The document discusses the challenges and opportunities of adopting open source software (OSS) in European government procurement, highlighting that while there is political support for OSS, it is not yet widely implemented due to various barriers such as legacy contracts and perceived risks. Research indicates that OSS can offer significant benefits, including reduced costs and increased flexibility, but organizations often struggle with the transition due to misconceptions and a lack of understanding. Overall, fostering an ecosystem around OSS adoption could lead to enhanced collaboration, cost-sharing, and innovation among government entities.
