In developing countries, the informal sector with its modest but resourceful trading activities is increasingly expanding. Broadly speaking, management is weak in this sector, and basic management training is needed. To make management training valid in the informal sector, time planning, the active participation of the beneficiaries in the needs analysis, and integration of training with other types of support are necessary. Results of a case study of five pilot seminars show that management training in the informal sector is possible. A set of 80-90 pedagogical drawings for an overhead projector has been successfully tested at those seminars. The color drawings convey very simple management messages on women involved in income-generating activities in the informal sector. A trainer's manual is used with the drawings. An analysis of the costs of the seminars indicates that the average cost per participant is reasonable--$30. A weakness of the seminars has been evaluation. Future seminars should study turnover, profits, and employment. (YLB)
