A study of 100 managers at Information Technology and e-commerce companies in three districts of Dar-es-Salaam, Tanzania's largest city, identifies the principal factors impeding the spread of e-commerce in that area. These include budget constraints, poor Internet penetration, a low level of computer literacy, and a lack of skills and training. By addressing these issues, along with users' security and privacy concerns, organizational leaders can help foster the adoption of e-commerce technologies that can lead to increased efficiency, profits, and market reach.
