ABSTRACT
The effectiveness of individual projects that seek to bring about sustained and wide-ranging social, institutional and technological change increasingly depends on coherent sectoral and macro policies to create a conducive basis. If these policies are not coherent, projects operate with high frictional losses, tie up many scarce resources unnecessarily and all too often fail to set dynamic processes in motion, leading at best to reasonably effective physical structures and isolated increases in productivity. The great disillusionment when success does not materialize also depresses the helpers.
