A highly successful network of Intermediate Technology Transfer Units has been established within Ghana, serving to foster and develop small-scale, informal industry. Since the founding of the first ITTU in 1980 the idea has flourished with such units being set up throughout Ghana. This handbook provides detailed guidelines on the workings of the unit. Whilst its primary purpose is to serve as a training manual for those involved in the operation of ITTUs, it also aims to introduce the idea to a wider audience, perhaps inspiring others to reproduce the practice elsewhere.
