What is Sequence Diagram?

A sequence diagram is a visual model describing how groups of objects collaborate in some behavior over time by capturing the behavior of a scenario of a use case. It shows objects and the messages that are passed between these objects for the particular collaboration.

How to draw Sequence Diagram

  1. Identify who starts the interactions (which actor)
  2. Describe the message exchange between actors and the business systems in textual form called flow of events
  3. Consider each of the flows in the flow of events repeatedly to identify the participating objects which are required to get the task done.
  4. Detail the message exchange between the participating object
  5. Consider the creation and deletion of object lifeline as well
  6. Review and touch up by running through the entire scenario
