This paper provides guidance on the development of Safety Cases as a means of demonstrating the safety of a safety-related service or new/modified system. It is aimed at those, employed on projects or in service-provider organisations, which have to: Produce Safety Cases - eg safety practitioners; Approve Safety Cases - eg programme managers and senior line management within service-provision organisations; Review Safety Cases - eg safety department staff. The aim is to achieve sound, well-presented Safety Cases through the adoption of a logical, rigorous, consistent and accurate approach that is based on good safety practice. In a similar way to the presentation of a legal case, the importance of a clear, well formed and unambiguous argument, supported by appropriate, and conclusive evidence has been emphasised. Guidance on both aspects of a Safety Case is given in the paper. A Safety Case is commonly founded on showing that a system (or service) has been specified to be safe and that such specifications have been satisfied in implementation. It is stressed that both requirements specification and requirements satisfaction need to demonstrate that the system/service is safe when working normally (the success viewpoint) and remains safe when taking account of the reality that it will periodically fail in some way (the failure viewpoint). The paper is based on the experience of EUROCONTROL in the development of Safety Cases, and captured in its recently revised Safety Case Development Manual. Although the material is orientated towards the business of EUROCONTROL (i.e. Air Traffic Management) the author believes that is readily adaptable to other application sectors.
