You cannot have one without the other..... business services are all very well and good but when a business service is looked at from the 30000 foot view and we all know that businesses love the word 'automatic' when it comes to IT, you don't get the full benefits of re-use (that is a cornerstone of SOA) if you think of services at the single process-single service level.
And I don't agree about the 'expressed on paper and is never theoretical'.... until something is proved (ie. you;ve gone and done it) it will always be theoretical. 2008/12/24 Michael McGrady <mmcgr...@topiatechnology.com>: > Building analogy: > > View A == SOA is meant to focus on what the building owner wants (business > defined services), including resale values and future modifications.
