Zusammenfassung:A method of changing an information technology system comprising a plurality of interacting components is provided. In an embodiment, the method comprises defining (320) a plurality of maintenance windows; providing (330) a database (110) of required component changes, each change comprising a workflow of at least one activity having a predefined duration, each change being labeled with a set of attributes including a list of acceptable maintenance windows; providing (340) a database listing said components and dependencies between said components; generating (350) change constraints for required component changes based on said dependencies and the required component changes; generating (360) a set of individual preference scores for the generated change constraints; and scheduling (370) changes in available maintenance windows using the individual preference scores. In addition, a computer program product is provided that, when executed on a computer, is adapted to execute at least some of the steps of an embodiment of the method of the present invention to provide a change schedule for an IT system.
