threads is conditional. Basic Notations Start State Activity State Decision (branch) Synchronisation bar Stop/End State Concurrent thread Alternative thread Transition. 
Business Modelling This example is a proposal process, taken from an organization that sells telecom network solutions. 
Historically, activity diagrams have mostly been used in the business process modeling domain but are also useful in system modelling.
Activity Diagram In its basic form, an activity diagram is a simple and intuitive illustration of what happens in a workflow, what activities can be done in parallel, and whether there are alternative paths through the workflow. Terry Winograd, “Bringing Design to Software”, Addison Wesley, Stanford University and Interval Research Corporation, With John Bennett, Laura De Young, and Bradley Hartfield, ISBN: 1-0. It’s where you stand with a foot in two worlds-the world of technology and the world of people and human purposes-and you try to bring the two together. Thoughts to Ponder … If you reuse code, You'll save a load, But if you reuse design, Your future will shine. It has to be used together with a process in a development environment. However, most students use UML 1.4 which is sufficient for most academic projects. 
Open Specification by OMG (Object Management Group). Together with the use case diagram and the state diagram, it belongs to the group of so-called behavior diagrams.

Introduction to UML UML is a language for visualising, specifying, constructing and documenting the artifacts of a software intensive system. An activity diagram is a means of expression of the Unified Modelling Language (UML), with which temporal processes within a system are described.Why Model? Captures Processes Enhances Communication Manages Complexity Defines Architecture Enables Reuse.Keywords Business modelling Activity state Transition Triggerless transition Synchronisation bar Start state Stop/End state Branch Guard Fork Join Concurrent thread Alternative thread Conditional thread System modelling.
