Even though there has been a considerable amount of progress on software development tools, techniques, methodologies and SDLCs, still %68 of software development projects are unsuccessful. In this study, Flexible and Adaptive Life Cycle (FALC) Framework is introduced to manage the utilization of different SDLCs in the projects in order to increase success rates. The FALC Framework provides opportunities to combine different SDLCs and/or suitable parts of them at appropriate phases and use them

... jointly according to the project characteristics and needs. By combining various SDLCs, benefits of each can be reaped from them all. Moreover, the FALC framework can decrease development time and costs of the projects, provide a paradigm shift on using different SDLCs in parallel by different groups of the project.
