"This document provides definitions, guidelines, and uses of the Public Safety Architecture Framework (PSAF). [...].The SAFECOM process for identifying and developing standards began with the Public Safety Statement of Requirements (PS SoR). Those requirements are driving the vision for a migration from current as-is architectures to the future to-be interoperable public safety communications enterprise architecture. The Public Safety Architecture Framework (PSAF) provides an industry-validated enterprise architecture methodology to plan and develop the migration from current public safety architectures to the interoperable systems outlined in the PS SoR. [...]. PSAF Volume II contains detailed descriptions of the three PSAF views and the products that create each of the views."
