Introduction What, then, are we to conclude from the rich diversity of experiences presented in this book? The most obvious point to note is that there are no straightforward answers to the question of how to enhance the developmental impact of NGOs. There are strong arguments for adopting all, or any, of the strategies represented. But each strategy faces significant obstacles that must be overcome if it is to be effective, and the efficacy of each can be challenged by critical counter-arguments. There is, therefore, no such thing as an ‘optimal’ strategy for all NGOs, even given similarity in context and background. This does not imply that all choices are equally valid, for NGOs have considerable ‘room for manoevure’ in their decisions and there will be more and less effective approaches for achieving impact in particular situations.
