The Real Cost of Context Switching After a Meeting Interruption

A meeting's cost isn't just its length. It's also the time spent winding down before it and getting back into focused work afterward. For complex work, that recovery time can be bigger than the meeting itself.

What research shows

Gloria Mark, a researcher at the University of California, Irvine, who studies attention at work, found that after an interruption it took people about 23 minutes on average to get back to their original task. People often handled other tasks in between before returning. The exact number varies by person and task, but the pattern is consistent: interruptions cost more than the interruption.

Why meetings in the middle are expensive

• The approach: in the half hour before a meeting, many people avoid starting anything deep because they'll be cut off.
• The switch back: reloading a complex problem, like code, analysis, or writing, takes real time.
• Fragmented days: a meeting at 10, 1, and 3 leaves no two-hour block for deep work, even if the meetings only total two hours.

How to reduce the cost

1. Cluster meetings together, in the morning or after lunch, and keep the rest of the day open.
2. Protect focus blocks of two hours or more in the calendar.
3. Replace status meetings with written updates.
4. Leave yourself a note before a meeting: one line on what you were doing and what's next. Restarting from a note is much faster.
5. Make meetings shorter and end them on time.

Put a number on it

Most teams underestimate meeting costs because they only count the scheduled minutes. The Meeting Cost Calculator shows the live cost of a meeting from attendees' salaries; add the recovery time and it becomes much easier to decide which meetings deserve a slot.
