Distinguishing Fact from Fiction in a System of Systems Safety Case number of senses. From an analytical perspective, we recognise that it would be a mistake to treat a SoS as ‘just another complex system’. The defining properties of a SoS mean that traditional analysis methods may fall short if applied without additional support. On the other hand, we also argue t

A Project Manager’s View of Safety-Critical Systemsion that is a requirement in increasingly more systems. As with any product development, the degree to which a safety-critical product is tested or proved should be based on ‘cost of failure’ that, in the final analysis, is a commercial decision based on benefits and business risk. It is argued that

System Safety in an IT Service Organization asset management, nationwide radiation monitoring and hospital medical records services. A recent internal audit examined the processes and documents used to manage system safety on these services and made a series of recommendations for improvement. This paper looks at the changes and the challeng

Integrating a Risk-based Approach and ISO 62304 into a Quality System for Medical Devicesheme, where documentation, verification and validation tasks to be carried out depend on the safety classification. This means that a risk-driven approach has become an accepted standard for medical devices..This paper describes how Systelab have progressively defined a quality system that integrate

Maintaining the Safety of Operational Health ICT Systemsdation Trust hospital has made to the challenge. From a set of ICT activities which were founded on informal but capable principles, the expansion of the computer systems identified the need for improvements. This increasing awareness was present in the wider NHS, resulting in the publication of sta

Testing of Safety-Critical Software Embedded in an Artificial Heartsues in such systems are similar to other safety-critical systems (e.g., nuclear power plants), domain-specific properties may warrant development of customized techniques to demonstrate fitness of the system on patients. In this paper, we report results of a preliminary analysis done on software co

A Risk Driven Approach to testing Medical Device Softwarevels of safety, it is essential to reliably reduce safety risks to a residual low level. This requirement is verified and validated mostly with software testing. An approach to software testing driven by safety risks is presented and complemented with comments from a real project where it has been a
