1. A method for designing one or more computer-aided tasks for at least one medical task flow executable by a central strategy manager (CSM) in a system including a front end device and a back end device, the method comprising: providing the one or more of the computer-aided tasks of the at least one medical task flow, configured to exchange data with other tasks, in so far as the other tasks comply with at least one port requirement, specified in a port contract negotiated between the tasks and the CSM, for exchanging data with the other tasks over ports specified in the port contract; providing task flow management, to manage task requirements, specified in a task contract negotiated between the tasks and the CSM, in respect of a task and to grant a task access for the medical task flow, if the task utilizes interfaces that comply with protocols specified by the task requirements; providing at least one task container, made available as host for a task, in so far as the task complies with at least one container requirement, specified in a container contract negotiated between the tasks and the CSM, for access to the host using services specified in the container contract; and providing at least one domain platform, to convert functionality and logic of at least one task such that the at least one task complies with at least one medical standard being implemented by the at least one medical task flow, in so far as the at least one task complies with at least one domain requirement, specified in a domain contract negotiated between the tasks and the CSM, in respect of the conversion, the functionality and logic being at least one of medical imaging, data transfer, and data management, wherein the functionality and process logic of the at least one task are implemented in the back end device and presentation logic of the at least one task is implemented in the front end device.
