Electronic Data Interchange (EDI) automates the transmission of data and documentation across supply chains. EDI has the potential to significantly improve control systems and increase efficiencies in supply chains in Less Developed Countries (LDCs). EDI can enhance regional and international stability by improving access to markets and thus stimulating economic development. However, the adoption of EDI in Africa has not received much attention in control engineering and international stability research. This paper presents findings of a country case-study which used institutional isomorphism theory to draw up theoretical propositions and tests the strength of this theory in explaining EDI adoption in Cameroon. Data was gathered from 26 companies, and findings are presented and interpreted. From this conclusions were drawn about important isomorphic institutional factors that facilitate the adoption of the EDI technology in Cameroon.
