Once in a while you come across something interesting and I recently came across this Report from Bloor Research which does a good job of covering Business Rules Landscape.

In that report you can find:

• A quick introduction of what rules are and the drivers for using BRMS technology
• Key market issues
  • Repository requirements
  • Development environment requirements
  • Runtime environment requirements
  • Management environment
  • Standards
• Vendor landscape (24 vendors in all) with the following breakdown
  • Stand-alone chargeable
  • Stand-alone free
  • Expert System
  • Part of an application ro infrastructure package
  • Part of a BPMS suite

They also use an equivalent to the Gartner Magic Quadrant called the “Bullseye” to give an overview of the vendor landscape.

Overall a good source of information, free to download if you register on the Bloor Research Web Site.

Here is the link to the report
