Phase 4 calls for securing member commitment. Preliminary member commitment was measured in Phase 2 as potential members were asked to make financial contributions to offset costs for feasibility analysis and other start up costs. Phase 3 calls for a membership survey to further quantify the size of membership and the scale of member business. This information is included in the feasibility analysis. Phase 4 further refines member commitment in terms of equity investment, member risk, members’ rights and responsibilities.
