"A strong enterprise architecture program is vital if SOA is to reach its potential of actually operating across the enterprise rather than being isolated in individual custom application development projects," says Westbrock.

The ability of service-oriented architecture to rapidly assemble new applications and orchestrate multiple solutions comes from a commitment to reuse. But for that to work, it must be implemented enterprisewide, say the three internationally known, former META Group analysts.
