There are two analyst articles I'd like to point out today. The first is "Rules the IBM ILOG Way" by Simon Holloway from Bloor, and the second is "Business rules technology belongs in your architecture" by Mike Gualtieri from Forrester. Nothing groundbreaking if you follow this space, but both useful articles for newcomers.
Slightly older (not sure how I missed this -- I must have my head down too much!) is Eric Charpentier's excellent hands-on introduction to some of the new features in JRules 7.
