COBOL System Twin — Plan Changes With Confidence
Preview blast radius, window fit, and audit packets using deterministic dependency and lineage maps— without touching production.
What You Can See Upfront
Answer the three questions every change leader asks before a release.
Blast Radius
Programs, copybooks, jobs, and downstream files impacted.
Window Fit
Batch schedule impact and critical path detection.
Audit Packet
Evidence kit: diffs, links, rollback plan, and approvals.
Common “What‑If” Scenarios
Use real graphs and lineage to plan safely.
Field Change
Find all reads/writes, copybooks, downstream reports, and regression hotspots.
Copybook Update
Resolve includes, IO maps, and ripple effects across modules and jobs.
Batch Window Shift
Understand schedule dependencies, critical path, and feasible window changes.
