Decision Model and Notation

OMG Specification (version 1.2 published in January 2019)

https://www.omg.org/spec/DMN
-
The purpose of DMN is to
provide the constructs that are needed to model decisions
, so that organizational decision-making can be readily depicted in diagrams, accurately defined by business analysts, and (optionally) automated.
Decision-making⌘
DMN provides Decision Requirements Diagrams:
-
Business process models will define tasks within business processes where decision-making is required to occur
-
Decision Requirements Diagrams will define the decisions to be made in those tasks, their interrelationships, and their requirements for decision logic
-
Decision logic will define the required decisions in sufficient detail to allow validation and/or automation.
Two levels of modeling decisions⌘
