Who’s behind the platform?
Metadecidim is the community that collaborates in the design of the platform and the development of the project. Together we design and create new features and report bugs for continuous improvement of the platform.
The Decidim Free Software Association is a democratic association for the governance of the Decidim community.
Part of what makes Decidim so powerful is that it adds a level of abstraction to the work separating out the steps of a process and the activities associated with the process. That’s part of the information architecture, so that not only you are saying what is happening at each step but different parts of Decidim behave differently depending on when you are doing or depending on what step in the process you are in. The fact that that’s customizable really allows Decidim to be moulded to how we are doing our work and not our work to be moulded.

Grâce à Decidim, nous sommes parvenus à coproduire un plan stratégique pour la ville de Barcelone avec ses citoyens. En 2016, nous avons inauguré le Plan d’Action Municipale sous la forme d’un processus participatif par le biais de Decidim Barcelone. Actuellement, ce plan comprend près de 7 000 propositions citoyennes. L'un des avantages de l'utilisation de cette plateforme est que vous pouvez contrôler à tout moment l'état de mise en œuvre des propositions approuvées.

Nous manquons d'espaces publics pour nous exprimer. Il est important que nous reprenions contrôle de ces derniers. Les plateformes ouvertes comme Decidim font exactement cela. Ce n'est pas seulement ça qui est open-source (pour que d'autres personnes puissent le forker, le réutiliser et construire un processus participatif). Decidim a également ces valeurs que nous voulons refléter dans notre société codée de la manière dont la plateforme est conçue.
