- Risk follow-up aims at analysis of operational events from their risk point of view usingprobabilistic safety assessment (PSA) as the basis. Risk follow-up provides additional insight tooperational experience feedback compared to deterministic event analysis. Even though thisapplication of PSA is internationally widely spread and tried out for more than a decade at manynuclear power plants, there are several problematic issues in the performance of a retrospective riskanalysis as well as in the interpretation of the results.An R&D project sponsored by the Nordic PSA group (NPSAG) has focused on selected issues in thistopic. The main development needs were seen in the handling of CCF and the reference levels forresult presentation. CCF events can be difficult to assess due to possibilities to interpret the eventdifferently. Therefore a sensitivity study with varying assumptions is recommended as a generalapproach. Reference levels for indicators are proposed based on the survey of criteria usedinternationally. The paper summarizes the results.

- The ICAO approach to risk management is essentially a technical model based on an engineering process viewpoint and is more applicable in concept to stable systems, such as chemical and nuclear industries. If airlines are to manage risk in a proactive manner they need to apply risk detection tools that provide real time and continuous systems oversight. This paper describes briefly the systems approach applied to the development and implementation of a dynamic Safety Management System (SMS) in a major airline in Europe with a focus on management of operational risks. This work has been realized as a part of the in the FP6 HILAS project. The SMS principally consists of a Risk Management System (RMS) and a Safety Assurance process. Principles of Organizational Learning and Resilient Safety Culture have been adhered to throughout this development. As a result, the RMS is conceived as an aspect system with functions, actors, supporting processes and connecting data streams. The work in progress demonstrates that integrating humans in processes of risk management leads to bridging expertise domains, enables improved business controls and efficiencies, as well as safety risks.
