\section{Introduction} E-government projects differ from others due to their complexity and extension \cite{anthopoulos2016egovernment}. They are complex because they combine construction, innovation, information \& communications technologies, politics, and social impact. Their extension, on the other hand, is related to their scope, target audience, organizational size, time, and the corresponding resistance to change. Government-academia collaborative projects can be considered an alternative to create novelty for e-government projects and to meet the needs of society. This collaborative work has challenges, such as organizing the collaboration project, aligning goals, synchronizing the pace of between government and academia \cite{anthopoulos2016egovernment}, and overcoming the failure trend of e-government projects \cite{goldfinch2007pessimism}. Poor project management is one of the main reasons why e-government projects fail \cite{anthopoulos2016egovernment}. When government and academia combine efforts to develop an e-government solution, the differences in the project management become an issue. Academia commonly work on cutting edge of technology while government is still relying on traditional techniques. Changing the development process in large-size institutions represents an organizational disturbance which impacts on structure, culture, and management practices \cite{nerur2015challenges}. As a result, government and academia have to harmonize their view to increasing the chances of success in projects with tight deadlines and short budgets. % TODO: Projetos de sl tem x características e muitas de suas práticas tem se mostrado válidas e que abrem precedentes para utilizar no contexto governo academia. Falar da influência do SL no projeto In this work we investigate a set of practices from a 30-month government-academia project that helped to harmonize the differences between government and academia management cultures. We trace the best practices based on open source ecosystems and agile methodologies. Finally, we validate their benefits by collecting data from the main project repository and by surveying the project participant points of view.
