The management of public projects and programs in developing countries is rather disappointing in terms of quality, cost and time. Management does not respect the prescriptions of the intervention matrix and logic recommended by results-based management. Strategic governance is sorely lacking, corruption and misappropriation are frequent. Some projects or programs that have been initiated are abandoned, others are extended and require budgetary additions or counter-cyclical indebtedness. The objective is not always constructed with the stakeholders, including the beneficiary populations, but often imposed by the resource providers. In light of all these shortcomings, strategic management must apply the principles of good governance by rationalizing the intervention logic of projects and programs, by systematically introducing the standards and guidelines of the new public management based on results-based management and pursuing the "3 Es" (Economy-Efficiency-Effectiveness). These developing countries are still looking for structuring projects and programs that generate positive externalities.
