Operator - Anyone who can login into PEGA PRPC system is called Operator. Each of the operators has an Operator ID and password, and they are attached to an access group. Every role has its own portal

Access Group - An access group restricts access to functionality within your application. You can create multiple access groups for the same application to achieve different levels of access control. An access group determines: 1. The portals users can access after they are logged in. 2. The roles, or privileges, available to users.

User Portal - A user portal is the application user’s view into the application. Pega provides several default user portals. Each portal is customized to the needs of a specific type of user.

Harness - A harness organizes the structure of a portion of the user display. In Pega, you use a harness to organize either a work form or a portal. Harnesses that allow users to select a flow action and complete an assignment contain an action area.

There are 4 types of Harness: New, Confirm, Perform and Review
