Product
One engineering change, traced through five decisions.
DeltaLedger doesn't replace your PLM or ERP — it connects what each already knows, so supply chain, engineering, and operations leaders can see the financial consequence of a change before it's realized, not after.
01
Engineering
The change is proposed and diffed.
Current and proposed BOMs are imported and compared. A replacement — one part swapped for another — is always paired explicitly by an engineer, never inferred.
02
Procurement
The commitments are made visible.
Open purchase orders, supplier cancellation terms, and exchange rates are brought in alongside the BOM — the commercial fact base exposure is calculated from.
03
Operations
Identity is resolved, exposure is calculated.
PLM part numbers are mapped to ERP part numbers with a confidence score. Every dollar of exposure is then classified — known, estimated, or unresolved — with full evidence behind it.
04
Finance
Mitigation is tracked to a real outcome.
Cancellations, redirections, and negotiated outcomes are recorded against the frozen figures — cost avoided versus loss realized, never blended.
05
Executive
The evidence becomes a decision.
A report leads with the conclusion, then the confidence, then the next step — with every supporting figure still one click from its source.
What this means in practice
Six capabilities, one connected workspace.
Engineering change management
Import current and proposed BOMs and get a deterministic diff. A replacement — one part swapped for another — is always paired explicitly by an engineer, never inferred.
Financial impact analysis
Every dollar of exposure is calculated against real open purchase orders and classified — known, estimated, or unresolved — so a number is never presented with more certainty than the data actually supports.
Cross-functional collaboration
Engineering, procurement, supply chain, and finance work from the same evidence inside one workspace — not a spreadsheet stitched together after the fact from four separate exports.
Decision support & cutover planning
Model different cutover strategies against real on-hand inventory, WIP, and open PO terms, and see the financial and operational consequence of each before committing to one.
Traceability & auditability
Nothing is ever edited in place. Corrections supersede prior records, and every action is recorded in an append-only audit trail — a defensible answer to "how did we get this number," months later.
Reporting
A report leads with the conclusion, then the confidence behind it, then the recommended next step — with every supporting figure still one click from its source record.
