Analysis of ICT services by observing "fit for use" attributes

As organisations depend more and more on ICT services to meet their missions, ICT disruptions constitute an important risk to their resilience. Therefore, a systematic approach to prevent, predict and manage ICT services disruptions along their life cycle is needed. Simulation and visualisation techniques have been suggested as a means to explore “what-if” scenarios that allow organisations to prepare for different outcomes and consequently help them to improve their resilience. The research discussed in this paper explores how visual analysis of simula ted scenarios can be used as a decision support mechanism to evaluate ICT readiness for organisational resilience. In particular, it presents how this can be supported by our extension of xArchiMate, a tool for simulating and visualising enterprise architecture models. This approach is evaluated by conducting experiments using the tool, analysing the results, and discussing how other extensions can be made to model additional scenarios.
