DMN Method and Style – New Book and Training Now Available

I've been heads-down for a while working on a new book and training: DMN Method and Style.  The Decision Modeling and Notation standard now promises to transform the world of proprietary decision management software in the same way that BPMN upended the world of workflow, EAI, and business process analysis software a decade ago.  Do [...]

DMN Demystified, Part 8. What’s Not in DMN 1.1

DMN 1.1 is the first implementable version of the standard.  The spec is done, but won't be released to the public until mid-2016.  A lot of work went into it, so people are surprised at all the things that are not in it: Business glossary.  Howls of anguish went out online when it was revealed that [...]

DMN Demystified, Part 7. Conformance Levels

While unifying decision modeling and execution is a laudable goal, OMG realizes not all DMN vendors and practitioners want to do that.  So DMN defines three levels of conformance to the standard.  A tool vendor can implement just a sliver of DMN and still proudly slap that "standards-based" label on their software. Conformance Level 1 (CL1) [...]

DMN Demystified, Part 6. Key Element 5: Metamodel and Schema

All of the conceptual elements of DMN - their names, attributes, relationships to each other, whether they are required or optional, and so forth - are formally defined in the specification by a metamodel, a set of UML class diagrams.  Here, for example, is the metamodel for a Decision: Closely related to the metamodel is [...]

DMN Demystified, Part 5. Key Element 4: Boxed Expressions

Last time I mentioned that FEEL is just an expression language not a programming language.  It does not have statements.  It cannot create variables.  But, of course, you need those to define executable decision logic!  So where do they come from? What makes DMN business-friendly is that variables and their value expressions are created graphically, in diagrams [...]

DMN Demystified, Part 4. Key Element 3: FEEL

If DMN just wanted to be a requirements-gathering notation along the lines of BPMN 1.x, DRDs and decision tables would be enough.  (And unfortunately, to many decision management vendors and consultants, those are enough!)  But DMN has higher aspirations.  Like BPMN 2.0, it seeks to unify modeling and execution in a single language, accessible to [...]

DMN Demystified, Part 3. Key Element 2: Decision Table

A second key feature supported by every DMN tool is the decision table.  In DMN, decision tables are one form of expression used to determine the value of a decision or BKM.  Decision tables have been around for 40 years, but DMN defines specific formats and rules for their construction.  In one common format, the [...]

DMN Demystified, Part 2. Key Element 1: Decision Requirements Diagram

The one part of the spec that every DMN tool supports is the Decision Requirements Diagram, or DRD.  It provides a business-friendly picture of the dependencies of a high-level business decision on supporting information.  Rectangles in the diagram represent decision nodes.  A decision has a name (the label in the rectangle) and a value determined [...]

DMN Demystified, Part 1. Retracing the Path of BPMN

This post is based on a talk I gave at the BBC conference in November. DMN, which stands for Decision Model and Notation, is a relatively new OMG standard.  By unifying business decision modeling and execution, it hopes to do for Business Decision Management what BPMN did for BPM over the past decade, which is [...]
