This study aims at enhancing the effectiveness of diverse regulations in relation to participatory decision-making techniques. A conflict resolution tool unfamiliar with Koreans and heterogenous to their traditional culture, the participatory decision-making techniques remain uncovered for most of Korean public services except three local administrations. That's why this study tries first to clarify its concept as it is widely accepted in the related literature and, second, to conceive of its possible alternative model in Korean fashion. Three cases corresponding respectively to three techniques already experimented in three Korean local administrations constituted here the empirical field of qualitative observation : scenario workshop, citizen jury, and regulation negociation. As a final and practical output, this study suggests a checklist of twenty variables to consider in the eventual implementation of participatory decision-making techniques in Korea and this, in three steps.
