Recently more vendors such as Sparkling Logic and Signavio announced that their tools now support the DMN standard. They joined the initial DMN implementations provided by OpenRules, Sapiens, and a few others. Nick Broom, a well-known DM practitioner and a contributor to the DMCommunity, provided his review of the Signavio implementation, and promised to provide a review of the FICO DMN Modeler that according to Alan Fish is coming next month – see this LinkedIn post.
We plan to prepare a complete list of the current BR&DM vendors who support the DMN standard. This list along with reviews from practitioners will be published and maintained at this website. If you are a vendor and want to be included into this list, please update your profile at the Live Catalogs of BR and DM tools and email us a link to your implementation.
On May 9, 2015 JBoss Drools announced that they are also “working towards Decision Model and Notation support, that allows networked diagrams of Decision Tables” http://goo.gl/EfJ8zg
DecisionsFirst Modeler (http://decisionsfirst.com) is a DMN-focused decision modeling tool that’s been commercially available for a while, that has a free version for up to three users and that is available both SaaS and on premise.
