Pre-executing workflow preparation activities based on activity probabilities and system load and capacity threshold requirements

A computer program product for operating a workflow system wherein the workflow comprises a given sequence of activities, the computer program product comprising a computer usable medium having computer usable program code tangibly embedded therein, the computer usable medium comprising:

• computer usable program code configured to automatically identify a pair of a primary activity and an associated preparation activity required to be done before executing the primary activity;
• computer usable program code configured to navigate through a process template of the underlying workflow, and to calculate a probability at a subset of nodes of the process template that said primary activity will be reached for a current process instance;
• computer usable program code configured to pre-execute said preparation activity in parallel to said given sequence of activities when said probability exceeds a predetermined threshold, wherein the predetermined threshold is determined by current system load and the workflow system's capacity, and wherein the process template of underlying workflow is unaltered;
• and
• computer usable program code to perform a next scheduled process step of the process template of underlying workflow when the probability does not exceed the predetermined threshold, and wherein determining the predetermined threshold includes utilizing measured workflow system and system load performance data obtained during runtime to dynamically update the calculating of the probability and dynamically set the predetermined threshold.

An apparatus comprising:

• means for automatically identifying a pair of a primary activity and an associated preparation activity required to be done before executing the primary activity;
• means for navigating through a process template of underlying workflow, and calculating a probability at a subset of nodes of the process template that said primary activity will be reached for a current process instance;
• means for pre-executing said preparation activity in parallel to said given sequence of activities when said probability exceeds a predetermined threshold stored in a computer storage device, wherein the predetermined threshold is determined by current system load and the workflow system's capacity, and wherein the process template of underlying workflow is unaltered;
• and
• means for performing a next scheduled process step of the process template of underlying workflow when the probability does not exceed the predetermined threshold, and wherein determining the predetermined threshold includes utilizing measured workflow system and system load performance data obtained during runtime to dynamically update the calculating of the probability and dynamically set the predetermined threshold.
