1. Introduction Workflow management systems  support the definition and execution of business processes. Those business processes are made up of a set of activities. The sequence in which these activities are executed is specified via control connectors. Control connectors connect one activity, the source activity, with another activity, the target activity. It is important that the business processes as a whole as well as the individual activities are carried out in a certain time and that appropriate actions are taken if the specified times are exceeded. Thus the workflow management system must (1) provide the capability to specify those times and the actions that should be taken and (2) enforce these specifications when carrying out business processes. MQSeries Workflow  calls this function notification. This name has been choosen since notifying some person is the only action that the system supports if a specified time is exceeded. Figure 1 shows the notification that MQSeries Workflow allows to specify for a process. It defines that a notification is sent to the process administrator if the process has not been completed in 10 days.
