Client Profile
A global enterprise in the financial services sector was operating a heavily customized mainframe environment built over decades using COBOL, PL/I, IMS/DB, and CICS. As the complexity and size of their applications grew, the existing processes and tooling no longer supported the agility and quality standards demanded by the business.

The Challenge
The client faced increasing operational inefficiencies due to:
- Manual Development and Deployment Processes
Most of the development lifecycle—from coding to testing and deployment—relied on
manual tasks, causing delays, inconsistent results, and high error rates. - Poor Visibility into Application Interdependencies
With a vast codebase built over many years, understanding dependencies across modules
and subsystems became nearly impossible, delaying change impact analysis and increasing
risk. - Outdated Tooling and Lack of Scalability
Legacy tools could not support modern development practices like automation,
collaboration, or DevOps pipelines, limiting the organization’s ability to innovate and scale.
Our Approach: A Tool-Driven Modernization Framework
To address the above pain points, VRNexGen Technologies designed and executed a comprehensive
modernization roadmap, combining best-in-class IBM tools with proven transformation expertise:
- IBM Developer for z (IDz)
We introduced IDz to standardize and modernize the development environment. It allowed
developers to benefit from intelligent editing, debugging, real-time syntax checks, and team
collaboration—all integrated into an Eclipse-based IDE. - IBM Application Discovery and Delivery Intelligence (ADDI)
Our team utilized ADDI to visualize and analyze codebase relationships, dependencies, and
execution paths. This enabled faster onboarding, improved change impact analysis, and
empowered developers to make confident modifications. - IBM Dependency Based Build (DBB)
To bring true DevOps into the mainframe pipeline, we implemented DBB to automate
COBOL and PL/I build processes. This minimized manual intervention, accelerated testing,
and integrated seamlessly with CI/CD tools like Jenkins and Git.
The Results
- 40% Reduction in Development & Deployment Cycle Time
- 80% Increase in Developer Productivity and Tool Adoption
- Enhanced Codebase Transparency
- CI/CD Readiness on Mainframe
