If you are kicking off your first BRMS project, don’t start by gathering the rules! Often teams will be advised to begin their business rules project by gathering all the relevant rules, in a natural language or rulebook approach. But these rules-first approaches address issues that don’t exist with modern BRMS technology, resulting in redundant and counter-productive efforts.

A decisions-first, decision modeling approach using the Decision Model Notation (DMN) standard is the best practice for business rules projects when implementing a modern BRMS.
