1.Sequential model:

           - Those models are best suitable for small size projects,where all SDLC activities will be carried out one after another for the entire project.

           - These model consists of two models.They are

                                     1.Waterfall model

                                     2.V model

2.Incremental Model:

           - Those models are besst suitable for big-size projects.

           - This model consists of 5 models.They are

                                     1.RAD Model

                                     2.Fish Model

                                     3.Prototype Model

                                     4.Spiral Model

                                     5.Agile Model
