These technical briefs focus on manufacturing on a small-scale. It is an important livelihood for many people in the developing world and businesses are usually run by a family or a small group within the same community.
Technical briefs are documents produced by Practical Action which are freely available to people in the developing world. They provide detailed technical information on a variety of subjects ranging from how to make jams and pickles to how to build a flood-proof house or an aerial ropeway.
As excellent secondary sources of information students can use technical briefs for research and to analyse and evaluate raw data. They are therefore excellent support materials for the new science national curriculum.
