What is DMN (Decision Model and Notation)?

Digitalize and automate your operational decisions with the OMG® industry standard.

What is DMN?

Decision Model and Notation

The Decision Model and Notation (DMN) is the OMG® standard for modeling, documenting and automating decisions. Business analysts, subject matter experts and IT professionals use DMN as a common notation that is easy to understand, vendor-independent and widely used. With DMN, companies increase transparency, combine a wide variety of decision-making approaches and drive digital transformation through automation.

Why DMN?

Coding, Spreadsheets & BPMN

Digitalization requires companies to automate their often complex operational decisions. However, they often fail with conventional approaches:

  • Manual decisions based on spreadsheets: Real automation, and thus digitization, is not possible with the common spreadsheet approach.

  • Hard-coding into applications: Programming is an inflexible method resulting in cumbersome changes and maintenance. Often, decision logic is dispersed and redundantly implemented into applications.

  • Embedding decisions in BPMN process models: This approach usually results in chaotic and unclear BPMN models. Besides, decision logic has to be changed much more frequently than process logic which requires a separation of the two parts.

Standardization & automation with DMN

With Decision Model and Notation (DMN), companies standardize and optimize how they define and automate operational decisions. It allows business and IT users to define requirements and implement decision logic collaboratively, e.g. by using decision tables. They benefit from:

  • Graphical and analytical view on decisions and their dependencies

  • Vendor-independent, open OMG® industry standard

  • High flexibility through independency from processes and applications

  • Consistent decisions through reusable decision models

  • Automated execution of decision models


Transparency & Agility

Transparent decision-making processes provide both, clarity to internal stakeholders and traceable compliance to the regulator. Underlying decision models can be changed in a fast, effective and safe way, thus, increasing business agility.

Quality & Profitability

Subject matter experts use DMN to easily and systematically create decision models and define requirements. They uncover how value is created, take risks into account and improve the quality and profitability of their operational decisions.

Efficiency & Consistency

The Decision Model and Notation allows companies to automate decisions that have been made manual before within a process. This way, they implement truly digital end-to-end processes that enable consistent and efficient interactions with their customers.
