SRL Methodology Library provides a concise summary of the key challenges and benefits of adopting a SOA methodology in 3 sentences:
Traditional application architectures have led to data duplication, process duplication, and integration challenges, but adopting SOA technologies without a methodology to guide implementation can exacerbate issues like support complexity and reliability decreases; a SOA methodology addresses these problems by promoting reusable services, improved data and process quality, and clear governance and controls over the SOA lifecycle. Proper implementation of a SOA methodology through incremental stages allows organizations to gain measurable benefits like reduced costs, increased agility, and faster development while avoiding potential downsides of an ad hoc SOA approach.
