We conduct research on society inclusion to public policy decision-making (at municipal and state level) with the methodology of design-based thinking. The methodology draws on cooperation between stakeholders (municipality or the state and citizens) and experimenting. It facilitates development of empathetic processes and services that are responsive to citizens (residents) needs. Such strategies at municipal or state level promote society engagement into public policy decision-making, increase public trust in governance and strengthen citizens’ respect to law.
