The ongoing information revolution is perceived as a profound organizational challenge for foreign ministries. Yet there is only scant empirical evidence on the nature of the change dynamics. Anchored in new institutionalist approaches in political science, this book reconceptualizes diplomacy as an institution of the modern state order and identifies its key organizing principles maintained by the global group of foreign ministries. With this conceptualization as a point of departure, the book provides a comparative analysis of information technology effects in the foreign ministries of Canada, Norway and Slovakia. The result is a comprehensive assessment of the magnitude and the direction of change in the organizational machinery of diplomacy in early 21st Century.
