Business Process Outsourcing (BPO) represents an organizational change which results in an e-Business relationship between a firm and an outsourcing service provider. This paper analyzes whether and how a modular IT architecture - service-oriented architecture (SOA), in particular - contributes to the potential of BPO by increasing the benefits and reducing the costs. This research question is investigated using a multi-case study approach based on six different firms which have adopted SOA. Three of them have already made BPO experiences based on SOA and all confirm SOA’s positive impact on BPO. Besides identifying success factors, counter intuitive results and new research opportunities are identified.
