Abstract: Systems and methods for tracking engagement with an online application while multi-task among assignments are disclosed. The technology tracks time an agent actively spends on each work item by tracking how long the tab is in-focus in the service console. Agents log in, and work may be routed to them, based on their capacity. After the agent accepts the work items, the system tracks the time the agent stays on each open work tab. Each time the agent switches to a different tab, or back and forth, the time count stops for the previous tab and starts counting for the current tab. When the agent closes the tab, the total active time spent on the related tab is saved along with the agent's work record. If an agent logs out, the active time is saved for all of their open work tabs and subtabs.
