Well, to be fair, that's what most people usually start out trying to do -- 
make it all line up neatly, with each department having numbers in a certain 
range  (1xx for management, 2xx for purchasing, 3xx for sales, 4xx for IT, 
5xx for shop floor, 8xx as short codes for direct access to selected external 
numbers from phones that shouldn't normally have access to outside lines but 
still need to call certain numbers occasionally)  and so forth.

But then, once you have invested considerable time and effort devising a plan 
for allocating numbers, somebody "On High" inevitably makes a decision that 
ruins the whole thing.
