DSDM model focused on system development quickly to achieve the purpose of saving the maximum budget and time. Often this model or apply to small companies fund short time and less capital for the development of software systems. As shown above, the model DSDM as a closed circle and are focused on four key elements: Business requirements, function model, design and build, an implementation. Through each stage of development, the four elements repeating themselves, at each stage there are steps to identify the error review arise during software development. In addition, model Time and Cost DSDM often be hard to fix by Time and Cost resources are very limited, but the ever-changing Features over time, may be different today yesterday so traditional model longer appropriate than software projects funded and time limited. Hard Time and Cost to fix product quality will help make right with the process as well as the quality of the projects that are consistent with the initial capital spend. Time to fix it as DSDM, the model should have a job management tool to ensure that time up with the progress of the project, the model used here is called Moscow, through this model will target help identify critical functions and estimate the time of each function that under the priority. Since that would help us to easily manage the work of the project, the project helps to keep up with the tempo set.
