Decision Model and Notation (DMN) Fundamentals

Our Decision Model and Notation (DMN) v1.1 Training program provides both comprehensive and focused training for DMN. The training is about making business analysts, business architects, and decision modeling teams capable of defining and maintaining the decision logic that runs the business.

Duration: Classroom - 2 Days | Virtual - 4 Days
Why Take This Course:

DMN 1.1 is a new industry standard for rules-based business decision modeling. A DMN model can diagram the structure of a business decision end-to-end and detail the decision logic in the form of decision tables and literal expressions. Our DMN training is about making business analysts, business architects, and decision modeling teams capable of defining and maintaining the decision logic that runs the business. The training covers all five of DMN’s key elements:

  • Decision Requirements Diagrams (DRDs)
  • Decision tables
  • FEEL, DMN’s standard expression language
  • Boxed expressions, DMN’s standard graphical format for decision logic
  • XML model interchange, using DMN’s standard format

Our DMN training shows you how to model business decision logic end-to-end… and test the outcome using input data values you provide.

  • Our DMN Method and Style Basics class shows you how to create complete decision models using DRDs and decision tables.  Like all our courses, this one is hands-on, loaded with in-class exercises.  
  • Our DMN Method and Style Advanced class leverages the full power of FEEL and boxed expressions, the things that make DMN as powerful as today’s proprietary rule languages.  It requires a bit more technical savvy than Basics, but it is still aimed at business users, not programmers.
Learn How To:
  • Describe the purpose and benefits of DMN.
  • Describe at a high level the DMN framework and match where the DMN used in the process models using BPMN 2.0
  • Discuss the essential decision modelling and notations components, steps and ingredients that are necessary for success.
  • Discover appropriate elements of processes that need to be documented.
