TAILIEUCHUNG - Lecture Software engineering - Chapter 6: Requirements modeling: Scenarios, information, and analysis classes

Chapter 6 - Requirements modeling: Scenarios, information, and analysis classes. At a technical level, software engineering begins with a series of modeling tasks that lead to a specification of requirements and a design representation for the software to be built. The requirements model1 - actually a set of models - is the first technical representation of a system. | Chapter 6 Requirements Modeling: Scenarios, Information, and Analysis Classes Slide Set to accompany Software Engineering: A Practitioner’s Approach, 7/e by Roger S.
