In addition, because communities are more complicated in their processes of change than individuals are, these researchers also built the Community Readiness Model on social action work done in the field of community development (Warren, 1978). The social action process identifies stages on the community level that lay the groundwork for collective action. Thesestages include Stimulation of Interest, which is the recognition of need; Initiation which involves development of the problem definition and possible solutions via programs proposed by community members; Legitimization, which is when there is acceptance of local leaders of the need for action; Decision to Act, which is the development of specific plans involving members from the wider community; and Action, which is implementation.
