[D] Design criteria partitioning software modules to be followed is highly cohesive coupling
engagement, the appropriate size of block size, and the like appropriate dependencies module. Module plan
division should follow certain requirements in order to ensure reasonable module division and further ensure that
as a basis to develop a software system reliability, easy to understand and maintain.
Should be as low as possible coupling between modules, module cohesion should be as
high.
