Overview

The DMN Method and Style course not only shows how to create model-based decision requirements but also how to develop fully executable DMN services that address real-world project needs. This DMN course shows how to model business decision logic from start to finish, and how to test outcomes using input data values.

The course is utilizing the Trisotech Decision Modeler, a component of Trisotech’s Digital Enterprise Suite. Throughout the course, students use the tool to create examples and engage in exercises where they model specific scenarios. Afterward, solutions are reviewed and discussed. This practical, hands-on approach is the most effective way to learn DMN.

The course content received a major update in March 2022 to incorporate new features from the Trisotech platform (v11) and the DMN standard (v1.4), as well as to meet the demands of Low-Code Business Automation. The updated course merges what was previously two separate courses, DMN Basics and DMN Advanced, into a single comprehensive program. Additionally, this DMN training serves as a prerequisite for Low-Code executable process design in Trisotech BPMN, which leverages boxed expressions and FEEL from DMN.

Training Delivery and Certification

The primary delivery format for the DMN Method and Style training is self-paced web/on-demand, using videos with accompanying exercises using the Trisotech Decision Modeler, a component of Trisotech’s Digital Enterprise Suite, a cloud/browser-based tool. This format provides full DMN training based on the proven Method and Style approach, complete with individualized post-class certification.

Key Learning Objectives

In this course, you will learn the following aspects of DMN:

  1. Logic decomposition with Decision Requirements Diagrams (DRDs)

  2. Decision Table hit Policy and Decision Table Analysis

  3. Low-Code logic design using standard tabular formats called boxed expressions

  4. User-defined functions, known as Business Knowledge Models (BKMs)

  5. FEEL, a powerful yet business-friendly expression language for formulas in table cells, including:

    • Variables and datatypes

    • Literal expressions with string and number functions

    • Calendar arithmetic

    • Lists and tables

    • Input data validation

  6. Contexts, a boxed expression type that simplifies FEEL expressions

  7. Testing logic by executing it in the tool

  8. Defining and publishing decision services for execution by external clients

Intended Audience

Contrary to popular belief, DMN is not “too complicated” for business users. If you can create reasonably complex Excel spreadsheets using the Formulas ribbon, you qualify as a “maker”. We assume no prior knowledge of programming or decision management techniques.

The Method and Style approach is designed for business analysts and architects, enabling them to use DMN to create decision models and manage the deployment of business decision services to drive process outcomes, and align business operations with strategy.

What is included

The web/on-demand training includes the following:

  • Approximately 10-15 hours of instruction, assuming all exercises are completed

  • 60-day access to the Trisotech platform, including DMN tools

  • In-class exercises using the tools, with interactive discussion about the solutions

  • PDF student notes

  • Post-class certification based on an online exam and a mail-in exercise, involving one-on-one interaction
