Datorită Decidim, la Barcelona am reuşit să coelaborăm un plan de oraş strategic împreună cu cetăţenii. În 2016 am inaugurat Planul de acțiune municipal sub forma unui proces participativ prin Decidim Barcelona. În prezent, acest plan include aproape 7 000 de propuneri din partea cetățenilor. Unul dintre avantajele utilizării acestei platforme este că puteţi monitoriza în orice moment stadiul punerii în aplicare a propunerilor aprobate.

The process started in October 2019 at the European Commission’s DG Communication and eDemocracy unit at the Joint Research Centre, the European Commission's science and knowledge service. An analysis of the needs of the Conference and which tools fit those, lead to choosing the open source tool Decidim for its technical maturity, broad community and adaptability.
