Thus the development process can be considered as a sequential flow in the waterfall. A generic, repeatable process for debugging software. The bestknown lifecycle model is the waterfall model consisting of a requirements definition phase, a design phase, a coding phase, a testing phase, and a maintenance phase. During the implementation portion, the developer creates the actual product, and the product is installed and ready for coding. Things need to be done about code that are not just typing compiler input. The software engineering model tends to view generalised functionality as paramount and central to the process. In the process of coding, the lines of code keep multiplying, thus, size of the software increases. Once the design is complete, most of the major decisions about the system have been made.
