The work provides a concise introduction to the topics of demographic change and demographic-oriented human resource management, divided into six parts. Starting with a brief introductory section on demographic development and SMEs, it is followed by a foundational contribution to demographic-oriented human resource management. Subsequently, a systematic approach to implementing such an HR concept in companies is described, based on a holistic design framework. Building on this, there are discussions on selected action areas of demographic-oriented human resource management. The entire foundational section includes a variety of concrete procedures with practical implementation tools such as checklists, tools, planning tables, software references, workshop concepts, etc. Following this, there is an illustrative practical section with reports from companies.
