Decision Model and Notation (DMN)

Decision Model and Notation (DMN) is a standard published by the OMG, Object Management Group. It is a standard approach for describing and modeling repeatable decisions within organizations.

Why Model Decisions?

There is an emerging consensus that a Decision Requirements Model is the best way to specify decision-making. Decision Requirements Models can and should be developed in an industry-standard way using the Object Management Group’s Decision Model and Notation (DMN) standard. Adopting this industry-standard gives users access to a broad community and a vehicle for sharing expertise more widely.

Today business analysts use a variety of techniques to accurately describe the requirements for an information system. However, current requirements approaches don’t tackle the decision-making that is increasingly important in information systems.
