The Center-out business architecture is a Pega-specific model designed to optimize business processes by focusing on customer outcomes. It starts with the core of the business—the customer Microjourney—and works outward to the channels of engagement and the enterprise systems of record. This approach avoids the common pitfalls of traditional top-down (channel-specific) and bottom-up (system-specific) designs. By centralizing business logic around the customer journey, it ensures consistency across all channels, accelerates the delivery of business value, and creates a more agile and sustainable architecture.

B: This describes a channel-centric, or "top-down," approach. The Center-out model is designed specifically to avoid duplicating logic in each channel by centralizing it.

D: This describes a system-of-record, or "bottom-up," approach where each system maintains its own data and logic. This creates silos, which the Center-out model aims to break down.

2. Pega Documentation. (2023). The Center-out business architecture. Pegasystems. Retrieved from Pega Community. The documentation states

"The Center-out approach focuses on the Microjourney objectives

identifies when engagement with a channel is needed to complete a step

and determines what data is necessary to complete a step or updates on the completion of a step." This directly supports option C.

3. Pega Documentation. (2023). The Center-out business architecture. Pegasystems. Retrieved from Pega Community. The document describes the "top-down" approach as leading to "inconsistent and siloed channel experiences

" which aligns with the flawed methodology described in option B. It also describes the "bottom-up" approach as creating "data silos

" which aligns with the flawed methodology in option D.
