It doesn’t necessarily change the scope, but it definitely changes the scale.
Just one example. In a country of 3 million people you can probably get away with having one office that handles visa applications and passport applications.
In a country 100x larger, you’d need to hire so many employees for both that each sub department will grow so large that they are effectively independent from each other and have separate physical infrastructure, separate digital infrastructure etc…
Then once you have all these separate sub departments you have sub departments that pop up just to service other sub departments.
It’s just an extension of graph theory. The number of connections between nodes grows non linearly with the number of nodes.
Take any organization. The percentage of support staff vs direct revenue generators increases with the size of the company.
The number of support staff vs front line fighters grows non linearly with the size of the army.
