Finding the Critical Path - A Simple Approach

Figuring out why a process in a batch window ended late often requires tracing back through the critical path to look for anomalies. In a complicated batch schedule, determining which jobs are on the critical path can be a seemingly daunting task. Various commercial products can be used for this task, but they may not be necessary. The code needed to determine which predecessor jobs constitute a particular job’s critical path is relatively, perhaps surprisingly, simple.
