Steve, Here is a question which Anne put (but I stupidly deleted when I was erasing some junk messages): what do you mean by a "heatmap"? It raises images of infra-red sensory apparatus...

We, probably, have to issue a recommendation (including wining-and-dining) for IT on how to switch their organisations and governance onto thinking in services. It is not a joke or sarcasm.

Why? My guess, it is because they are doing well already, without SOA. Or, their systems are already service-oriented enough for the corporate tasks(!?). > > > > > > > > I understand that "it is much much harder to make sure they are conceptualized , design and coded to stay qualified as re-useable"; this is because SOA mentality has not been accepted "down the line", to the development. We know, this will take time and efforts.

I am working on this right now as well. However, I found that it can be implemented iteratively, i.e. not everything behind GUI should be a service right away. I am talking about 'transition' layer of proxies that to be replaced when the services are ready. As a result, investment into analysis and estimates gets spread over multiple projects for certain period of time and appears as a strategic roadmap. This also wins some time to make up the development minds to think in services. > > > > > > > > - Michael Poulin > > > > > > > > > > > > > > > > > > > > "Sarode, Prashant" <[EMAIL PROTECTED]> wrote: > > > > > > > > > > > > > > > > Interesting comment-'SOA is a lifestyle' > > > > > > > > I just came out of an big program estimation mtg in which I was pointed that the SOA'ziation of program was an expensive life-style and how using 2007 technology we still need all those big hrs to build an system in which various GUI's consume services that we build as part of SOA. > > > > > > > > It is easy to identify re-useable business services w/n an enterprise but it is much much harder to make sure they are conceptualized , design and coded to stay qualified as re-useable after the initial reuse discovery. > > > > > > > > Hence, long and expensive estimates and surprise to non-tech savy as to why it will take longer and more $$'s to do SOA'ization of business solutions. > > > > > > > > Prashant Sarode > > > > > > > > ----- Original Message ----- > > > > From: [email protected] <[email protected]> > > > > To: [email protected] <[email protected]> > > > > Sent: Fri Jan 19 07:29:37 2007 > > > > Subject: Re: [service-orientated-architecture] Schurter on BPM, SOA & Software > > > > > > > > Hmmm. BPM is something you do, not something you buy. Sounds an awful lot like SOA to me. I have plenty of examples of companies that have saved lots of money, improved time-to-market, and reduce application maintenance through proper application of SOA principles.In the process, they also consolidated their application portfolio and gotten a much better handle on their data. But in order to do so, you have to do a fair amount of enterprise planning, pick the right projects, deploy a shared infrastructure, institute a governance program, and change the way people design and build systems. > > > > > > > > SOA is NOT about technology, but technology can facilitate its adoption.
