✨What is DMN or Decision Model and Notation? What are the benefits of it?
Decision Model and Notation (DMN) is an open standard from OMG for modeling business rules and decisions. It allows users to model business rules and decisions by combining multiple components:
🔹Decision Requirement Diagram, or DRD, is a visual representation of a decision that allows modeling a multistep business decision. In this diagram, you specify outcomes, inputs, and requirements of decisions using Input Data, Knowledge Sources, Business Knowledge, and, of course, other Decisions.
🔹Boxed Expression is a model that represents complex decision logic in nested and tree structures. There are several types of Boxed Expressions.
🔹Friendly Enough Expression Language of FEEL is an expression language for specifying runtime behavior of the models on calculations and collections and other operations
🔹Decision Table is where you define your business rules in a tabular and structured manner using conditions (inputs) and actions (outputs).
All of these components go hand in hand to model and execute business rules and decisions.
🤔Why is the DMN standard important? Such standardization did not exist a couple of years back. Every vendor had (and still has) its own way of modeling business decisions and rules. I see two major benefits in this standard for modeling and executing business rules and decisions:
1️⃣ Interoperability: Like all industry standards, interoperability is at the core of the benefits of supporting Decision Model and Notation (DMN). For instance, in a Business Process Management solution that has the ability to define rules but not complex decisions and business rules, you can now simply drag and drop a DMN package, and it executes the DMN model that you built in a Decision Management Suite that supports the full extent of DMN to create very complex decisions and business rules.
2️⃣ Migration: As the users and companies want to adopt decisioning technologies, it is easier to migrate from older systems if they support DMN. Even if the old one does not support DMN, the migration process becomes easier by capturing decisions and rules in DMN and bringing them to a new platform.
3️⃣ Finding talent and training staff: Standardization makes finding talent easier, so talents who know the standard and have worked with it can be hired. Training internal staff also becomes easier because there are loads of articles, tutorials, etc., about the standard. Although the implementation of them still depends on the vendor's capabilities, it is better than nothing.
