What to do when insanity reigns
Q&A: Miko Matsumura on the State of SOA
(Miko Matsumura, vice president and deputy CTO, SOA products at Software AG webMethods)
Khan: "If you had to take a pause and assess the state of the SOA today, what do you see?"
Matsumura: "People have gone through all of the Kubler-Ross stages now and have come to acceptance of SOA. SOA isn't utopian in the sense that Adoption is painful and difficult. We have been through a lot of cycles where people look for escapist alternatives. But when you get down to it, IT System and Organizational sprawl is a disease, and if you don't cure this disease, your IT systems will become ossified, atherosclerotic, and will slowly become the cement boots that will drown your business. People are understanding both that the cure is as painful as the disease, or perhaps even more painful"
Joe McKendrick wrote in August 2007:
How do we really know when SOA ‘fails’?
"Lack of a true SOA...."
"Lack of reuse or sharing by multiple business units...."
"More money spent than gained — over the long run...."
"More, not less, vendor lock-in...."

Anne Thomas Manes recently wrote: SOA vs SOI
Service oriented architecture is hard work. It's disruptive. It's a political minefield. It involves going through the application portfolio and identifying redundant applications that can be decommissioned and replaced by a single service. But no one ever wants to open that can of worms. Many folks live by the adage, "If it ain't broke, don't fix it." There's way too much other stuff to do. But each additional application increases the annual maintenance and operations budget. And for many of those applications, the cost of maintaining the application exceeds the value it brings to the business.

And just for the record, in general, when I find myself sometimes disagreeing with something Anne has written, I carefully review my assumptions and usually find myself altering my conclusions.
