DELMIAWorks supplier ratings need event and correction history

Define the supplier-event population before calculating

The direct answer is to make the rating denominator and scope visible. Identify the supplier legal entity, manufacturing or shipping site, parent or affiliate relationship where relevant, commodity, part and revision, purchase and receipt population, date basis and time zone, reporting period, business unit and facility, eligible event types, excluded events, source systems, extraction time, and accountable owner. A supplier name plus a score cannot show what was measured. ^[1]

Receiving inspection, late delivery, rejection, scrap, deviation, concession, return, supplier RMA, corrective action, certificate issue, and lot traceability can describe different objects and clocks. Decide which events count, how partial receipts and split lots behave, whether buyer-caused delays are excluded, how severity and quantity are represented, and what happens when one event spans periods. Preserve each event identifier so the total can be rebuilt from source records.

Version the formula and comparison basis

A useful rating record names every measure, numerator, denominator, unit, weight, threshold, lookback, rounding rule, missing-data treatment, severity adjustment, target, and rule version. It also states whether the result is a rate, weighted index, status band, trend, or reviewer disposition. A dashboard can compare suppliers only when their populations and rules are sufficiently comparable; otherwise it should expose the difference rather than manufacture one rank.

When the organization changes a weight, threshold, eligible population, fiscal calendar, source mapping, or supplier hierarchy, create a new version and define whether historical periods are recalculated. Preserve the original published result used for a decision. If management wants a restated series, label it separately with the later rule and calculation time so an audit can distinguish what was known then from a current analytical view.

Give corrections and disputes their own history

Quality events change. An inspection result can be corrected, a receipt can be reassigned, a defect can be attributed to design or handling, an RMA can close with no supplier cause, and a supplier can dispute an event or quantity. Retain the original event, source and rating; challenge, evidence and reviewer; accepted correction or rejected challenge; effective date; recalculated result; and every decision notified. Do not delete an event simply because the current score improves. ^[1]

A rating can inform supplier development, incoming-inspection strategy, corrective action, sourcing, allocation, escalation, or audit planning, but each use needs its own authority and criteria. The rating should link to the decision package without becoming automatic proof of supplier approval, disqualification, product acceptance, quality-system conformity, contract breach, or award. Record reviewer judgment, conditions, exceptions, and follow-up.

Test one late corrected lot across two periods

Create a representative supplier with two sites, two parts, split receipts, one late shipment, a receiving-inspection rejection, an approved deviation, a supplier RMA, and a later correction that moves an event to another period. Change the formula version between periods and let the supplier dispute cause attribution. Reviewers should reproduce both ratings, every included and excluded event, rule version, correction, disposition, and downstream decision from source records.

The DELMIAWorks page supports the attributed embedded-QMS and listed quality capabilities. It does not establish a customer's data model, supplier identity, event population, formula, rating accuracy, correction process, audit trail, decision, implementation, compliance, or outcome. Manufacturers and their quality, procurement, supply-chain, engineering, finance, data, compliance, and legal owners retain those decisions. ^[1]

Enterprise buyer test

Translate this change into the exact population, record type, workflow stage, decision owner, effective date, and evidence that could be affected. Ask current or prospective providers to demonstrate the named workflow with representative data and an exception—not a polished feature tour. Record what official documentation establishes, what a provider states, what the team observes, and what remains unresolved.

A defensible review also identifies the dependency outside the product. Authority interpretation, policy configuration, data quality, integrations, human judgment, approval rights, release governance, training, and retained evidence may remain customer or service responsibilities. The evaluation should preserve those boundaries instead of treating a technology claim as the complete operating model.

What we will watch next

Quality Systems Index will watch the named source and affected market records for later evidence that changes status, scope, availability, implementation timing, workflow consequence, or the limits of the initial report. A later announcement does not silently overwrite this dated account; the change ledger preserves the sequence.
