Introduction
It is now widely recognised that the primary sources of latent systematic errors in safety systems lie in the requirements capture activities. It is also becoming recognised that dynamic State-Transition based design methods are more effective at capturing functional requirements than static documentary methods. Complex systems in the defence, aviation and nuclear sectors are often defined using State-Transition charts, and the value of this methodology is becoming recognised in the process sector.
Commercially available Off The Shelf (COTS) safety technology assessed against IEC-61508 is primarily intended for the process industries. However, there are now financial pressures to apply this technology in applications that have traditionally used bespoke solutions. For example, the UK defence sector applies Def-Stan 00-56, which places much greater emphasis on the inclusion of all aspects of the technology (hardware, software and lifecycle) with a much repeated requirement for evidence based substantiation.
