Activity
SysML specifies several types of behaviors:
▪Activity
▪State Machine
▪Interaction
▪Opaque Behavior, which has subtype FunctionBehavior
An Activity is a major task that must take place in order to fulfill an operation contract.
An activity can represent:
▪An entire business process.
▪A step in a business process.
▪The invocation of an operation.
Activities can be decomposed into subactivities; the lowest-level Activity is considered a Task or Atomic Action.
Activities and flow of resources between Activities are modeled on Activity Diagrams.
