This chapter addresses the issues of modeling a real-world customer's need using requirement gathering techniques, fundamental doctrines, and tools.
The processes in a software engineering methodology transform a real-world customer's need into a computer system. The computer system is at best a model of the real-world customer's need. A close match between the computer system's behavior and the real-world customer's need's behavior enables the model to predict and simulate.
This thesis recognizes the importance of establishing the computer system model but can only give insights and not scientific guidance.
