SOA will fail without governance warns Gartner

Service oriented architecture (SOA) projects will fail unless they are tightly managed and audited, Gartner has warned.

Service oriented architecture (SOA) projects will fail unless they are tightly managed and audited, Gartner has warned.

Addressing an audience of 400 business users and IT heads at the SAP World Tour event in Birmingham, Paola Malinverno, vice president of research at Gartner warned that developers should not be allowed to modify an SOA.

"Public enemy number one is when a developer makes changes to services," instead of reusing code, Malinverno warned.

He said IT directors faced a challenge. "Reuse is not a benefit of SOA but a hurdle that needs to be overcome in order to improve business agility and lower software maintenance," the two main benefits of an SOA.

"The main reason SOA projects fail is because there is a lack of governance." He recommended that IT directors establish an IT integration team to oversee the development of new services.

Malinverno also said that IT directors needed to rethink how a programmer is incentivised. Rather than measuring programmer productivity by the amount of code produced, Malinverno recommended that IT directors put greater emphasis on reuse of web services.

Such a tactic could improve the chances of a company's SOA strategy being adopted, since programmers could be encouraged to reuse existing web services which make up the SOA.

He also emphasised that an SOA was an architecture that needed to support change and was not static. Organisations would have to run impact analyses on early projects as and when services they used were modified.
