Situational Factors in Safety Critical Software Development
نویسندگان
چکیده
The generic software development situational factors model has been developed in order that environments within which software is developed can be profiled and better understood. Situational context is a complex concern for software developers, with a broad set of situational factors holding the potential to affect any one software development project. Safety critical software development is broadly similar to other kinds of software development / engineering. But there are some additional or more dominant situational factors. In this article we conduct a conceptual experiment to define safety critical software development context using situational factors. Eleven such factors are identified, with some of the factors requiring elaboration beyond the detail presently available in the generic situational factors model. We firstly discuss the appropriateness of the selected factors in generic safety critical software development context. Thereafter we apply the selected factors to the medical device and nuclear power domains. Selected situational factors can be used as a high level profile and starting point for more detailed process and safety assessment. Discussion about potential use cases and further development needs is also presented.

The situational factors that affect the software development process: Towards a comprehensive reference framework
Context An optimal software development process is regarded as being dependent on the situational characteristics of individual software development settings. Such characteristics include the nature of the application(s) under development, team size, requirements volatility and personnel experience. However, no comprehensive reference framework of the situational factors affecting the software ...
متن کاملChanging Situational Contexts Present a Constant Challenge to Software Developers
A software process can take many forms and its optimality demands that it should be harmonised with the needs of the given software development situational context. This theoretical proposition is reasonably clear. However, the finer details of the interaction between the software process and the factors of the situational context are much less obvious. In previously published research, the aut...
