From the results of a web survey we carried out in 2006, the main challenge in IT change management from a change manager's perspective was identified as planning and scheduling of changes. This paper begins to address this problem by taking business considerations into account; this is done through a business-driven IT management (BDIM) approach. A reference architecture that follows BDIM principles is sketched; it includes a mathematical model linking IT availability metrics to business objectives. Monetary loss due to service level violations on service availability is used as the main business metric. We present a numerical illustration of how the derived metrics may support change management decisions in order to plan and schedule changes to minimize adverse business impact. Keywords: Change management, business-driven IT management, service level management, Information Technology Infrastructure Library (ITIL), business metrics, modeling, performance evaluation, business impact, decision and negotiation support tools.
