【 摘 要 】

Moving from the results of a web survey we carried out in early 2006 we identified the main challenges in IT change management as planning and scheduling of changes; high number of emergency changes and ill- definition or wrong scoping of request for changes. In this paper we begin to address the problem of planning and scheduling changes taking business considerations into account, following a business-driven IT management (BDIM) methodology. We sketch a reference architecture which follows the principles of BDIM, comprising of a mathematical model linking IT availability metrics to business objectives (in our example: monetary loss due to availability service level violations). 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.
