Safety Case Practice - Meet the Challenge

Abstract

FREQUENTIS is a producer of voice and data communication systems in many different areas like air traffic control (ATC), public transport, maritime and public safety. Our customers are spread around the world. Most of our products are used for safety related or critical tasks. Therefore our customers often demand or need a safety case, partly to be allowed by the authorities to “go live” with their system.

This is a particular challenge for our safety work, as different standards in varying depth of compliance are to be fulfilled. Due to limited budgets caused by a rather hard competition on the market, it is necessary to perform the work as effective as possible.

In this paper we want to show, how we perform safety programmes for our voice communication systems, how we try to reduce our efforts with maximum output in spite of the difficulties of different business areas with different standards (which occasionally change quite substantially over time). This includes the presentation of our safety management system, hazard log, internal trainings, safety analyses and the production of safety cases.
