Does a big improvement kill the habit of making small ones?

Put fresh paint on a wall and it still needs dusting the next week. Buy a brand new machine and it still needs a five-minute clean at the end of every shift. The big win doesn't remove the small work, it just adds a new layer that also needs looking after.

But I've seen teams act like the big project was the improvement effort. All the energy goes into the transformation, and the little daily fixes that used to happen — a jig that's slightly off, a form that's confusing, a five-minute walk that could be two — just stop. Like once the big thing is done, nobody feels the small stuff is worth the effort anymore.

Maybe a big change actually makes the small habit more necessary, not less. There's a whole new set of rough edges nobody's smoothed out yet, and no consultant coming back to point them out.

Curious if others have seen this. Does a big win kill the daily habit, feed it, or just have nothing to do with it?
