On successful completion of this module students should be able to:
1. Demonstrate increased awareness of issues of software quality and correctness and the consequences for development cost and timescale.
2. Have gained practical experience of working to the methodologies and standards used for the development of high integrity systems in industry.
3 Understand and be able to analyze the issues of working in a group where software integrity is paramount.
4. Demonstrate increased awareness of organisational and management skills.
5. Demonstrate the ability to provide a critical evaluation of their performance.
This module covers issues of system integrity and dependability and the consequences for development of safety-related computer systems. In addition to formal seminars based on directed reading, there is a group design project. This requires students to analyse a safety-critical scenario and then produce a design and safety case for a computer system of an appropriate level of integrity. In the project students will select suitable methods and techniques in accordance with international standards and established practice.
