This guide has been developed by the Australian Public Service Commission (APSC) to assist agencies to implement the APS Framework for optimal management structures (the Framework). The Framework has three parts: PART A outlines the context and benefits of change. It also describes how the Framework was developed. PART B describes the Framework, providing design principles and benchmarks for organisational layers and direct reports. PART C provides guidance to agencies on how to implement the Framework.
