Based on multiple case studies in the German Manufacturing Industry, it demonstrates that resource deficits serve as an overriding contingency for the outsourcing decision. However, specific knowledge on internal business processes may lead to production cost advantages for the firm and, thus, inhibits the outsourcing of IS functions. Furthermore, cultural variables like distrust and sociability serve as additional contingencies for explaining heterogeneous outsourcing patterns.case studiesInformation Systemsinterpretivismoutsourcingsocial factorstheory of the firmText/Journal Article1861-8936
