Comprehensive and Detailed Explanation From Pega Robotics System Exact Extract:

In Pega Robot Studio, toast notifications are used to display short, non-blocking messages to users during runtime. These notifications are highly customizable and can be globally managed to maintain consistent branding across an enterprise automation project.

According to the Pega Robotics System Design and Implementation Guide (UI Messaging and Toast Notifications section):

“Toast notifications can be added to the Globals tab of a project to maintain consistent visual and behavioral configuration throughout the solution.

The notification element placed in Globals allows setting properties such as title, duration, color, font, and position that are shared by all automations calling the Show() method.

Automations reference the global toast notification by invoking its Show method from the Globals section of the Palette.”

This means that:

The best practice for ensuring uniform design and branding (consistent colors, layout, font, and position) for toast messages is to define one global toast notification in the Globals tab.

Once the global toast notification is configured, all automations that require displaying toast messages will simply call its Show() method, inheriting the standardized display settings.

Option Analysis:

A. Incorrect — Adjusting the Utilities section does not define reusable toast notifications.

B. Incorrect — The project properties do not include toast formatting controls.

C. Incorrect — Creating an automation to set these dynamically would not enforce consistent styling across all notifications and is not recommended.

D. Correct — Placing a toast notification in the Globals tab allows defining display parameters once and reusing them via the Show() method in automations, ensuring global consistency in branding and formatting.

Therefore, the correct and Pega-recommended approach is Option D.
