Which metric provides a comprehensive view of automation success by including exception and correction time?

Average Handling Time is the metric that provides a comprehensive view of automation success, particularly because it encompasses not just the standard processing time but also the time spent on handling exceptions and corrections. This gives a more holistic picture of operational efficiency in an automated environment.

When you're assessing the effectiveness of automation, it’s important to recognize any delays or additional time incurred due to exceptions. Average Handling Time reflects this by accounting for all activities involved in completing a task, including any time spent on resolving errors or performing corrective actions when automation encounters issues.

The other metrics have specific focuses. Straight-Through Processing Rate measures the percentage of tasks that go through the workflow without any human intervention, primarily looking at efficiency but not including exception handling. Successful Task Completion Rate evaluates the percentage of tasks completed successfully which doesn't account for time delays due to corrections. Document Accuracy Rate focuses solely on the correctness of processed documents and not on the time aspect. Thus, Average Handling Time stands out as the most comprehensive metric for understanding the overall effectiveness of automation.
