Your ERP, MES, PLM, QMS and CMMS each hold part of the record, and few plants run all five. The work is resolving what they separately know into the context the person in front of the decision actually needs, without quietly overwriting the system of record for any of it.
Match an incoming order against the drawing revision, BOM and routing it references. A called-out tolerance, material or finish that does not correspond to the current revision is flagged to engineering before the production order is released, so the discrepancy surfaces at intake rather than on the line.
Pull the lot history, inspection records and CoAs behind an NCR, draft the initial root-cause narrative, and keep CAPA documentation traceable in the QMS to the controlled revision it came from, so the audit trail is a by-product of the work rather than a second job.
Bring together asset history, alarms, prior corrective work orders, preventive-maintenance records, parts history, manuals and technician notes so the person diagnosing a fault has the relevant history in one place, with operating conditions attached rather than remembered.
Trace an engineering change across the BOMs, drawings, work instructions and downstream manufacturing records it affects, and surface anything still operating against a superseded revision. What gets released, and when, stays a controlled decision.
Compare incoming certificates and inspection results against the approved specification, the control plan and the supplier requirements that apply, including PPAP records where the customer requires them. A deviation is packaged with its receiving inspection record so receiving and quality can decide what happens to the lot.
Read a line stop against the work order and routing it happened on, gather the open orders and downstream operations it blocks, and separate what is genuinely halted from what is merely behind. The expedite call then rests on shop-floor data rather than on who escalated hardest.
A production order releases against a superseded revision because the ERP and the PLM were updated on different days. Routing changes lag the engineering change that caused them, so a work instruction can be perfectly correct for a part that is no longer built. Inspection results arrive as a PDF or a screenshot of a supplier portal and cannot be queried at all. Maintenance history lives partly in the CMMS and partly in a technician's own notebook. And the person who knows why a machine drifts out of tolerance every third week is holding the process together with knowledge that has never been written down.
An ERP for orders, the BOM and purchasing; an MES for execution on the floor; a PLM for revision control and released engineering data; a QMS for non-conformance and CAPA; a CMMS for assets and preventive maintenance. Not every plant runs all of them, and some run two of the same kind side by side. The records that have to line up across them: BOMs, drawings and routings; engineering changes; work instructions and production orders; NCRs and CAPAs; control plans, supplier documentation and CoAs; and work-order and maintenance history.
Operations absorbs it as exceptions: an expedite or a line stop decided on a partial picture, because assembling the full one means opening three systems and interrupting two people. Quality absorbs it as reconstruction, rebuilding lot genealogy and root cause by hand for each NCR, then producing documentation that has to demonstrate which revision it applied to.
Early conversations are free and low-pressure. If AI isn't the right tool for the job, we'll say so.
