At its core, the Lean discipline of 5S is about having just what we need, at hand, uncluttered by that which I don't need. While easy to see in a physical setting, it is harder to detect organizationally.
But maybe this metaphor will make it a little easier. I read this uncredited "saying" earlier today:
If the horse is dead, dismount.
If the activity, meeting, program, newsletter, metric serves no purpose, adds nothing more than a dead horse would add, drop it.
Keep on learning.
