The Decision Model and Notation (DMN) Standard offers something no previous attempt at standardization of decision modelling did: a simple, graphical effective language for the documentation and modelling of business decisions. It defines both the syntax and the semantics of the model, allowing IT and Business teams to “speak the same language”. It also ensures interoperability between vendor tools that support the standard, and protect customer’s investment and IP.
It was an honour to work with accomplished author Bruce Silver to write the “DMN Cookbook“, a book that explains the features of the standard by examples, showing solutions for real modelling problems. It discusses what DMN offers that is different from traditional rules authoring languages, as well as how to leverage its features to create robust solutions.
Topics covered include:
- What is DMN?
