What is one of the key benefits of following Pega’s guardrails?

Following Pega’s guardrails offers significant advantages for sustainable application design, which is the primary reason for the correct choice. The guardrails are established best practices that help ensure applications are not only built consistently but also with a focus on long-term maintainability and scalability. By adhering to these guidelines, developers can create applications that are easier to modify and enhance in the future, reducing technical debt and improving overall system performance.

This guidance fosters a design approach that considers future requirements and potential growth, which is essential as business needs evolve. While the other options might suggest some benefits, they do not encapsulate the core value of the guardrails so effectively. For instance, while guardrails can contribute to managing project timelines and resource allocation better, they do not guarantee project deadlines will never be missed, nor do they inherently mean fewer developer resources will be needed. Additionally, while training new developers might be eased by having structured practices to follow, the primary intent of the guardrails focuses more on promoting sustainable application architecture.
