the Finesse Server Administration page in CCE deployments allows for the configuration of both Routing Layouts and Skill-groups. Routing Layouts are used to define the layout of the contact center by specifying which agents are assigned to which skills, while Skill-groups are used to create collections of skills that can be assigned to agents. Reason Codes and Workflows can also be configured via the Finesse Server Administration page, but Routing Scripts cannot.
