Each process model follows a particular life cycle in order to ensure success in process of software development. Software life cycle models describe phases of the software cycle and the order in which those phases are executed. Each phase produces deliverables required by the next phase in the life cycle. Requirements are translated into design. Code is produced according to the design which is called development phase. After coding and development the testing verifies the deliverable of the implementation phase against requirements. There are following six phases in every Software development life cycle model: 1  Requirement gathering and analysis. 2  Design.
If the developed code has a lot of bugs and issues then the maintenance phase will be the most expensive phase and there is a potential that the business can also get effected,causing further expense to the client.evelopment-The actual development of the product, at first look it appears to be the most expensive part of the software development Testing-Testing the product to specification, and if it confirms to the requirement Operation and Maintenance-This consist of about 60% - 70% of the SDLC.
