Pega's Center-out business architecture

Traditionally, applications are designed either from the top-down perspective, meaning application design is based on the delivery Channels, or from the bottom up, meaning the application is designed around data storage and access systems.

Pega's Center-out business architecture is customer-centric and focused on delivering business outcomes. It gives meaningful results fast, and sustains the architecture into the future by avoiding the mistakes of both the top-down and bottom-up approaches. 

Pega's Center-out approach puts the business logic layer at the center of application design. This business logic layer maintains all of the information needed to successfully achieve the business outcome. The presentation and data access layers are kept separate from the business logic, ensuring that delivery Channels and database access can be altered as necessary without disturbing the functionality of the application itself.

There are five principles associated with the Center-out business architecture, all organized around the customer and the strategic outcome:

1. Manage intelligence centrally: Business outcomes should be guided by real-time customer information; rules are consistently enforced, and every recommended action is on target.
2. Focus on outcomes, align your process: Use Case Management to manage, automate, and improve work by applying a Microjourney™ approach that implements a part of the customer journey that is tied to a specific outcome.
3. Connect experiences up to your Channels: Keep the front-end logic and back-end logic coordinated. Changes are dynamically reflected without recoding.
4. Connect down to your data, keep logic nimble: Pega allows users to quickly and easily define the data required to build the apps they need and then access that data in their running application – all without having to worry about how and where the data is stored and accessed.
5. Manage variations to be scale-ready: Pega helps organizations adapt to different customer types, lines of business, geographies, and more. Scale big and broad, and stay future-proof by using Pega's Situational Layer Cake™.
