The Application Signature Tool provides the automated, evidence based current state metadata that Pega Blueprint ingests to generate a high-fidelity Blueprint, making it the foundational input for fast, accurate modernization. 

Use the Application Signature Tool at the very start of any modernization initiative to quickly and accurately discover how the application works today, and to generate the Blueprintready input needed for safe, fast, AI-powered reimagination. 

When should the Application Signature Tool be used? 

You should use the Application Signature Tool whenever you need to understand the true current state of a heritage Pega application before modernizing it. This is the first and most critical step in the modernization journey because Blueprint and GenAI can only reimagine an application accurately when discovery is complete and evidence based.

What makes the Application Signature Tool essential?  

• It gives Blueprint a complete, accurate snapshot of the current application 

The tool automatically extracts metadata—Case Types, Data Models, workflows, integrations, Personas—directly from the running application. 
This creates a high fidelity, standardized kit that Blueprint can ingest immediately. 

• It replaces months of manual discovery with minutes of automation 

Blueprint needs a correct understanding of the existing app to reimagine it. 
Manual discovery is slow, inconsistent, and often incomplete—especially with older, complex, or poorly documented apps. 
The tool automates discovery in minutes, producing reliable input for Blueprint. 

• It turns legacy complexity into clarity that Blueprint can act on 

Older Pega apps often contain: 

• buried logic 

• outdated flow rules 

• limited case structure 

• partial upgrades that mask real complexity 

The tool exposes the true current state, giving Blueprint clarity for redesign and modernization. 

• It gives Blueprint actionable, AI-ready information 

The tool’s output becomes the foundation for: 

• AI-assisted case redesign 

• AI-driven workflow proposals 

• modernization microjourneys 

• incremental rebuilds based on real usage

Without this structured input, Blueprint cannot confidently propose modernization paths. 

• It removes blockers that prevent clients from modernizing 

Most organizations don’t know what’s really inside their older Pega apps. 
The tool removes this blocker by providing an evidence-based, repeatable view of reality—exactly what Blueprint requires to proceed. 

• It accelerates modernization and reduces risk 

Because Blueprint starts from facts—not assumptions—the modernization journey becomes: 

• faster 

• safer 

• more predictable 

• easier to phase
