After the computer programs have been prepared, the developed software along with the associated hardware enters the implementation and operation phase. The goal of this chapter is to describe the main activities of the implementation and operation phase, which include testing and debugging of programs, complete documentation of the system, changeover to the new system, and system modification and maintenance. TESTING AND DEBUGGING Definition of Testing and Debugging So long as computers are programmed by human beings, computer programs will be subject to errors. Program errors are known as bug...
