Misconceptions about SOA:

1) Approaching SOA as merely “another messaging technology for connecting applications.”

2) Thinking of SOA as the latest evolution of object orientation or component based development.

3) Aiming for too much — instead of the right level — of reuse.

4) Focusing on building a “service library” — in which services may or may not be discovered and reused — versus a “service portfolio” attuned to business processes.

5) Treating SOA as a solution, when really it is only an approach — the end-goal of any efforts should not be to simply “build an SOA.”
