BUSINESS PROBLEM

A large national retirement fund managing millions of members faced critical risks in its multi-year modernization of a legacy COBOL-based recordkeeping platform.

Challenges:

  • Program Execution Risk: Testing significantly behind schedule, limited visibility, poorly coordinated vendor dependencies.
  • Legacy System Complexity: Heavily customized COBOL system, 1,500+ release notes, undocumented customizations.
  • Environment Transition Risk: Migration from UNIX to Linux, compiler/runtime upgrades, behavioral inconsistencies.
  • Data & Operational Risk: High-volume financial transactions, uncertain reconciliation and historical replay accuracy.
  • Governance Gaps: Ineffective accountability, misaligned business/IT priorities, insufficient escalation pathways.

The combination of these risks threatened program delivery, financial accuracy, and regulatory compliance.

OUR SOLUTION

Enterprise Iron applied a Diagnose → Design → Deliver approach to stabilize the program and accelerate delivery.

  1. Diagnose: Establish Ground Truth
    • Assessed testing maturity, customization risk, environment parity, and governance effectiveness.
    • Conducted SME interviews, release note analysis, and transaction flow reviews.
    • Outcome: Clear, evidence-based view of program gaps, replacing assumptions with actionable insights.
  1. Design: Build Practical Execution Strategy
    • Testing Overhaul: “Year-of-history” transaction replay using real data; prioritized high-value scenarios.
    • Test Harness Framework: Automated, reusable transaction-driven tests to improve repeatability and regression coverage.
    • Environment & Platform Strategy: COBOL runtime consistency, file handling validation, infrastructure tuning.
    • Governance Reset: Defined roles, KPIs, escalation paths, steering committees, and cross-functional alignment sessions.
  1. Deliver: Execute & Accelerate
    • Embedded mixed SME and technical teams to expand test coverage and stabilize cycles.
    • Categorized defects (platform, customization, environment) for faster resolution.
    • Optimized performance for batch processes and file access patterns.
    • Implemented operational readiness with end-to-end traceability.

Key Achievements:

    • Rapidly improved testing coverage and defect detection.
    • Strengthened governance and decision-making processes.
    • Enabled reliable, production-ready validation of complex financial transactions.

RESULTS & CLIENT BENEFITS

Program Stabilization:

  • Reduced execution risk and uncertainty.
  • Delivered measurable progress with clear visibility.
