Overview of Replacing a Champion Model

After reviewing production monitoring reports, you might find that it is necessary to retire a champion model and replace it with a champion model that performs better. You might also find that the project is no longer viable, and you need to retire the project.

You can retire a champion model and replace it with a new champion model that resides in any version folder for the project.

Use the following table to determine the tasks to perform when you retire a champion model:

State of the Champion Model	Tasks to Perform
A new champion model is available in the same version folder	Set the new model as the champion model. Update the model life cycle milestones status as appropriate. Approval of some tasks was based on the previous champion model. Note: If the characteristic or stability analysis shows significant changes, set a new champion model in a different version folder. The bin definition that is used in characteristic and stability analysis is based on the data that was developed for the first champion model that was selected in the version and does not change after it is created. An out-of-date bin definition might cause incorrect characteristic or stability analysis.
A new champion model is available in a different version folder.	Set the model as the champion model. Set the version as the default version.
A new champion model is not available when you want to retire a model but not retire the project.	Set the project State property to be inactive. After a new model is ready, do the following: Set the model as the champion model. Update the appropriate life cycle milestone tasks. If the new champion model is in the same version folder as the previous champion model, ensure that milestone tasks are based on the new champion model and not on the previous champion model. Set the project State property to be active.
No other champion models are planned for the project and the project is to be retired.	Set the project State property to be retired. (Optional) Set the default version life cycle retire status as completed.
