An IS auditor found that operations personnel failed to run a script contributing to year-end financial statements. Which of the following is the BEST recommendation?

A closing checklist provides a systematic, documented process that operations personnel must follow, ensuring that critical tasks, like running year-end scripts for financial statements, are not overlooked. It acts as a control to verify completion of all required steps, reducing the risk of human error or forgetfulness.

Updating the operations manual might document the procedure, but it doesn't actively ensure the task is performed, as personnel might still overlook reading or following it.

Bringing staff with financial experience into operations doesn't directly address the procedural failure of running a script; it's a staffing solution, not a process control.

Retraining operations personnel might explain the importance of the script, but without a procedural control like a checklist, the risk of future omissions remains high.
