The purpose of this study is to carry out a systematic literature review with meta-analysis, seeking to understand, from the perspective of public governance, how the Digital Era of Governance is impacting governments, which social contracts should be considered in a digital governance model, and which are the main barriers of digital government to the public policies design. The research uses the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol to record the evidence found. The contribution of this study to the observation of Digital Era Governance for government strategies points out that the most evident component of reintegration in governments are government portals that promote detachment from the central government and reduction of the burden on the State, the most apparent holism component are the digital services of social benefits, and the most evident digitization component were government portals with full availability of State services and improved search. Evidence is shown that government as a platform is the social contract model most available to society. It is also pointed out that the lack of knowledge and experience in technology was the most significant barrier to designing public policies focused on digital government.
