When applying the characteristic of a small organization, where 'one leader can oversee down to the front line', to a large-scale system, what concretely does 'n' mean in the constraint 'observable up to n levels'?

n is an appropriate natural number of 2 or greater, meaning the maximum number of nodes or the hierarchy level that a single supervisor can observe. Although n could be defined flexibly in different forms for individual nodes, if no definition is given at all, then in the review stage before application one may overlook the situation where a conclusion obtained in a small organization, where n can be ignored, fails to work in a large-scale system.
