What is a harness in Pega?

In Pega, a harness serves as a container for UI presentation, which encompasses the layout and design elements that users interact with. It defines how the various sections of a user interface will be rendered and facilitates the overall user experience by organizing the presentation of information and controls.

Harnesses are integral to the visual design of applications in Pega, allowing developers to specify which sections, user interactions, and controls are to be displayed. This means that all aspects of a user’s interaction point—such as retrieval and input of data, as well as navigation—are handled within the harness. The use of harnesses contributes significantly to creating a cohesive and user-friendly interface, enabling Pega applications to effectively meet user needs and business requirements.

Other options do not relate directly to this specific functionality of harnesses. For instance, while data storage is an important concept in application design, harnesses are not responsible for storing data. Similarly, report generation features are separate functionalities within Pega, not linked to the UI presentation layer managed by harnesses. Lastly, security protocols pertain to safeguarding data and application processes but do not have connections to the presentation layer that harnesses uniquely provide.
