<p>A computer system (900), method and computer program for controlling a workflow process. A process modelling unit (110) of the computer system is configured to define a process model (150) with at least a first task (151) and a second task (152), wherein the second task (152) needs to comply with a control aspect (200) and depends on the first task (151), and is further configured to insert into the process model (150) a control task (153) between the first and the second task, wherein the control task (153) is configured to enforce the control aspect (200) on the second task (152) by using a control service of a subsystem. A process execution unit (120) of the system is configured to generate a process instance (160) from the process model (150) and to instantiate a control context (180) to capture the current state (169) of the process instance (160), the control context (180) being used by an instance (163) of the control task (153) to invoke (450) the control service according to the control aspect (200).</p> |
