How are user interfaces designed in Pega applications?

User interfaces in Pega applications are designed using the Pega App Studio, which provides a visual and intuitive environment. This approach allows developers and business analysts to leverage a wide range of pre-built components, templates, and widgets to create user interfaces efficiently. The use of Pega App Studio ensures that the design is consistent across different applications, adheres to best practices, and promotes usability.

The various components available in App Studio include drag-and-drop functionalities, which simplify the design process, allowing users to focus on the overall architecture and user experience without getting bogged down by the complexities of coding. Pega's UI design capabilities also support responsive design principles, ensuring that applications function seamlessly across different devices.

While other methods mentioned may incorporate coding or external tools, they do not harness the integrated features and user-friendly capabilities of the Pega App Studio, which is specifically tailored for building Pega applications. Thus, the employment of Pega App Studio stands out as the most effective and streamlined approach for designing user interfaces in a Pega application.
