I'm Head of Development in a midsized SaaS company. Another team's PM went for paternity leave and I stepped in to lean in on any needs.
I discovered that the team of 10 people were using close to an hour a day on stand-up. A culture thing, apparently.
I joined he stand-up a few times, slimmed the scope of the conversation to roughly 10-15 minutes.
This worked for all three months of the PM's paternity leave.
PM returns, is pissed over the change and in less than two days, the stand-up is back to almost an hour a day.
