Question

What are the best practices to follow while writing a use case?

Answer 1

Some of the best practices to write a use case are as follows:

• To become a valid use case, the use case must provide some value back to the actor or stakeholder.
• The functional and non-functional requirements must be captured appropriately in the use case.
• The use case must have one or more alternate flow along with the main flow.
• The use case should only describe what the system does and not how it is done which means it will not describe the design. It will act as a black box from the viewpoint of an actor.
• The use case should not have any, i.e. it should be stand alone.
