Accepted Answer

A) True 
 B)False  False

Question 3

Summarize the quality checks that should be performed when reviewing structure charts.

Accepted Answer

Design the system so that there is a high fan-in structure.Create library modules whenever possible.Limit the span of control of the control modules to no more than seven subordinates.Make sure that each module performs only one function.The modules should sparingly share information,and make sure that the data couples that are passed are actually used by the accepting module.Control couples should be passed from low to high,not the other way around.Also,the module should have a reasonable amount of code associated with it.
