I have written before about the "Decision Model" book, when Larry Goldberg visited us in HRL.
I met Larry again this week in the OMG meeting, and also had dinner with him and Michael Grohs from KPI in Cary, NC
(I am now staying nearby in Durham -- almost packed to go start the long journey back).
From their testimony it seems that the decision model is catching quite fast, and hundreds of organizations are using it already in one way or another. In the OMG meeting they brought their flagship customer Freddie Mac representative, who reported a big success, there were already several vendors implementing it to be executable. The benefit is the simplicity and riding on the "spreadsheet" table-like thinking with their methodology. They are now working on extending the model which started with partial coverage but is evolving, e.g. they are adding concepts of views and contexts.
Our challenge in event processing is larger, since the complexity of operations is such that I am not sure can be easily expressed in tables, but the seek for abstractions that will enable business analysts and semi-technical users to construct systems is still there. This is one of our activity areas, which I hope to report progress at some time. More - later.
