Which of the following tasks do system architects regularly perform related to rules?

System architects play a critical role in defining application requirements, which is integral to the overall design and implementation of systems within the Pega platform. This task involves identifying and documenting what the application should achieve, including specific business needs and user expectations. By establishing clear requirements, system architects ensure that the application aligns with business objectives and can effectively leverage the available rules to meet those needs.

Defining application requirements sets the foundation for the rules that will govern system behavior, helping to create a structured approach to rule management and governance throughout the development lifecycle. It ensures that rules are not only effective but also relevant to the business processes the application is designed to support. This task requires a deep understanding of both business logic and Pega's capabilities, allowing for the creation of rules that streamline operations and enhance user experience.

While auditing business processes, monitoring project timelines, and managing user permissions are all important tasks in the development lifecycle, they do not specifically center on the creation and definition of rules, making them less directly related to the primary responsibilities of system architects in this context.
