Evolution and Maintenance of SOA-Based Systems at SAS

As SOA-based systems are becoming more common, there is a need to consider how traditional IT roles and responsibilities need to change. This paper proposes a framework for roles that are required for evolving and maintaining SOA-based systems. It builds on work on traditional IT roles, as well as insights emerging from current research on SOA. The paper also presents a questionnaire for collecting data from organizations on roles that they use for SOA-based systems maintenance and evolution. Results from a pilot use of the questionnaire with Scandinavian Airline Systems (SAS) are presented.
