Participatory planning works to include all points of view in the decision making process, and gather them all into one vision.
Being deliberative involves being motivated by an intended outcome and choosing a vision that is based on sound evidence and reason.
[1] According to Diane Hopkins, deliberative planning has three main parts: "the motives behind involving citizens in decision-making (Philosophy); the design and dynamics of the decision-making (Process); and the intended and actual outcomes of deliberative planning (Outcome).
"[2] These three steps are ultimately intended to involve the majority of the community, and the largest stakeholders for the proposed development.
[4] In computational programming, the idea of being deliberative focuses on understanding planning, intent, and motivation to achieve the desired result.
