You will find, as a systems analyst, that the person who designs a system is often not the one who develops the program for it. An acceptable design of a physical data flow results in:

a. A system that works

b. A system that fulfills user requirements.

c. A system that provides adequate performance.

d. A system that includes sufficient internal controls.

e. A system that is adaptable to everchanging requirements.

Find an example of a system DFD design that seemed acceptable, but did not result in a system that met the stated requirements.

Was the problem one of design or technical complications? Did the programmers understand what the analysts were requesting? Share with the class.
