This book concentrates on strategic foresight in the German public sector. It shows the principles of strategic foresight: the terminology, organisational localisation, key problems, implications, and the methodology of strategic foresight. The approach of the book uses three methods. The first method is a comparison of the public and private sector in general and strategic foresight specifically to find public sector specifications and to show how the public sector can take advantage of the private sector's strategic foresight practices. The second method is the degrees of freedom diagram that assesses the capability of public institutions to make their decisions independently from third parties by the legal structures used most often in the German executive branch. The third approach is the identification of relevant key success factors of strategic foresight activities in public institutions through a literature analysis.
