With the Decision Model and Notation (DMN) standard, the Object Management Group (OMG) is hoping to replicate its signature success story, BPMN. Unlike most OMG standards, both BPMN and DMN are purportedly aimed at business users rather than developers and architects. Business users are notoriously averse to standards, so BPMN’s achievement of high business user adoption is surprising. Naturally, that success has spawned legions of critics as well, who say it’s too complicated for business users, too many icons and symbols, too many rules for what’s correct and incorrect.
