REFERENCES 41 PROGRAM DEVELOPMENT PLANNING During the program development cycle a step-by-step process will be implemented to design an error-free program that produces the desired output. The following steps will be followed during work packages 2, 3 and 4 of the REDDES project: 1.Definition of the problem: During this step the program’s output is clearly defined. This means that it has been decided what the program should do and what the output should be. There is a clear idea of what data (or input) are given and the relation-ship between the input and the desired output. 2. Design: Planning of t
