What this search usually means in real life
This search usually comes from a team that has outgrown simplistic metrics. Hours are easy to count, but they are a weak proxy when work varies in complexity, interruptions are common, and output depends on handoffs.
The better question is what actually defines progress in your operation.
Teams celebrate busyness more than completed work
Hours rise during crunch periods without much output gain
Managers struggle to compare teams fairly
Blocked work stays invisible in reporting
Productivity conversations default to opinion instead of evidence
