Communication is a measurement of the practical toughness of a module. A component with high cohesion and reduced coupling is functionally independent of other modules. Here, functional freedom implies that a natural component performs a single procedure or function. The coupling means the overall organization in between the modules. Coupling relies upon the information supplied via the user interface with the complexity of the user interface between the components in which the recommendation to the section or module was created.

The level of combining in between two modules depends on the intricacy of the interface. The nimble SDLC design is a mix of iterative and incremental process designs with a focus on process flexibility and customer satisfaction by quick shipment of functioning software program products.
