8.1 Introduction No program or system design is perfect. Communication between the user and the designer is not always complete or clear and time is usually short. The result is errors. The number and nature of errors in anew design depend on several factors.
1. Communication between the user and the designer.
2. The programmer’s ability to generate a code that reflects exactly the system specifications. These factors put an increasing burden on systems analysts to ensure the success of the system developed. The quality of a system depends on its design, development, testing and implementation.
