The Charter's own design (Articles 57 and 63): the founders knew the UN could not be everything — the functional fields (labour, health, food, finance, posts, telecoms) needed autonomousorganisations with their own memberships, budgets and expertise, yet coordinated within the system. Article 57 defines (agencies established by intergovernmental agreement with wide international responsibilities in economic, social, cultural, educational, health and related fields, brought into relationship with the UN); Article 63 empowers ECOSOC to conclude therelationship agreements (the coordination, the exchange, the recommendations' channel). The model's logic: specialisation plus coordination — each agency self-governing, all answerable to the system's coherence (today's coordination through the Chief Executives Board — the administrative machinery).
