A method for effecting changes in a software system landscape with a plurality of logical software systems that are interconnected by logical transport paths, comprises: providing system role types, each system role being associated with one of a plurality of system role types; providing low level operational tasks associated to system role types; providing a transport track that defines a route through logical systems in a particular order and that specifies one source system, adjacent interconnected systems, and at least one target system; providing high level operational tasks in a software development system that define software changes; generating transport requests for transporting the software changes; and generating a low level operational task list for the logical systems affected by the changes to the software by: analyzing the transport track(s) and the system role types and selecting low level operational tasks associated with the system role types according to the high level operational tasks.
