How to Define and Document Use Cases

Course: USECS

Duration: 2 Days

Level: I

Course Summary

A business use case diagram is a visual tool that shows interaction between the environment and an evolving information technology solution. A single business use case is a textual tool for representing how individual end-users and other involved parties or systems (collectively referred to as "actors") will interact with the proposed system.

Knowing why you need a business use case, when it should be created, and where to put what information is critical to creating quality functional requirements. Without a common understanding of the purpose and structure of use case diagrams and the business use case document, use cases can quickly become "useless cases".

This training workshop offers use case training in the basics of use case documentation and business use case diagrams as tools for business systems analysts. It explains the who, what, when, where, why and how of business use cases and use case diagrams.
