David McKenzie of the World Bank puts it another way. He finds “the need for more intensive training programs that have larger effects on business practices.” Small firms with fewer than ten employees outnumber large enterprises in developing countries, and their likelihood of surviving and growing is greatly enhanced when they know how to perform better stock-keeping, recordkeeping, and planning, which may result in less spoilage and less downtime that comes from not having the right parts or goods. That, too, is intensity of use.
