A period of rapid change entails the continual reassessment of problems and values. Some years ago, therefore, it was felt necessary to analyse questions pertaining to the place of the Red Cross in the world today and its role in the future. In 1972, the ICRC and the League, in co-operation with the National Societies, decided to look ahead by studying the situation of the Red Cross from all angles. A joint committee was created for reappraisal of the role of the Red Cross; then, in 1973, the director of what came to be known as the “Big Study”, Mr. Donald D. Tansley, aided by a number of research workers, and with the support of the relevant departments of the ICRC, the League and the National Societies, began his investigations.
