The 21st century is characterised by major societal challenges such as climate change, social divisions, and the digital transformation. Although many public organisations have undergone substantial reform over the past 30 years, many are still not sufficiently prepared to tackle these complex challenges. In addition, citizens’ expectations vis-à-vis the public sector are rising, leading to frustration and a loss of trust in institutions if public mangers fail to develop and modernize their organisations. As such, today’s public managers are faced with many difficult questions regarding the role of the state and public administration, organizational strategies and structures, HR, leadership, culture, IT, communication, and their own competencies, skills and managerial methods. In this course, we will reflect on these questions, both from a theoretical and a practical perspective, drawing on the latest international research. Furthermore, we will discuss examples of modernisation initiatives to provide participants with a comprehensive, integrated, and up-to-date management framework to optimise their managerial practices.
