James Taylor's Decision Management

Mike Gilpin had an interesting post on the Forrester blog this week - The Four Classical Elements Of The Digital World: Process, Service, Event, and Information. You should take a look at the post - it's an article really - as Mike makes some great points about the interconnectedness of all things in application development. I am particularly interested in this as Mike has invited me to attend the Forrester IT Forum in Las Vegas in a couple of weeks where I will be participating in a few things and blogging about the experience over on the Smart (enough) Systems blog - you can subscribe to get the blog posts from the event as I write them.
To keep you going though, I would make a couple of quick observations around decision management and Mike's ideas. Firstly, considering the digital business architecture he references, one can and should clearly regard the logic of decisions, and the models of analytically derived information, as part of the metadata core. Secondly I see decision services as a subset of all services. Decision services provide decision making to processes, decide how to act on events, and decide using information. In this sense they are the subset of services that, perhaps, most embodies the interconnectedness Mike discusses.
I wrote before on the role of business rules in building a digital business architecture.
