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.
Els principis democràtics com la rendició de comptes, la igualtat i la transparència estan en el centre del disseny. Decidim és està construït tenint al cap la democràcia, és el seu gran focus.

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.

Gràcies a Decidim, hem aconseguit a Barcelona co-produir un pla estratègic de ciutat conjuntament amb la ciutadania. En el 2016 inaugurem el Pla d'Acció Municipal en forma de procés participatiu a través de Decidim Barcelona. Actualment aquest pla recull gairebé 7 mil propostes ciutadanes. Una dels avantatges d'utilitzar aquesta plataforma és que pots seguir en tot moment l'estat d'implementació de les propostes acceptades.
