Model plans negate the real benefit of a planning process - the socialization, mutual learning and role acceptance that is gained when people come together to develop a plan for their organization. That phrase is taken from FEMA's CPG 101 v. 2, which is already an excellent document to help jurisdictions create plans. Perhaps it could be adapted to a lighter version suitable for the schools/IHEs/houses of worship audience. At most, a model outline (which is already in CPG 101 v 2) is useful to help jumpstart work, or maybe a repository where organizations can share their finished plans to provide inspiration, but I'm strongly against creating "model plans" that end up being boilerplate templates that short-circuit the planning process.
