NON REGRETTABLE > 5% I don’t care how “cracked” your team is. If your team is bigger than 50 people and your annual non regrettable attrition is less than 5%, you’re not doing a good job of increasing talent density. This applies to every sub-team that’s > 50 people (including engineering). For context, a very large and spectacularly performing public tech company has 10%+ non regrettable attrition in their engineering team, which is widely regarded as one of the best teams on the planet. TLDR you need to raise the bar every year by weeding out the bottom 5%+. Period.
