Process Activities and Events 



  • Every diagram should have a start and end point.
  • A thin circle at the start of a process is called a start event.
  • A thick circle at the end of a process is called an end event.
  • Events do not involve work.


  • The rounded rectangles are called activities. They represent actions or work performed.
  • Activities are named in the form: VERB-NOUN, e.g. Check Credit, Review Plan, Complete Form. If an activity cannot be described in this way, it is not an activity.

Sequence Flow

  • The arrows, referred to as sequence flow, represent the logical flow.
  • This diagram below illustrates the normal path if nothing goes wrong.
