This document provides guidance on developing a proposal for a new policy or program within a target organization. It recommends including background on the current state of the relevant existing policy or program, challenges it faces, and senior leadership's views of it. The proposal should then outline the proposed solution and resources already reviewed from the target organization and other cities to build the conceptual foundation. It should also list planned future resources and interviews to further develop the plan, along with addressing questions about stakeholders, pitching the plan for buy-in, defining success, and potential impacts.
