Focus Depth

In-Depth Definition

Focus depth is often more useful than raw activity because many valuable tasks require sustained attention. It can reveal whether meetings, tool interruptions, or context switching are fragmenting output. Managers should use focus-depth trends to improve systems, not to punish isolated days.

How It Works in Practice

• Sustained periods in a single work context are measured, rather than the total volume of input.
• Interruptions are counted by how badly they break a session, since a two-minute interruption can cost far more than two minutes.
• Trends are read across weeks, because any individual day is dominated by whatever happened to be scheduled.
• It is a diagnostic on the working environment rather than an assessment of the person.

A Worked Example

A team's focus depth drops from an average of 70 uninterrupted minutes to 25 across a quarter. Nothing about the people changed. A new daily standup was moved to 11am, splitting every morning in half. The metric found a calendar problem, which is exactly the kind of problem it is good for.

The Common Mistake

Using it to rank individuals. Focus depth is largely determined by role and by the meeting culture around a person, not by their discipline. A support engineer will never show the focus depth of a backend developer, and comparing them tells you nothing except which job involves more interruptions.
