What is the first action a system architect should take after creating application overlay and access groups?

After creating an application overlay and access groups, the first action a system architect should take is to create operators for the portal. This step is crucial because operators are the users who will access the application, and establishing their credentials and roles ensures that users can log in and utilize the functionalities provided by the application.

Creating operators effectively links the identity of users to the permissions and access levels defined in the access groups. This foundational setup allows for a clear understanding of who can access what within the application, which is essential for proper security and user experience as development progresses.

The subsequent steps, such as building adaptive models, setting up performance indicators, or defining propositions, depend on having operators already defined, as these elements typically relate to user interactions and performance assessment based on the behaviors and characteristics of the designated operators.
