All modules are not created equal

Description:

The defining characteristic of modules is that they are independent of one another, constrained only by their adherence to a common set of design rules. In the early stages of a modularization, this degree of independence may be more of an ideal than an accomplished fact. Nevertheless the lingering conflicts do tend to be worked out so that eventually, "true" modular independence is achieved.
