To introduce students to the complexity of software systems engineering and the use of models and appropriate management processes in the understanding and control of the professional analysis and development of such systems in the face of change.
On completion of the unit the students will be able to:
1. Explain the relationship between science and engineering;
2. Describe a range of approaches to Systems Engineering, their advantages and disadvantages, and select between them;
3. Investigate and capture a software systems engineering problem;
4. Apply appropriate techniques for the creation of models at many levels;
5. Progressively refine problem definitions from high to low level;
6. Explain the issues and practical implications of verification and validation, and be able to devise a test plan from a specification;
7. Design, conduct and analyse experiments and transfer these skills for the analysis of the behaviour of software systems;
8. Understand the constraints on project development - resources, legal, ethical and professional.
