Decision Modeling Community of Practice

Join MISMO's Decision Modeling CoP!

The Decision Modeling Community of Practice facilitates and promotes the creation and interoperability of business decisions within the mortgage industry. The group provides best practice guidance on how to satisfy common mortgage industry use cases, and we demonstrate how to seamlessly incorporate the MISMO data model in the creation of decision models.

This is done using the Decision Model and Notation (DMN), an OMG standard that defines how rules are expressed as decision points within a business process. DMN facilitates the creation, maintenance, discussion, publication and exchange of decision models between trading partners by defining a common visual modeling language to represent decisions. DMN decision models may be directly executed by platforms that conform with the DMN standard.

Decision models expressed using the Decision Model and Notation standard naturally use terms from the MISMO Business Glossary, and decisions expressed in DMN are included in business processes from the MISMO Business Reference Model. The interaction will naturally adapt as new work groups are established. Finally, the Decision Modeling Community of Practice works closely with MISMO Education to both present an overview of DMN and its place in the mortgage industry and then later to focus on decision modeling best practices using DMN.

If you are interested to participate with this group and are already a MISMO member you may join the collaboration site that has been established on "MISMO Connect".
