Decisions made easy with DMN (Decision Model and Notation)

Making a well-founded decision is not always easy, especially in day-to-day business life with numerous procedures and models. To simplify decision-making, the introduction of clear rules can help. But how do you map complex choices so that they are clear for everyone? The Object Management Group (OMG) has addressed this issue and developed a new method that enables clear decision-making - the Decision Model and Notation (DMN).

What is DMN and how does it help my organization?

Models in companies are complex, and underlying decision-making is correspondingly even more complex. Which is the right one and how can all relevant factors be taken into account in the decision-making process? To ensure that the right choices are made, especially in everyday work, and that these decisions are also comprehensible and reproducible by all others, it is central to introduce clear rules and to document them. A simple representation of decisions with common modeling notations can of course support here. However, the more complex the business rules, the more confusing the model might become. It is therefore advisable to use a method that is precisely designed to represent complex decisions clearly within models and at the same time to take all relevant decision rules into account: the OMG's Decision Model and Notation (DMN) is an approach that creates a strong impact for common decisions for your management and decision makers but also your entire business knowledge.

Finally bringing clarity to your decision-
making with DMN

The central goal of decision modeling is to map models with complex choices in a simple and comprehensible way. Thanks to this approach, employees and management are enabled to understand decisions that have been made, thus creating more transparency and clarity by using decision models and the resulting analysis. Decisions with DMN are made on the basis of Decision Requirement Diagrams and Decision Tables. Decision rules are represented graphically within a Decision Requirement Diagram. The Decision Table acts as a supplement and enables a more detailed analysis of decision-making in the DMN model. The use of these models provides your employees and especially your decision makers the possibility to reproduce decisions across departments, to improve communication to your customers and to further expand your analytics.

Where is the DMN used?

The DMN is utilized in various industries. Here is an overview of some use cases:

Industries	The DMN can be used to model decision logics for the following use cases:
Insurance	Risk assessment, claims settlement, and insurance premium calculations
Finance	Loan approvals, investment strategies, and risk management
Healthcare	Diagnosis and treatment decisions, as well as patient management
Logistics	Route planning, warehouse management, and inventory management
Energy	Demand management, load management, and tariff structuring
Telecommunications	Tariff planning, network configuration, and billing processes
Automotive	Product configuration, maintenance plans, and warranty processing
Education	Curriculum, student counseling, and admission processes

What are the elements in the DMN?

The DMN consists of the following five elements:

Decisions

The central element in the DMN is the decision (also called output), which is determined depending on input data, the business knowledge model and knowledge source. The decision logic retrieves one or more business knowledge models.

Input data

These denote information that must be considered in the decision-making process and/or the business knowledge models. Input data can include, for example, customer data, order information, or product characteristics.

Business Knowledge Models

A business knowledge model maps business knowledge in the form of decision tables, business rules, and analytical models, among others.

Knowledge Sources

Decisions or business knowledge models can be based on authorities such as subject matter experts, or source documents from which the business knowledge models are derived. A knowledge source represents the source of expertise on which the business knowledge models are based.

Decision Service

The Decision Service is a top-level decision that defines reusable logic within the decision model. This ensures centralized management and reusability of the decision logic. It uses inputs, business knowledge models, and other sources of knowledge to make decisions and feed back the resulting outcomes.

The perfect symbiosis: DMN and the BIC Platform

You want to finally tackle decision-making in your company? No problem with the BIC Platform! In our web-based modeling software BIC Process Design, the DMN is available as a stand-alone notation, making decision modeling and analysis easy. On its own, the decision models provide a wide range of functions to support the decision logic. If you want to further optimize and extend this, a combination of DMN and BPMN 2.0 models is useful.
Less complex decisions can be modeled as gateways and activities within BPMN 2.0 - but if the decisions become more complex, this approach reaches its limits and an addition of DMN is advisable. Decisions that are difficult to understand are simplified and decision tables are effortlessly integrated within a BPMN diagram.

The pure decision modeling is not enough for you and you finally want to take the step towards automation? By adding the BIC Process Execution software, you pave the way to complete digitization of your business and decision models. The decision tables created in BIC Process Design serve as the basis for this. In our powerful zero-code software BIC Process Execution, these rules and decisions are then transferred from modeling to automation and turned into executable processes at the push of a button. You can then easily enter decision-relevant criteria in digital forms and the tool will automatically show you the right decision based on the stored rules and your models. Automated decision-making based on DMN will significantly help reduce errors, simplify business processes, and ensure better compliance overall. Take your models and IT to the next level and get started today with the right software by your side!
