What is a 'use case' in business analysis and how is it used?

Show answer & explanation

Correct answer: A description of how an actor (user or system) interacts with the system to achieve a specific goal, used to capture functional requirements

Explanation

A use case describes a system's behavior from the user's perspective — a sequence of steps showing how an actor achieves a goal. Use cases are a classic BA tool for capturing and communicating functional requirements.

**Why not B:** A business case document used to justify a project is a separate artifact from a use case. Business cases evaluate project viability and ROI, while use cases describe specific user-system interactions. The similar terminology can be confusing, but they serve entirely different purposes in BA work.

**Why not C:** A legal precedent for resolving requirements disputes does not describe a use case. Use cases are modeling tools that capture functional requirements by describing how actors interact with a system to achieve goals, not legal frameworks for dispute resolution.

**Why not D:** A case study of a similar project used as a planning reference describes benchmarking or lessons learned, not a use case. Use cases focus on defining the specific interactions between users and the system being developed, not on reviewing past project experiences.
