 We worked on a three-year-long Brazilian government project to evolve an
-existing platform that had technical issues and lacked political support.
-This project, started in 2014, was a partnership between the Ministry of
-Planning, Budget, and Management (MP) and two public universities:
-University of Brasília (UnB) and University of São Paulo (USP), to
-modernize Brazilian Public Software (SPB) portal.

-With this partnership, the SPB Portal (www.softwarepublico.gov.br) evolved to a

-Beyond these technical and organizational issues, we had to overcome strong political bias and relatively low budget. The project suffered significant interference from the board of directors because the SPB Portal represents an interface between government and society. In light of political interests, directors continually imposed changes to the platform while ignoring our technical advice. During 2015, Brazil faced a political crisis that impacted the SPB: the board of directors was changed twice and, with it, the vision of the project. New directors primarily focused on keeping their distance from previous administrations.
