Intermediate SOA maintenance and evolution

By the 2010-2011 time period, many organizations had started the paradigm transition to using service-oriented architecture (SOA), but few had competed that transition. In that time period, most organizations were intermediate somewhere between started and completed. While they were in that intermediate status and beginning to get some of the benefits of SOA use, they continued to have to maintain the legacy software that was still in use, as well as maintain the new SOA-using software. Each of the varieties of software also sometimes needed to be evolved to better meet the needs of the organization. The maintenance and evolution could be affected by the technologies, software tools, and governance that had been used, as well as by changes in them, and by new ones, such as SoaML and the Cloud. Avenues for additional research abounded.
