How does improvement happen?

First by collecting feedback, both quantitative and qualitative.

Then by looking at what that feedback might be telling you about what’s happened in the past, and what is likely to happen in the future if nothing changes.

Then by adjusting the system accordingly.

Your adjustments might be wrong of course, which is why it’s a good idea to keep them small until feedback shows you’re heading in the right direction.

Over time you’ll learn to keep it simple.

Then improvement will come naturally.
