Aims

This module describes the role of requirements in the construction and continued maintenance of large, complex and evolving software-intensive systems. It introduces the important concepts and activities in systems requirements engineering, explains how they can knit together to form a through-life requirements engineering process, and demonstrates how such an end-to-end process can be defined and used in practice. The module provides a broad overview of the notations, techniques, methods and tools that can be used to support the various requirements engineering activities, and complements this with the opportunity to gain experience in a selection of these. The module seeks to illustrate the wider applicability of requirements engineering to everyday projects, the breath of skills required and the many contributing disciplines.

Learning Outcomes

On completion of this module, the successful student should have a good knowledge and understanding of the role of requirements engineering in the development of software-intensive systems and of the various activities involved in requirements engineering. The successful student should also be able to elicit, model, analyse, communicate, and evolve system requirements using state-of-the-art requirements modelling techniques and tools.
