Job Scheduling & Production Process Automation
This episode of the ISACA Certified Information Systems Auditor (CISA) exam prep series covers job scheduling and the automation of production processing. It introduces how organisations sequence and control batch workloads, manage competing priorities, and use scheduling software to keep operations reliable, with particular focus on what an IS auditor needs to examine when reviewing this function.
What this episode covers
- Job schedule structure — how the list of tasks, their sequence, and trigger conditions are defined and maintained.
- Job dependencies — why the output of one job must be available before the next can start, and how automation enforces this.
- Priority assignment — how high-priority jobs, maintenance tasks, and low-priority work are ranked and slotted across the available window.
- Scheduling software capabilities — automating the daily plan, dependency enforcement, logging, access control, and error reduction.
- Shrinking maintenance windows — the challenge of fitting heavy jobs into gaps when systems must be available around the clock.
- Auditor review checklist — what to examine in the schedule, console log, exception handling, rerun authorisation, and access rights.
Watch the full episode above for the worked examples and detailed explanations of each concept.
Frequently Asked Questions
What is a job schedule and why does the order of jobs matter?
A job schedule is a list of the processing tasks that must run, the order they run in, and the conditions that trigger each one. Order matters because one job often needs the output of another before it can start, so running steps out of sequence produces incorrect results. For example, posting transactions must complete before statements are generated, or those statements will simply be wrong.
How are job priorities assigned in a production schedule?
High-priority jobs receive the best access to computing resources, while maintenance work such as backups and data reorganisation is scheduled off-peak. Low-priority jobs are slotted in when processing time frees up. A well-built schedule also leaves room for urgent, unplanned requests so that they can be absorbed without disrupting everything else.
What does job scheduling software provide beyond manual scheduling?
Scheduling software automates the daily work plan, deciding which jobs to submit and when without requiring operators to intervene each time. It enforces dependencies so that a failed job cannot let the next one run on bad output, and it logs every success and failure. It also controls who can reach production data and reduces the manual effort and human error associated with running many batch routines.
What should an auditor check when reviewing job scheduling?
An auditor should verify that input deadlines, processing times, and output deadlines sit inside the agreed service levels, and that critical applications are identified and given top priority. The console log should be reviewed to confirm jobs finished as planned, failures were investigated and root causes found, and the right stakeholders were notified. The auditor should also confirm that any changes to schedules or priorities are made only by authorised individuals, and that reruns and exception jobs are approved, logged, and verified.
