If the definition of coming from above is the package division manager, then I agree. It has been said that the operators are not allowed to make dispatch decisions. That I disagree with.
From my perspective (maybe not everyone else here), the package DM is is an operator. It is ultimately his responsibility to balance cost, service, etc.
I have seen many supervisors (even managers) who don't like the dispatch... I have not seen a package division manager who says he is putting out the wrong number of cars each day. I have not seen one who says that decision is not his / her's.

The have input of what route to cut, but not how many should be dispatched to acheive the plan.
They all have a target to reach. It's dictated from the top down. The corp, region, dist balanced scorecard sets the standard for what is acceptable. If you are not making the goal, it is the next levels obligation to take action. A center manager doesn't decide what his goal will be on a daily basis. In theory, the are supposed to have input, but it's just a theory. In the real world, the number they have to make in each element is dictated and tracked from above. In the case of routes, it's simple math. x number of packages = x number of routes to dispatch if the goal is going to be achieved. If you knowingly dispatch too many routes, failure to achieve the goal is certain.
I once heard a very well known upper level manager say "if you dispatch a driver with a 7 hour planned day, then the most you can get out of an 8 hour paid day is 7 hours worth of work. It's a plan to fail."
Seems like simple logic, but many seem not to understand the concept. You can apply this same simple logic to any element.
Would it make better sense to wait till the next day, and then say "darn, we didn't make the goal, looks like we dispatched too many routes?"
