This unit shares lectures with CM30072.
Aims: To give an appreciation of the current state of safe systems development. To develop an understanding of risk in systems. To give a foundation in hazard analysis models and techniques. To show how safety principles may be built into all stages of the software development process.
Learning Outcomes:
A student will be able to:
* understand the concepts of safety, risk and the role of human factors in the design and operation of safety critical systems;
* understand the nature and role of the safety lifecycle in developing safety related systems;
* choose and apply appropriate hazard identification and analysis techniques for a variety of safety related problems;
* critically evaluate and reason effectively about hazardous situations in safety critical systems.
Content:
The nature of risk: computers and risk; how accidents happen; human error. System safety: historical approaches to system safety; basic concepts and terminology. Managing the development of safety-critical systems. Modelling human error and the accident process. Hazard analysis: basic principles; models and techniques. Safety principles in the software lifecycle: hazard analysis as part of requirements analysis; designing for safety; designingthe human-machine interface; verification of safety in computer systems.
