Activity Definition

Let us define Activity

What does activity mean? What are good examples of activities in modeling? And do you model activities only with BPMN? Please read it here!

Definition of Activity

Dragon1 defines an activity as the behavior or action of a particular kind, done as work or for pleasure, alone or in a group, by humans, animals, robots, or systems.

An activity can be decomposed into tasks or seen as a major task. In the context of an organization, company, business, or enterprise, activity is considered most important.

The core purpose of activity monitoring is to generate economic gain or profit. By understanding and optimizing these activities through activity diagrams, businesses can improve cash flow, increase profitability, and effectively meet the needs of their target market.

The shape for activity is a geometric rectangle.

An example of activity is: 'making coffee', 'camping', or 'printing a sculpture'. Activities are normally part of functions and processes. A function group's activities focus on realizing the same goals. Processes structure this sequence of activities to achieve specific business goals.

Every day in every organization, many business activities occur. To manage and structure business activities, we often use two elements: business function and business process.

A business activity is any activity undertaken with the primary purpose of realizing business goals, such as making a profit.

For instance, sales activities are part of the business function 'Sales Management'. The business process of 'Closing a Deal' contains a few sales activities, but may also contain business activities from the business function 'Legal Management'.

You can model activities, functions, and processes on Dragon1. We have also extended ArchiMate Modeling Language with 'Activity'. ArchiMate previously included 'Activity' as an element, but it was removed when this standard was handed over to the Open Group. Dragon1 considers an activity to be the most important element of an organization. We use a circle as a shape for activity in ArchiMate.

Example of Activity

Here you see an example of Activity diagram in ArchiMate.

You see two business functions, 'Sales Management' and 'Legal Management', one business process, 'Closing the Deal', and four business activities. A business function groups activities, and a business process structures the order or flow of activities. You see, activity is a geometric circle here.

Creating Examples of Activities

Do you want to create Activity Diagrams yourself? Creating activities meaning; visualizing building blocks for modeling workflows and processes, etc. When designing activities, it is important to consider objectives, participants' needs, and the context in which these activities will take place.

Please note that, in BPMN, an activity is a generic term for work, including both atomic tasks and decomposable sub-processes. Also, the shape is a label-shaped rectangle.
