Abstract. Developing global leadership competencies is crucial for organizational success in
today’s interconnected world. Despite extensive theoretical discussions, practical insights remain
limited. This study aims to bridge the gap between theory and practice by exploring how companies
implement and measure Global Leadership Development Programs (GLDPs). We interviewed 75
global HR managers from Germany, Austria, and Switzerland through qualitative analysis using the
grounded theory methodology. Our findings reveal effective strategies for developing and
appraising global leadership competencies (GLCs). We discovered that feedback and direct
observation of behavioral changes post-program are the most common evaluation methods. Our
research provides actionable insights and key propositions to help organizations design impactful
GLDPs and apply our theoretical framework across various contexts. This study not only enhances
understanding but also offers practical tools for fostering global leadership excellence.
