This study it will contribute for the dissemination of the knowledge related to the control of the inevitable changes that occur during the process of software development, causing alterations the budget and cronograma of the projects, with the use of the MRR. Beyond the basic concepts, some of the existing tools will be presented that automatize the creation of the matrices. Figure 1 below shows the result of a research carried through in 2009 for the Standish Group, called Soils Summary 2009 10 Laws of Soils, which show the results of projects that had had total success, partial or that they had failed. One understands for partial success projects that even so are functioning, had been you deliver without taking care of to the considered cost or the cronograma, or had had the target partially delivers, with little resources functions of what they had been required. It is pointed that the main causes of the problems are on to the requirements (THE STANDISH GROUP, 2009): 16 Figure 1: Projects that had had total success, partial and that they had failed Source: The Standish Group, 2009 Gives credit that the due given attention to the GR. and the correct application of the methods and tools of the MRR will make with that the companies obtain to diminish this number. Of this form, this work will substantially contribute so that the enterprise community has access to the excellent information for the production of software with quality, in what it refers to the rastreabilidade of requirements and the use of matrices, also adding knowledge to the academic community, supplying lines of direction disciplines to them related to the subject in question.
