Tracking worker performance using profiles, subtotals, and the Activity Log
Introduction
Using subtotals on the Activity Log from a worker's profile gives you a broad overview of their contributions during a given date range. By clicking on a particular activity you can review a summary of all the related activity. For example, if you click the "Comment Created" activity, you'll be shown a list of all the comments created by that worker. This provides insight into how workers spent their time in the helpdesk.
