Title Case study on risk analysis for critical systems with reliability block diagrams Type Conference Article
Year 2013 Publication ISCRAM 2013 Conference Proceedings – 10th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2013
Volume Issue Pages 693-702
Keywords Availability; Information systems; Reliability; Risk assessment; Risk perception; Complex failure; Critical systems; Failure category; Government; Organisational; Reliability block diagrams; Risk analysis methods; Vulnerability analysis; Risk analysis
Abstract This paper presents a practical risk analysis method for critical, large-scale IT systems in an organisation. The method is based on reliability block diagram modelling and was adapted to fit the requirements of governmental organisations and to reduce the effort required to capture complex failure behaviour. Through the use of different failure categories the risk analysis can be simplified, the input data becomes easier to estimate and the results are easier to use in an organisational risk and vulnerability analysis. The paper first explicitly describes the different steps of the method and then presents a case study in which the method was applied and evaluated in a real-life setting. The method is meant to help an organisation to communicate internally about the reliability of their critical IT systems and to prioritise proposed improvements to this reliability.

Title Risk analysis for critical systems with reliability block diagrams Type Conference Article
Year 2012 Publication ISCRAM 2012 Conference Proceedings – 9th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2012
Volume Issue Pages
Keywords Availability; Hospital data processing; Information systems; Reliability analysis; Risk assessment; Complex failure; Critical systems; Government; Patient data; Reliability block diagrams; Relief activities; Risk analysis methods; Vulnerability analysis; Risk analysis
Abstract Governmental organisations are becoming more critically dependant on IT systems such as communication systems or patient data systems, both for their everyday tasks and their role in crisis relief activities. Therefore it is important for the organisation to analyse the reliability of these systems as part of the organisation's risk and vulnerability analysis process. This paper presents a practical risk analysis method for critical, large-scale IT systems in an organisation. The method is based on reliability block diagram modelling and was adapted to fit the requirements of governmental organisations and to reduce the effort required to capture complex failure behaviour. The paper first explicitly lists the requirements that such a risk analysis method must fulfil, then presents the proposed risk analysis method and finally outlines the planned evaluation of this method. © 2012 ISCRAM.

Title Dependability of IT systems in municipal emergency management Type Conference Article
Year 2009 Publication ISCRAM 2009 – 6th International Conference on Information Systems for Crisis Response and Management: Boundary Spanning Initiatives and New Perspectives Abbreviated Journal ISCRAM 2009
Volume Issue Pages
Keywords Civil defense; Disasters; Information systems; Risk assessment; Risk management; Crisis situations; Dependability; Emergency management; Emergency planning; IT management; Municipal emergencies; Process improvement frameworks; Vulnerability analysis; Human resource management
Abstract In recent years governmental actors have become more and more dependent on IT systems for their responsibilities in a crisis situation. To avoid unexpected problems with the dependability of IT systems in the aftermath of a crisis it is important that such risks are identified and that measures can be taken to reduce the dependence on systems that could be unreliable. This paper describes two case studies exploring how Swedish municipalities incorporate IT systems in their emergency planning. The study focuses especially on how different actors within a municipality cooperate to analyse the risks of depending on IT systems in critical situations. The study shows that today there is much room for improvement, especially in the communication between IT personnel and emergency managers. Finally, this paper describes the requirements for a process improvement framework that can assist governmental actors in analysing and improving their dependency on IT systems in emergency management.
