Figure 1 Â­ The design process with the three detailed stages of concept development. The initial concept development process is important because a better design process leads to. a better design outcome. Decisions made during the early stages of design tightly constrain. future options.
The development models are the various processes or methodologies that are being selected for the development of the project depending on the projectâs aims and goals. There are many development life cycle models that have been developed in order to achieve different required objectives. The models specify the various stages of the process and the order in which they are carried out. The selection of model has very high impact on the testing that is carried out. It will define the what, where and when of our planned testing, influence regression testing and largely determines which test techniques to use. There are various Software development models or methodologies. They are as follows:
