Decision Model and Notation™ (DMN™)¶
Welcome to our comprehensive guide on Decision Model and Notation (DMN). This documentation is designed to take you from the basics of decision modeling to advanced deployment scenarios, providing both theoretical knowledge and practical examples.
What is DMN?¶
Decision Model and Notation (DMN) is a standard approach for describing and modeling repeatable decisions within your organization. DMN provides business analysts and technical developers with a common notation that is readily understandable to both audiences.
With DMN, you can:
