Perhaps, the most essential part of the knowledge of R&D personnel for our purpose is the knowledge of industrial problems and social demands. It is in this respect that R&D institutions in the developing countries are not very strong. While undertaking technology-development projects, there is great need for being fully abreast of the felt needs and technological requirements of industry. No effort can bear fruit unless fairly realistic statistics are available on the national resources, be they raw materials, human skills, financial resources, etc. The indigenous technology-generation efforts start in the developing countries usually on the basis of an import-substitution model. Any effort to select, redesign and improve upon a process cannot bear any fruit if it is not feasible economically. It is clear that this feasibility assessment can be achieved only if the reliance is made on the national resources.
