Discussion

A user is describing a real-life example during requirement gathering stage of a software development project.

This most appropriately represents which requirement discovery technique ?

  • A.Viewpoint
  • B.Interview
  • C.Scenario
  • D.Use-case

Answer: C

The technique is a scenario.

In requirements discovery, scenarios are real-life examples of how a system can be used: a description of a typical interaction, the starting situation, the normal flow of events, what can go wrong and the finishing state. Users find it easier to describe such a concrete example than to state abstract requirements.

An interview is the method of questioning stakeholders, not the content of what they describe. Viewpoints organise requirements by the different stakeholders' perspectives, and use cases are a more formal, structured way of identifying actors and their interactions, often built from scenarios.
