An activity is the smallest unit of a business process which involves an operation. A logical set of activities that are connected and performed in a sequential manner having a start and end point and focus on achieving a common goal form a business process model. While designing a business process model an activity is represented as a BPMN construct, and is a generic term for work that is performed within a business process. An activity is said to be atomic when there is only a single activity to be performed whereas an activity is said to be non-atomic when there are several other activities that it is dependent upon and vice-versa. The different types of activities that are a part of a process model are simple activities, User Interface, Web services, decision tables, transaction, sub-process activity, and case activity. In Process Platform, an activity is represented using the following graphic:
