> My solution was to create a weekly "team meeting" from 8am to 11am every Friday and invite all of them to it.

I've been part of these and the focus time is nice.

It doesn't address the root problem, though. If engineers are being bombarded with meetings, those meetings just get squished into the afternoon time slot.

The secondary problem was that some people started treating the blocked-out time as their only work time. Once that dedicated block came to an end, they mentally switched out of work mode and were not going to do any more work until the next morning. Before all of the "nobody can do more than 3 hours of good work per day" replies, this was a real problem because people also used this time for discussion things with each other on the team, actual team meetings, and various things other than heads-down work, leaving less than the allotted time for actually working. It was also a problem when something would come up at 2:30PM and the person responsible would defer it to next morning's work session instead of taking an hour to do the work. This might all sound like minor annoyances and it was only some people doing it, but the theme repeated itself so much that many of us soured on the idea over time.

The bigger problem was that it didn't address the real issue. Every situation is different and in my case the manager was part of the problem. His solution to everything and answer to every question was to get two people talking. He thought of himself as a switchboard, routing people to other people on our team.

Blocking out meeting time helped a little, but what we really needed was an active manager who was handling communications himself and only bringing the team in when needed. We also needed him to have our backs when we declined meetings or asked if they could be an e-mail.

The healthier managers I've had take a constant, active interest in keeping their teams' meeting workloads down and rooting out interruptions and distractions. They also empower their team to forward meeting requests to the manager to evaluate and ask that external requests at least cc them for visibility. Every time I've had a manager like that, I haven't felt the need for blocked out focus time.
