      1. Easy to use.
        1. Its usefulness is limited
          1. Software model
            1. Analyzes the needs of the end users of the software
              1. Decomposes and organizes the system, algorithms
                1. the source code is implemented
                  1. It is checked to see if it is working properly
              2. V-Shaped
                1. The V-model focuses on activities and correction.
                  1. The relationship between the development stages and the different types of tests facilitates the troubleshooting.
                    1. The tests can be expensive and sometimes not effective enough.
                      1. Software model
                        1. requirements gathering, accept test
                          1. Funtional specifications, integration test
                            1. HIgh level desing, system test
                              1. Low level desing, unit test
                          2. Incremental
                            1. Tasks grouped in small repetitive steps.

                                    1. Requirement, design, implementation and testing phases are completed for each iteration
                                2. Spiral
                                  1. The risk involved in software development is taken into account.
