Abstract |
Crisis organisations depend on telecommunication services; unavailability of these services reduces the effectiveness of crisis response. Crisis organisations should therefore be aware of availability risks, and need a suitable risk assessment method. Such a method needs to be aware of the exceptional circumstances in which crisis organisations operate, and of the commercial structure of modern telecom services. We found that existing risk assessment methods are unsuitable for this problem domain. Hence, crisis organisations do not perform any risk assessment, trust their supplier, or rely on service level agreements, which are not meaningful during crisis situations. We have therefore developed a new risk assessment method, which we call RASTER. We have tested RASTER using a case study at the crisis organisation of a government agency, and improved the method based on the analysis of case results. Our initial validation suggests that the method can yield practical results. © 2012 ISCRAM. |

Abstract |
Protection of society against natural and man-made disasters is high on the societal and political agenda. Effective crisis management is more important than ever. Nowadays, crisis organisations depend crucially on reliable telecom services, and unexpected failure of telecommunication may have serious consequences. In order not to be caught unprepared, crisis organisations should therefore perform a risk assessment on telecom availability. Unfortunately, assessment of availability risks of modern, multi-operator telecom services is difficult; information sources are unreliable, and the relevant information is uncertain and difficult to obtain. This paper describes some of these difficulties, as well as the requirements of availability risk assessment methods for crisis telecommunication services. The paper outlines a new method that can be applied without requiring full knowledge of the physical layout of the telecom infrastructure. This new method relies on telecom service diagrams as a tool for risk analysis and to facilitate dialogue among the analysts. |

Abstract |
Telecommunication services are essential to modern information systems, especially so for crisis management. Telecoms systems are complex and difficult to analyse. Current risk assessment methods are either not used because of their complexity, or lack rigorous argumentation to justify their results because they are oversimplified. Our challenge has been to develop a risk assessment method that is both usable in practice and delivers understandable arguments to explain and justify its risk evaluations. After experiments to validate the method in laboratory environments, we now present the first results from successful application with practitioners in a regional crisis organization that provides evidence about the practical usability of the method. |
