Decision Model and Notation

In <a href="/facts/Business_analysis/yKgTq3Ty">business analysis</a>, the Decision Model and Notation (DMN) is a standard published by the <a href="/facts/Object_Management_Group/SNpN8n9U">Object Management Group</a>. It is a standard approach for describing and modeling repeatable decisions within organizations to ensure that decision models are interchangeable across organizations.
The DMN standard provides the industry with a modeling notation for decisions that will support <a href="/facts/Decision_management/4Y46yN7C">decision management</a> and <a href="/facts/Business_rules/9d4kYkDr">business rules</a>. The notation is designed to be readable by business and <a href="/facts/Information_technology/glMzunwe">IT</a> users alike. This enables various groups to effectively collaborate in defining a <a href="/facts/Decision_model/xB3mM2kh">decision model</a>:

<ul><li>the business people who manage and monitor the decisions,</li>
<li>the <a href="/facts/Business_analyst/NUK8rQHx">business analysts</a> or <a href="/facts/Functional_analyst/NUK8rQHx">functional analysts</a> who document the initial decision requirements and specify the detailed decision models and decision logic,</li>
<li>the technical <a href="/facts/Software_developer/WGTS1Jv9">developers</a> responsible for the automation of systems that make the decisions.</li></ul>
The DMN standard can be effectively used standalone but it is also complementary to the <a href="/facts/BPMN/JQ1w8eWJ">BPMN</a> and <a href="/facts/CMMN/JLTWMn7t">CMMN</a> standards. BPMN defines a special kind of activity, the Business Rule Task, which "provides a mechanism for the process to provide input to a business rule engine and to get the output of calculations that the business rule engine might provide" that can be used to show where in a BPMN process a decision defined using DMN should be used.
DMN has been made a standard for Business Analysis according to BABOK v3.
