Re: [service-orientated-architecture] What is SOA?

[Steve Jones]

With the clarification that "cheaper" means TCO and includes ROI (i.e. if I spend $2m and my support costs drop by $500k pa and we make an additional $800k pa).

The test is this. Is it cheaper to keep doing things the way you are doing
them, or is it cheaper to create additional services that support automation and
decoupling of business processes from the systems. When its cheaper to refine
your systems and better support the business through services that wrap the
systems, then you still don't have the "right" SOA. When it's cheaper to stay
where you are at, then you have the right SOA.
