Use Cases


User Object Model

Use Casesdefine the use, from the end-users' perspective, for accomplishing a specific goal within a system.

A single use case describes a set of steps — a sequence of user interactions — to successfully accomplish the goal. The ‘use case brief’ outlines in a few sentences what the use case is about. The collection of all use cases defines the functional scope (everything that can be done with the system by all users). A use case describes the ‘what’ and not the ‘how’.

Summary

UCD leverages efficiency within research and developmentVisual Modeling facilitates communication and a comprehensive understanding of the system regarding

business processes and task flows / use casesobject structures and information architecture

A comprehensive understanding of the system from an end-user’s perspectiveprovides a solid basis for deriving product strategy enables a modular, scalable architecture via focusing on the big pictureavoids patchwork solutions that limit the flexibility and address isolated parts of the user‘s tasks
