Accelerate Refactoring: Reduce required application expertise with TAZ and WCA4Z

Using Test Accelerator for Z, a senior developer begins by recording a key business transaction inside the CICS region.
 This recording automatically captures every COBOL program and map involved in that transaction — providing a live visual map of how data and logic flow through the system.
Once the recording is complete, it becomes a powerful artifact — the perfect input for Watson Code Assistant for Z’s Refactoring Assistant.
 Here, AI reveals the hidden architecture behind that business flow, showing precisely which COBOL programs drive which parts of the transaction and how they interact with DB2 tables or copybooks.
For the new developer, the complexity of discovery is replaced with clarity — an instant, AI-assisted view of dependencies, data flows, and business operations.
 The synergy of TA for Z and WCA for Z reduces the need for deep, domain-specific expertise and accelerates onboarding dramatically.
Experienced developers can now focus on business-critical innovation, while early-tenure developers can contribute confidently — all through an intelligent, visualized, and test-driven understanding of the application.
