What’s New in Pega Infinity ’25 and an Insider’s Look into a Global Enterprise’s Business Transformation

The Cost of Staying on Legacy UI and Architectural Models

While the business may feel operational and stable with the legacy model, it often acts as a liability. When we expect to adapt to recent updates, they create technical and operational bottlenecks.  

The Drawbacks of Legacy UI include

In the legacy UI, customization was prioritized over standardization. While these frameworks serve their purpose, they now introduce architectural and operational constraints.

• Legacy UI is not built with strict modular separation. The presentation layers are often embedded within or closely linked to backend logic. Even a minor UI change requires a rule change, and it directly affects the enterprise’s ability to scale within the specified time frame.
• Legacy UI frameworks encourage custom sections, harnesses, and scripts. Over time, standardization becomes difficult. Any upgrades require significant validation effort. The architecture becomes harder to scale consistently across business units.
• They rely on customization like JavaScript injections and rule overrides. Over time, different business units implement variations of similar functionality, leading to inconsistencies across applications.

Constellation as the Architectural Foundation for Future-Ready Enterprises

• Constellation reduces customization dependency: Designed to reduce heavy reliance on custom UI development by prompting a configuration-first, low-code approach.
• Constellation provides model-driven APIs: All UI interactions are powered by DX APIs, allowing seamless integration with external systems, microservices, and enterprise orchestration layers.
• Constellation enables modular, scalable enterprise architecture: Constellation’s decoupled architecture allows experience, business logic, and integrations to evolve independently, supporting long-term scalability and architectural flexibility.

Key Constellation Enhancements in Pega Infinity ’25 for Modern Enterprise UX

Theme editor in App Studio

Developers can now create and manage themes directly in the App Studio. The editor includes a dedicated Colors tab containing all color tokens for a page. This enhancement ensures consistent enterprise branding while reducing the effort required for UI customization.

Intelligent field-level guidance for accurate case capture

This update introduces rule-driven, real-time, field-level contextual messaging, enabling applications to dynamically guide users during data entry based on business logic and runtime conditions.

Built-in UI observability with the Constellation UI inspector

The UI Inspector is an out-of-the-box diagnostic tool in Constellation applications that provides real-time visibility into UI component structure, metadata, and hierarchy, enabling faster debugging and deeper UI observability.

Simplified case views to enable scalable self-service

The standard Case View (used in Work Portal) remains the primary UI definition, from where organizations can selectively include or exclude UI elements.

Turning Pega Constellation Update into Measurable Business Value

Reducing errors in case data capture

Contextual field warnings offer real-time guidance and reduce case errors at the point of capture. It improves the straight-through processing rates.

Built-in UI inspector fixes issues faster

A built-in UI Inspector in Pega Constellation that helps teams see how the screen is built and where problems exist. This helps the users find exactly what is causing a screen issue, thereby saving developer time during troubleshooting. Issues are resolved faster, teams work more efficiently, and the overall cost of maintaining the application decreases.

Simplified self-service experiences reduce service delivery costs

Configurable, simplified Case Views for self-service portals help encourage adoption and reduce dependency on assisted service channels. Every interaction reduces cost per transaction while improving customer satisfaction.
