How do leadership tasks change as companies internationalise, and how can companies provide their leaders with developmental opportunities to prepare them for operating within this context? These are questions that are discussed in this book. The background is the growing number of multinational companies and the fact that leadership capacity and capabilities seem to be considered a major prerequisite for success. The book is the result of a common interest and cooperation between academics, researchers and consultants at the NHH (Norwegian School of Economics), the SNF (Centre for Applied Research at the NHH) and the AFF (Administrative Research Institute at the NHH), which constitute the NHH Group. This synthesis of insight from academics and consultants is a unique feature of this book. The book covers theories of leadership and organisation that are relevant to the context of multinational companies (MNCs), empirical findings on leadership and leadership development, and recommendations for designing leadership development initiatives for MNCs. The AFF Foundation was established in 1952 on the initiative of Professor Rolf Waaler at the NHH. Its mission statement reads: To promote insight into leadership and organisations through research and development, consulting and related activities. This can be achieved through the Foundation's own activities, financial support or cooperation with other institutions or individuals. Today the foundation pursues its mission primarily through part ownership of the leadership institute AFF AS.
