Built for Real-World Challenges

See how teams use COBOL Graph to tackle their toughest legacy problems

😰

The Scared Maintainer

"I need to change one field and not break payroll."

Context

  • • 2M LOC COBOL system
  • • No documentation
  • • Production outage would be catastrophic

How COBOL Graph Helps

  • • Search variable → see all writers/readers
  • • Visualize execution paths
  • • Generate impact list

Value

ConfidenceFaster approvalsFewer regressions
👔

The Consultant

"I just inherited this system and need to sound smart fast."

Context

  • • New client
  • • 6–12 week engagement
  • • Needs to explain system to stakeholders

How COBOL Graph Helps

  • • System-level dependency view
  • • Exportable diagrams
  • • Data lineage explanations

Value

Faster onboardingHigher efficiencyClear communication
🔧

The Modernizer

"We're not rewriting—yet—but we need to untangle this mess."

Context

  • • Gradual modernization
  • • Coexistence with Java / APIs
  • • High audit pressure

How COBOL Graph Helps

  • • Identify stable vs volatile components
  • • Map interfaces and data contracts
  • • Plan incremental changes

Value

Safer roadmapReduced riskEvidence-based
