Decision Table based Rules Engines have been used by a number of states to automate policy since 2000. Deloitte has used this technology in the following deployments^[1]:

• Colorado CBMS
• California CalWIN
• Texas TIERS
• Michigan BRIDGES

Ohio used another Decision Table based Rules Engine in its OFAST project. This project supports corporate audits, which are generally performed by auditors using laptops.

Neither of the previous two code bases were open source projects, and development and general availability of these implementations is unknown.

DTRules represents the third implementation of a Java Decision Table based Rules Engine.
