Abordagens do PMBOK e CMMI sobre o Sucesso dos Projetos de Softwares

In recent decades, discussions, publications, methods and tools for project management are increased. At the same time, several studies are pointing the main causes for failures on projects, providing analysis on the causes and creation of best practices to help professionals to acquire maturity and repeat successes. Given the importance of the theme, this article describes the main approaches maturity model in software development by the Capability Maturity Model Integration (CMMI) and the best practices for managing project proposed by the Project Management Institute (PMI) by means of the Project Management Body of Knowledge (PMBOK), in order to compare them and raising requirements for effectiveness in management software projects. It was concluded that both the CMMI and the PMBOK has a focus on project management, but the structure is different from both and complete each other. The PMBOK provides additional processes for project management to CMMI, since it presents the planning documents, such as the communications plan, in more detail. Already CMMI provides a framework for managing and improving processes for best practices in software engineering, for data management and decision analysis.
