Is anyone reaping the benefits of SOA? At a well attended Catalyst Conference session called "SOA: Dreams vs Reality", a show of hands showed no hands. Anne Thomas Manes, VP & Research Director, went on to provide some tips:
SOA is about design, not technology (as a corollary you don't need ESB or a vendor's latest product to do SOA)
You cannot buy SOA, you must design it
Cultural and political factors are significant impediments to SOA implementations
SOA is a long-term journey. If your organization is not willing to make a significant investment (enterprise-level planning; infrastructure & governance; organizational and cultural shift), don't waste your time.
