Decision Model and Notation (DMN)

DMN is a decision modeling standard from the Object Management Group (OMG) intended to provide a graphical notation for specifying business decisions. The notation is intended to support both business users and technical developers in the authoring and execution of decision models. The notation is based on the concepts of the decision table, which is a widely used technique for representing decision logic.

The OMG released the first version of the DMN standard in 2015. The standard defines a family of decision models, including the decision table, decision tree, and decision rule model. It also defines a notation for expressing decision logic, using a combination of graphical elements and textual expressions.

The DMN standard is designed to be used in conjunction with the Business Process Model and Notation (BPMN) standard. BPMN is a widely used standard for modeling business processes, and the two standards are intended to be complementary.

What is DMN used for?

Decision Model and Notation (DMN) is a standard from the Object Management Group (OMG) for modeling decisions. It provides a graphical notation for representing both the structure and the behavior of decisions.

DMN models can be used for a number of purposes, including:

- Automating decision-making processes
- Documenting decision-making policies
- Analyzing and improving existing decision-making processes

DMN is particularly well suited for modeling complex, real-world decisions that need to be made by humans or software systems. Examples of decisions that can be modeled using DMN include:

- Loan approval
- Fraud detection
- Customer segmentation
- Pricing What is difference between BPMN and DMN? BPMN is a business process modeling notation that is used to model business processes in a graphical way. DMN is a decision modeling notation that is used to model decision-making processes in a graphical way.

What is DMN diagram?

A DMN diagram is a graphical representation of a decision-making process. It can be used to model any kind of decision-making process, from simple to complex. DMN diagrams are composed of a series of interconnected nodes, which represent the different stages of the decision-making process. Each node is connected to one or more other nodes, representing the different options or paths that can be taken at each stage.

What is a DMN engine?

A DMN engine is a decision management system that uses the DMN (Decision Model and Notation) standard to model and execute decisions. DMN is a standard for representing decision logic that is portable across different decision management systems.

DMN engines provide a way to automate decision-making processes using the DMN standard. DMN engines can be used to model and execute simple decisions, or complex decision models that involve multiple stakeholders and decision criteria. DMN engines can be deployed on-premise or in the cloud, and can be accessed through a web-based interface or a REST API.

What is context in DMN? Context in DMN refers to the setting in which an event or situation occurs. It includes the physical, social, cultural, and political environment in which something happens. In order to properly understand an event or situation, it is important to consider the context in which it took place.
