Subject: RE: [soa-rm] FYI: BEA SOA Reference Diagram
There is a good graph from J. Utterbach of MIT Sloan which talks about 3 phases in the evolution of technology: The fluid phase, the mainstream phase, and the declining phase. In the fluid phase, there are many different methodologies/designs/products, etc. that are vying for dominance, but there are only a relatively few actual implementations of the technology. After some amount of time, a dominant design emerges, and the late adopters of the technology start coalescing around this dominant design/method/product,etc. and the other products/methods/designs fall into obsolescence. The final phase is when the technology as a whole is outdated and is displaced by a newer technology. We are in the fluid phase of this technology, and the BEA Reference Architecture is just one of many. It may be good, but it is still just one of many. That's why we are all part of this TC - so we can define somewhat authoritatively (or at least with the appearance of authority) what an SOA is. Part of what gives this group its authority is the fact that many of the players in SOA (including Rag, representing BEA) are in one place hammering this out. -----Original Message----- From: McGregor.Wesley@tbs-sct.gc.ca [mailto:McGregor.Wesley@tbs-sct.gc.ca] Sent: Wednesday, May 18, 2005 2:14 PM To: soa-rm@lists.oasis-open.org Subject: RE: [soa-rm] FYI: BEA SOA Reference Diagram BEA also has a self-assessment tool to determine if your organization is SOA ready. This implies they have a model upon which they derive their outputs. Perhaps our work here is for not as BEA already has the answers :) -----Original Message----- From: Rag Ramanathan [mailto:ragr@bea.com] Sent: May 18, 2005 12:48 PM To: John Harby; SOA-RM Subject: RE: [soa-rm] FYI: BEA SOA Reference Diagram I am one of the original authors of this.
