Which of the following is NOT a main focus of the Pega Business Architect?

A Pega Business Architect primarily focuses on aligning business objectives with the capabilities of Pega's platform, rather than on the technical aspects of software development. This role is centered around understanding business needs, identifying opportunities for improvement, modeling business processes, and ensuring that the solutions delivered provide tangible business value and benefits.

The emphasis on assigning business value, considering business benefits, and promoting rule reusability are all integral aspects of a Business Architect's responsibilities. They are required to engage with stakeholders to ensure that the solutions designed not only meet technical requirements but also deliver measurable outcomes that enhance the business processes.

Technical design implementation is typically the realm of developers or technical architects who focus on the coding, configuration, and system integration aspects. Therefore, this choice stands out as not being a primary focus for a Business Architect, who is more involved in the strategic and business-oriented elements of Pega implementations.
