The 5 Big Differences between Decision Models and Business Rules

What’s the difference, and why does it matter?

This article featured on BPM Institute and written by Larry Goldberg answers one not-so-simple question: “how will adopting the Decision Model different from what we’re doing now, and why are those differences important?” The answer takes quite a long, detailed article to answer, starting with common business rules approaches and common hurdles faced by businesses as well.

The article then focuses on the five most important differences in the decision model, including:

  1. Formal notion of decision
  2. Formal model
  3. Model-based functionality
  4. Decision model-based software innovator
  5. Pure business audience driven

Definitions of Decisions

Each of these differences is explained later, as demonstrated by this explanation of the formal model:

The Decision Model, as a new model, is the result of rethinking the problem and learning from history.  It brings to the world of business rules a well-defined structure based on the inherent nature of logic, extended with integrity and normalization principles.  This is similar in concept to what the Relational Model brings to the world of data.

The Decision Model, despite its rigor, is a step towards simplicity.  Simplicity implies that a decision model represents business rules and logic using only a few, familiar concepts.  While based on theory, anyone can understand a decision model even if unfamiliar with its theory.  The combination of simplicity and solid theory makes it valuable and long lasting.

Each explanation is accompanied by a “why it’s important” bullet list, which is quite helpful in showing the reader why they should be interested in the differences.
