Knowledge is essential for decision-making, strategic planning and problem solving1, and national integration is no exception. In order to better the odds of success, integrative policies and strategies must be formulated, implemented and evaluated on the basis of appropriate, accurate and timely information. Information must be obtained on three factors that bear on the success of national integration. First, the reasons why certain integrative strategies succeed in one country and fail in another must be clear. Second, knowledge must be gained of which structures, values, resources and outputs facilitate or hinder national integration. 2 Third, the most effective and prudent methods for evaluating integrative success or failure must be identified. To attempt national integration without this knowledge would be tantamount to navigating a dark labyrinth without a flicker of light.
