Module Identifier sebern.2004.1
Abstract This module is designed to introduce the analysis and specification of software requirements using informal techniques. It is intended as preparation for the introduction of formal methods of requirements analysis, specification, and verification. It might also be used as a separate exercise. This module minimizes the complexity of requirements elicitation by using an example that will already be familiar to most students.
Size Lecture: 2 hours
Exercise: 2 hours
Comments This module is appropriate for inclusion in a first course in software requirements or in a course that applies formal methods to the documentation and analysis of software requirements. The example used in the module exercise can also be used as a vehicle for work with formal specification and modeling, as in a related module introducing formal specification (REQ2).
