Every place I’ve worked has had a “20% tech debt” time. Universally, it’s used as a reason to not fix technical debt as opposed to enabling engineers to fix long-standing problems. “Oh you need to re-write such and such? Well that’ll take 40% of your time for 3 weeks and the max time we can allocate is 20% so…”

Ensure you use the dysfunctional version of that, where some individuals are always outvoted.

Over time, they'll become some of your favorite object lessons about employee engagement!
