Abstract

Data flow diagrams (DFD) and Use Cases are two popular methodologies in teaching as well as in practice.

Questionnaire results indicate that students perceive these methodologies as equally easy to understand and use. Students believe that data flow diagrams are better at communicating with users and programmers.
