Silver Software Consultants Limited has a proven track record of developing real-time embedded software for safety-critical applications. Working in all areas of the lifecycle, Silver Software has solid experience of the Safety Engineering processes, tools and techniques used to manage, develop, analyze and evaluate high-integrity systems across a wide spectrum of safety critical industries Silver Software is accomplished at systematically analyzing systems in order to evaluate and reduce risks. Of course, we appreciate that every project is different; however, very generally, the techniques we use during a safety lifecycle can be grouped within the following overlapping phases: Preliminary Hazard Analysis - During the initial stages of the development lifecycle, the hazards are identified and analyzed. The associated risks are classified and measures drawn up to either eliminate or reduce to a tolerable level, those risks that are unacceptable. Proven predictive and target-setting techniques are used, including ALARP. System Hazard Analysis - During the design & decomposition and implementation stages, the system is analyzed to determine failure causes. The results are used to guide further safety analysis and inform the design. Safety related risks are managed, tracked, and revisited when changes occur. The system is also assessed against requirements and relevant standards. System Safety Assessment - Whilst integrating and testing the system, the identified hazards are reassessed to ensure that each has been sufficiently addressed. Further analysis confirms the extent to which the design meets the requirements. Safety Case Compilation - A safety argument shows how the evidence is combined to provide an assurance of safety. Silver Software has experience in the use of graphical notations such as Goal Structuring Notation for expressing the structure of an argument. Silver Software is able to offer the following safety engineering services: Safety Engineering - Silver Software can carry out all aspects of the safety life-cycle, ranging from delivering individual elements of the processes outlined above to entire project safety management. Safety Consultancy - Based on our experience, we can advise on aspects ranging from the most appropriate choice of hazard identification techniques, where to focus safety process resource and when risks have been reduced to acceptable levels, to safety management system and safety programme plan content. Independent Safety Audit / Assessment / Advice - We are able to offer confidence in a product by independently demonstrating conformance with standards, plans and procedures. Our systematic approach allows early risk appreciation - delivering significant cost benefit. We invariably achieve precise results on time, to budget and with complete client satisfaction. Standards and Guidelines Used Include: Defence Standard 00-56 IEC 61508 DO-178B the rail industry's Yellow Book CENELEC EN 50126, EN 50128 and EN 50129
