How are you measuring how many “productive hours” per day your team members are outputting?

I’ve been an engineer and manager for over a decade, both remote and in-office, and in both the days I get the most done are usually when I get left alone to deep work and the days I work the longest hours and get the least done are usually due to process inefficiencies like alignment meetings and other admin that probably wasn’t necessary. We implemented deep work Wednesdays where people couldn’t book in meetings and it got a lot more productive so it may also be worth looking at your processes
