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.
Apreciem că este construită pe democrație și, prin urmare, democrația este un obiectiv important. Principiile democratice precum responsabilitatea, egalitatea și transparența se află în centrul proiectării.

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.

Aproape fiecare proces participativ care a ajuns la masa noastră, am reuşit să îl rezolvăm folosind regulile de afaceri ale Decidim. Ca instrument, este unul foarte puternic. Cu toate acestea, partea care ni se pare cea mai puternică şi cea mai importantă este comunitatea sa, atât dezvoltatorii, cât şi cei care o folosesc pentru procesele participative. Coexistenţa cu acestea ne-a făcut să apreciem provocările pe care le implică punerea în aplicare a democraţiei participative în lumea reală.
