Companies fundamentally believe that their plan of record strategies will work.
Most strategies don't work.
They sound plausible, but turn out to not be viable in practice.
While deciding which plan to execute, you want more disconfirming evidence, in order to make a better decision.
But once a plan is the Official Plan, you move from wanting to find disconfirming evidence to wanting to find no disconfirming evidence.
Most disconfirming evidence comes from trying to do the thing and discovering that it's harder than you thought.
But any one person who finds that might be blamed by management.
So everyone tries really, really hard to make the plan work if it's possible, even if it's costly.
No one wants to be the person who raises their hand to say "I think this plan is impossible to execute" because whoever does that first might get shot.
So as a result a large organization shuffles forward like a zombie, attempting in vain to execute a thing that no one but the boss believes could actually work.
Organizations can often get stuck in this zombie shuffle!
