Service-oriented architectures (SOAs) promise unlimited agility and organizational flexibility. However, achieving these benefits is entirely contingent upon the ability to effectively manage the SOA environment across the enterprise. This paper presents an overview of strategies and practices for governing the transformation to, and the evolution of, SOA. In particular, it explores the role of governance throughout the SOA lifecycle as well as the technology enablers that help organizations develop and maintain an SOA that delivers measurable, sustainable business value.
