This guidebook "is the second book in the APEX Guidebook series and is designed to help correctional practitioners deepen their knowledge of the Public Safety Model domains. It offers practical suggestions for improving performance and creating positive change by sharing best-practice methods and current literature on higher performance in corrections" (p. ix). APEX itself provides strategies for achieving performance excellence in the Public Safety Model domains-operations (which includes safe and secure supervision and settings and process management), stakeholder focus, workforce focus, strategic planning, measurement/analysis/knowledge management, and results. Eight chapters follow an introduction to Achieving Performance Excellence (APEX): introduction; operations focus-safe and secure supervision and settings; operations focus-process management; stakeholder focus; workforce focus; strategic planning; measurement, analysis, and knowledge management; and results.
