Abstract

The role of independent safety assessment in managing project risks for new or modified programmable electronic systems for railways James Catmur & Mark Harrison Arthur D. Little, Science Park, Cambridge, UK, catmur.j@adlittle.com and harrison.mark@adlittle.com Abstract It is apparent that projects often run into late technical safety or safety regulatory related problems. With the increasing use of programmable electronic systems, and the increasing complexity of the applications which may result, these issues are becoming more prevalent. Many projects view the approval of newly developed or modified equipment as presenting one of the most significant risks to timescales and budget. In this paper we describe the role of an independent safety assessor (ISA) as described in current standards, and how the ISA role may be used as an effective tool for management of the impact of both technical safety and regulatory aspects of project risk. Use of the ISA in this rol
