I'm not a huge fan of Gartner, due to the cash for comments nature of their business, but I thought the following was an interesting piece. Of particular relevance, I found the last point one that I identify with:
"And Gartner's fifth prediction is that by 2012 one-third of analytic applications applied to business processes will be delivered via coarse-grained mashups. IT shops are no longer focusing on grand visions such as SOA, which involve building composite applications out of fine-grained services or portals that merely display operational and analytical information next to each other, the analyst firm explained. Coarse-grained mashups, on the other hand, can be used to overlay analytical insights."
I interpret this, as tactical solutions will be successful, where as big bang solutions will fail. In my experience, that is almost always the case!
