1. A workflow management system with continuous status management in a hospital or a hospital department, comprising: a first apparatus adapted to detect fuzzy process definitions of a clinical workflow; a second apparatus adapted to iteratively generate instruction volumes for controlling activity stages according to said fuzzy process definitions in said clinical workflow for the purpose of processing the process definitions; and means for evaluating the process definitions for each clinical process instance, the means for evaluating including a functional stage for initiating the activity associated with the activity stages and reporting the state of the activity to the second apparatus; wherein the second apparatus iteratively generates the instruction volumes based on the reported state of the activity so that the instruction volumes are continuously matched to circumstances and respective statuses or process progress of the activity.
