I still believe in 20% time.
Not because it's trendy. Because sprint-to-sprint thinking creates tunnel vision.
Some leaders see it as wasteful. "We can't afford to have people not delivering features."
But here's what they're missing.
Turning a manual job into automation. Adding tests to an uncovered area. Trying a library that might simplify everything. These aren't extras. They're part of the process.
When you don't protect time for this, you end up living in a messy house. Every time you want something from the cupboard, you have to move four boxes, pull the door just right because otherwise it gets stuck, then put everything back or you can't see the floor.
You can live like that. People do. But eventually you stop opening that cupboard at all. You work around problems instead of solving them.
20% time is protected space to step back and view what you're building, and how, in a different light. Not just for developers. Product people. Designers. Anyone whose work compounds.
The dividends don't show up in this sprint. They show up in the team that's still sharp and engaged six months from now.
Take a moment. Spend some time. Ask how you could do something better.
