The Importance of Requirements Requirements define and measure the success of a system Even when a program does “what” it is supposed to do it still does not meet user expectations Getting the “real requirements” is hard Issues

Requirements Approaches Interviews Face-to-face Participatory Design Ethnography

Communication Issues Communication problems often the cause of inadequate requirements Terminology / jargon mismatch between end users and software developers Communicating via an artifact can help Face-to-face communication preferred but not always possible Issues

Transformations Many components in a user interface construction have fairly direct correlations to models used in requirements and design modeling.

Patterns Attributes deduced from textual argumentation and radio button options. Relationships deduced from references to lists. – Explicit Reference – Associated Actions Aggregation derived from lists and tables. Representations can vary, but in this case am using UML.
