With the goal of supporting new process modeling best practices faster than before, while still keeping the number of metamodel variants low, we will support two standard metamodels going forward.

The Unified Configuration Best Practice will represent a clearly structured and consistent version of the Unified Configuration that reflects our best methodological recommendations for process modeling.

• This metamodel is intended to become the recommended foundation for modeling new processes and new process versions.
• Customers using this standard metamodel will receive a “state‑of‑the‑art” metamodel with every release, ensuring optimal process modeling in Stages.

The Unified Configuration Compatibility Mode will continue to include elements and associations that are no longer part of the Best Practice modeling approach, for example Work Product Parts.

Since existing processes were modeled using these elements, continued metamodel support is required.

• This metamodel is intended to be used for past or existing process versions or for migrating processes to the Best Practice metamodel.
• For new modeling activities, the use of the Unified Configuration Best Practice is strongly recommended.

The option to use customized metamodels and to define a customer‑specific metamodel strategy will remain available.
