Apparatus and method for process monitoring

An apparatus for monitoring a plurality of process instances which have a common workflow, the apparatus comprising:

• a memory storing a model object reflecting the workflow, wherein the model object comprising a plurality of nodes with at least some of the nodes being capable of assuming at least active and blocked states;
• a processor arranged to receive events and change the states of the nodes in a corresponding model object instances in accordance with the events received to reflect the status of the process instances;
• the processor being arranged to repeatedly determine an “at risk” state indicator for the model instances, the “at risk” state indicator when set for a said model instance indicating that the corresponding workflow instance is in a state in which it cannot progress to a normal completion without encountering a node in the blocked state.

An apparatus for monitoring a plurality of process instances which have a common workflow, the apparatus comprising:

• a memory storing a model object reflecting the workflow, the model object comprising a directed graph comprising a plurality of nodes with at least some of the nodes being capable of assuming at least active and blocked states;
• a processor arranged to receive events and change the states of the nodes in a corresponding model object instances in accordance with the events received to reflect the status of the process instances;
• the processor being arranged to repeatedly determine an “at risk” state indicator for the model instances, the “at risk” state indicator when set for a model instance indicating that the corresponding workflow instance is a state in which it cannot progress to a normal completion without encountering a node in the blocked state, wherein the at risk state indicator is determined by defining a zone in the model based on a model topology and a location therein of a blocked node which is not active in a process instance.
