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.

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.

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.
