Everyone would prefer to live in a world where effective medium-range, medium-scope plans are possible.

Everyone has at least a slight preference for this; this means that even though it's a slight asymmetry, it's consistent, which means the effects of it will be massive.

All organizations ever pretend like medium-range planning definitely works if you just try hard enough and are smart enough.

However the direct evidence is that except when we get extremely lucky, medium-range, medium-scope plans almost never work as planned, in all but the most boring contexts.

Things happen, sure, but never according to plan, and often with significant swirl and coordination overhead that wouldn't have been necessary if a too-detailed, too-tightly-held plan didn't exist.

Every time the world doesn't fit your plan, you have to do a lot of swirl to fix it.

The world is fractally complex and constantly changing. Plans need to be fluid to have any hope of cohering!
