⚠️ The Challenges You’re Facing Today
The Reality: 60% of COBOL developers will retire by 2026. Your team is already stretched thin, and finding replacements is nearly impossible.
Impact: Increased maintenance costs, delayed enhancements, business risk
The Reality: Adding new features takes months instead of weeks. Integration with modern systems is complex and risky.
Impact: Competitive disadvantage, missed market opportunities, frustrated stakeholders
The Reality: MIPS costs keep increasing. Hardware maintenance is expensive. Specialized tools require costly licensing.
Impact: Budget pressure, reduced ROI, difficult cost justification
The Reality: Mainframe applications can’t easily scale, integrate, or adapt to changing business needs.
Impact: Business process limitations, poor customer experience, operational inefficiencies
The Reality: Critical business logic is trapped in decades-old code. Documentation is outdated or missing.
Impact: Risk of knowledge loss, difficult troubleshooting, compliance challenges
The Reality: Legacy security models don’t align with modern standards. Audit trails are complex to maintain.
Impact: Compliance risks, security vulnerabilities, regulatory concerns
