Program development involves finding a solution to a problem and then writing the problem solution in a programming language to produce a computer program. The program development process is a well-defined sequence of activities carried out by the programmer. The outcome of this process is a correct and good-quality program.
The software development process can be considered as part of the software life cycle. Two important and widely known models for the software life cycle are the waterfall and the spiral models.
The software development process is a well-defined sequence of tasks that are carried out to produce a program that is a computer solution to the given problem. It is strongly recommended to follow a software development process even for small programs.
