In many industries, strategic alliance has proved to be important means to gain competitive advantage and to sustain it. Relationship among organizations should be considered in the term of Supply Chain Management. Previous researches about Supply chain pointed the needs of information sharing to solve inefficiency problems like bull-whip effect related to uncertainty between participants.
Especially in the retail industry, the lack of information sharing between retailer and supplier results high inventory handling cost, sales loss, customer dissatisfaction and so on. Inter-organizational information system (IOS) is required to be implemented among different organizations for this reason.
What processes and information should be considered to build IOS between retailer and supplier? What characteristics should be considered and be supported by the IOS? For these questions, this thesis provides two dimensions to make contingency framework in retail process. One of the two dimensions is relationship intensity and the other is task type. Each shared information characteristics and information sharing method is researched in the contingency model. Research model of this thesis will be applied to a real retail case and be observed by exploratory case study.
