Modularity can have a negative as well as a positive effect. A program that is over-modularized performs its operations in very small modules, so a reader has trouble acquiring a perspective. That is, although it may be easy to determine what many individual modules do and what small groups of modules do, it is not easy to understand what they do in their entirety as a system. Suggest an approach that can be used during program development to provide this perspective.

Top-?down development with careful attention to the intermediate level designs can help. Each component in an intermediate design is a description of a single task; this task can later be refined and implemented by many smaller modules. It isuseful to save the intermediate designs, because saving them ensures that they accurately reflect the final, detailed design, as well as the program produced. In this way, each intermediate design is a description of the collective functioning of a group of simple modules.
