EDI통제의 효율성 결정 : DEA 방법론

Abstract

Electronic Data Interchange(EDI) has a significant impact on business parctices by eliminating paper related audit trails and enabling transactions to be processed at high speed without human intervention. Major advantages and benefits derived from EDI, however, depend upon the usage of EDI controls. Management must determine whether their investment on EDI controls is appropriate, as the establishment of EDI controls demends much resources and high skills. This study proposes data envelopment analysis model to identify efficient and inefficient EDI control systems in various context of input (formal and automated EDI controls) and output (EDI implementation and performance). DEA can also determine the factors that are significantly different between efficient and inefficient and inefficient groups. The model is tested using data collected from EDI adopters.
