Background Making system functionality available via multi-channel access (MCA) can be achieved through exposing functions and business processes as software services. When offering MCA to a business process, system performance is an important consideration due to network limitations and verbose messaging in service-oriented technologies. Aims The first aim of this study is to investigate the potential impact on system performance and agility that may occur when an underlying business process is exposed for MCA. The second aim is to investigate if reengineering a system as a service-oriented architecture (SOA) improves agility. The work also aims to create an MCA reengineering method to transform systems from single-channel into multi-channel. Methods A case study was used, along with an experiment, to compare the performance and agility of native language calls (NLC) and protocol based messaging (PBM) for service messaging in a business process. The case study also investigated if reengineering a system as an SOA improves agility by comparing system and code metrics. A multi-channel access reengineering method (McARM) was created and evaluated.
