Discover our COBOL documentation & modernization solutions⚖️ Comparison of legacy COBOL modernization approaches
Many legacy COBOL modernization approaches exist, but none combine simplicity, speed, transparency, and automation as effectively as ours, especially for mid-sized organizations.
| Criterion | Traditional approaches | Bosqweb approach |
|---|---|---|
| Implementation | Months-long projects, multiple consulting phases. | Fast setup: audit and COBOL documentation in minutes. 72-hour sprint. |
| Cost | High, time-based, people-heavy. | Clear, scalable subscription (COBOL packs, express audit). |
| Accessibility | Mostly for very large enterprises. | Designed for banks, insurers, public sector, and mid-sized companies. |
| Usability | Expert-only interfaces. | Clear interface for decision-makers and business users. |
| Automation | Heavy manual intervention. | Advanced AI: COBOL mapping, testing, metrics, auto-documentation. |
| Dependencies (call graph) | Manual inventories, heavy graphs. | AI mini-call graph New “This module calls X, Y, Z” — text plus list of critical COBOL dependencies. |
| I/O Mapping | Partial, expert-dependent. | Simplified I/O mapping New Files/DB accessed plus operation type (READ, WRITE, UPDATE) for COBOL jobs. |
| Data lineage | Partial traceability, heavy tools. | AI data lineage New Lightweight COBOL data-flow summaries and diagrams for decisions. |
| Proof & monitoring | Hard-to-use technical reports. | Readable COBOL KPIs: functional fidelity, business equivalence, performance, compliance. |
Tip: these “light” COBOL outputs are designed for quick decision-making and modernization roadmaps. Graphviz/Mermaid exports for COBOL call graphs and data lineage are available on request.
