Abstract: Finnish summary Diss.This thesis studies the life cycle of information systems (IS) from an organizational perspective.It states that the life cycle of an IS, as a sociotechnical system, is cyclical rather than linear.Within this cyclic view, the IS is renewed at certain intervals in order to stay aligned with organizational needs.An information system is a sum of social and technical elements.Misalignment between the elements creates pressure for change.When one of the elements changes the others adapt.The renewal of the technical element of an IS, i.e. the IT artefact, is labour-intensive and expensive.Consequently, the related decisions have to be well justified.Renewal triggers provide indication of the motive and criticality of the need for change.Benefit evaluation aims at ensuring that the renewal effort yields benefits and is worth the investment of organizational resources.Correct timing tackles with finding a time period during which the IT artefact renewal causes minimum hindrance for the organization's operation, and defining the suitable frequency of renewal projects.Together these three aspects determine the IT artefact renewal.
