Supplier Quality Management Software: Scorecards to SCARs

By Josh Brook on October 30, 2026

supplier-quality-management-software-scorecards-scars

Most plants know their worst supplier by reputation, not by data. Rejects sit in the receiving log, SCARs live in email threads and on-time delivery hides in the ERP, so the monthly supplier review turns into an argument instead of a decision. Supplier quality management software pulls those records into one scorecard per supplier and ranks who needs attention first, which you can see on sample data in a 30-minute walkthrough.

SUPPLIER QUALITY HUB · BUYER SIDE

Know Which Suppliers to Act On First, and Why

iFactory's Supplier Quality Hub scores PPM, on-time delivery and SCAR response time automatically from your receiving and purchasing records. Suppliers answer 8Ds in a portal, and AI ranks every supplier by risk so buyers and quality engineers spend the week where it counts.

The Buyer-Side Loop: Approve, Measure, Correct, Develop

Supplier quality is a loop, not a form. A supplier is approved for a defined scope, its deliveries are inspected and scored, problems become SCARs, audits check the system behind the parts, and the results decide whether you develop the supplier or move the work. Software earns its place when each step feeds the next automatically instead of waiting for someone to copy numbers between spreadsheets. Our support team can map your current loop before any setup.

APPROVED SUPPLIER LIST

An Approved Supplier List That Records Scope, Not Just Names

ISO 9001 clause 8.4.1 asks you to set and apply criteria to evaluate, choose, monitor and re-evaluate external providers, and to keep records of those evaluations. AS9100D goes further. It expects a register of external providers showing approval status, such as approved, conditional or disapproved, and the scope of each approval, such as a product type or process family. A supplier approved for machining is not automatically approved for heat treatment. Receiving reads the same list, so parts from an unapproved scope are stopped at the dock. See a scoped register in a live demo.

SUPPLIER SCORECARD AND SUPPLIER PPM

Four Measures, Each With a Formula Anyone Can Check

A scorecard is only trusted when a supplier can recompute it from its own records. Keep the formulas plain, write them into the quality agreement and score every supplier the same way. Weighting is a policy choice, so show each measure on its own before blending them into one score. The worked example uses illustrative quarterly figures for one supplier. Ask our supplier quality team to review your formulas.

Supplier PPMRejected parts ÷ parts received × 1,000,000
On-time deliveryLots received inside the agreed window ÷ lots due × 100
SCAR response timeDays from SCAR issue to an accepted root cause
Repeat defectsDefects of a type already closed, returning within six months
S-04 parts received this quarter48,000
Parts rejected at receiving84
PPM84 ÷ 48,000 × 1,000,000 = 1,750
On-time delivery37 of 40 lots = 92.5%
SCAR responses3 issued, all 3 root causes accepted late

Ask Which Supplier Needs You This Week

The Supplier Quality Hub keeps every score current as lots arrive and SCARs move. Ask in plain language and the AI ranks suppliers by risk, then shows the lots and SCARs behind each rank.

BuyerWho should I deal with before the quarterly review?
iFactoryS-04 and S-05. S-04 is at 1,750 PPM with 3 root causes accepted late. S-05 is over its PPM target for a second quarter, mostly solder bridging, with 2 late responses.
BuyerS-03's PPM looks fine. Is it a problem?
iFactoryQuality is fine, but 2 SCAR responses are past due. Chasing them now keeps S-03 out of the top-right box.
SCAR PROCESS

Let the Scorecard Decide When a SCAR Is Raised

Many SCAR programs stall because the decision to raise one depends on who is on shift. Tie the trigger to the scorecard instead. A repeat defect, a reject on a special characteristic or a PPM breach raises the request automatically, the supplier answers the 8D in a portal, and the response clock feeds straight back into the score. The bars below are illustrative. See trigger rules working in a short demo.

SUPPLIER AUDITS

Audit Where the Scores Point, Not on a Fixed Rota

A fixed rota spends the same effort on a steady fastener supplier as on a struggling heat treater. Risk-based planning brings audits forward when scores slide and stretches the interval when performance holds. In automotive supply chains, VDA 6.3:2023 process audits rate every question on a 0, 4, 6, 8 or 10 scale and grade the overall result, with downgrade rules for serious gaps. Our audit specialists can help you set the triggers.

A · 90% or more
Capable. Usual response: keep the normal interval.
B · 80 to 89%
Conditionally capable. Usual response: dated action plan and a follow-up audit.
C · below 80%
Not capable. Usual response: immediate actions and a status review.
Three audit types, three questions

A system audit asks whether the quality management system works. A process audit asks whether one line or special process is under control. A product audit asks whether finished parts meet the drawing and spec. Match the audit type to the signal on the scorecard.

SUPPLIER DEVELOPMENT BEST PRACTICES

Develop the Supplier, or Move the Work?

Supplier development costs engineering time, so spend it where it pays back. A capable supplier with one weak process is usually worth helping. A supplier that misses SCAR dates, fails audits and resists sharing data rarely changes because you asked again. Make the call on evidence and record it on the approved supplier list. Talk it through with our supplier quality engineers.

Worth developing
  • Problems sit in one process, not everywhere
  • SCAR responses arrive on time, even if weak
  • Management shows up to reviews
  • Shares process and inspection data openly
  • Hard or slow to replace for this scope
Time to re-source
  • The same defect returns after closed SCARs
  • Due dates slip with no explanation
  • Audit actions stay open past follow-up
  • Data arrives late, partial or not at all
  • A qualified second source already exists

SUPPLIER QUALITY MANAGEMENT SOFTWARE IMPLEMENTATION GUIDE

Load These Six Records Before Anything Else

You don't need perfect data to start, but you need the right records in the right order. Begin with suppliers that ship critical characteristics or carry the largest spend, then widen the scope. Clean up supplier IDs first, because duplicate records split one supplier's rejects across two scorecards. Ask our implementation team for a starter data list.

1 · Supplier masterIDs, sites, contacts and parent companies
2 · Approval scopesStatus and scope for every supplier
3 · Receipts and rejectsTwelve months of lots, quantities and NCRs
4 · SCAR historyIssue, due and closure dates for each request
5 · Audit historyResults, open actions and next due dates
6 · ThresholdsPPM targets, delivery window, SCAR due dates
SUPPLIER QUALITY MANAGEMENT SOFTWARE COST AND ROI

Price the Hours Supplier Rejects Already Cost You

Start with the cost you can count: the hours your team spends handling supplier rejects. Every input below is assumed and only the arithmetic is real, so swap in your own figures before quoting any number. Our team can fill it in from your receiving records.

Rejected lots per month30, assumed
Hours per rejected lot: sorting, NCR, SCAR follow-up6, assumed
Loaded labour rate$58 per hour, assumed
Handling hours per month30 × 6 = 180 hours
Handling cost per month180 × $58 = $10,440

That figure leaves out scrap, line stoppages and premium freight. Add those only where your own records support them, and measure how far the handling hours fall once scoring and SCAR follow-up run automatically.

FREQUENTLY ASKED QUESTIONS

What Buyers and Quality Managers Ask About Supplier Quality Software

What does supplier quality management software do?
It keeps the approved supplier list, receiving results, scorecards, SCARs and audits in one place and links them. A reject at receiving moves the supplier's PPM, a late SCAR moves its responsiveness score, and both feed the risk rank that tells buyers and quality engineers where to act first.
How is supplier PPM calculated?
Divide the parts rejected by the parts received over the same period and multiply by one million. For example, 84 rejected out of 48,000 received gives 1,750 PPM. Agree with suppliers whether you count by parts or by lots, and how sorted or reworked parts are treated. You can see the formula run on sample data in a short session.
What should an approved supplier list include?
At minimum the supplier, what it is approved to supply and its status. AS9100D expects a register showing approval status, such as approved, conditional or disapproved, and the scope of approval. Adding the basis for approval and the next re-evaluation date makes the list useful in audits. Our support team can share a starter layout.
How often should suppliers be audited?
There is no single interval. Many teams audit high-risk suppliers and special processes every year and stable, low-risk suppliers less often, then bring audits forward when PPM, delivery or SCAR scores slide. Customer requirements in aerospace, automotive and medical devices may set their own minimums. Record the reason for each change of interval so an auditor can follow the logic.
Can suppliers see their own scorecard?
Yes. Each supplier sees its own scores, open SCARs and due dates in the portal, and nothing about other suppliers. Seeing the same numbers you see usually improves response times without extra chasing. Walk through the supplier portal with our team.
How long does it take to get started?
The full system is delivered turnkey and goes live in 6 to 12 weeks. Most plants start with the suppliers that ship critical characteristics, load twelve months of receipts and SCARs, then widen to the rest of the supply base. Book a 30-minute demo to plan your first scope.
