Is SOA a fundamental change in the way we do business?

SOA represents a fundamental shift in how businesses approach technology and system integration. Rather than building monolithic applications, SOA encourages breaking business capabilities into reusable, interoperable services that can be orchestrated to meet changing business needs. This affects not just technical architecture but also business processes, organizational structure, and how IT aligns with business goals. It changes how companies think about software assets, reuse, and agility.
