- The SCS Framework calls quality the “lifeblood” of continuous improvement—regular performance reviews kindle betterment.

- Achilles adds that a standardized Quality Management System across suppliers helps detect weak points and elevate entire networks.

3. Key Metrics & KPIs for Supply Chain Quality

“To improve what you don’t measure is impossible.” Effective supply chain quality optimization starts with tracking the right metrics—precision tools that spotlight inefficiencies and opportunities for improvement.

Perfect Order Rate (POR)

The percentage of orders delivered flawlessly—correct items, quantity, condition, documentation, and timing.

Formula:
Perfect Order Rate = (Perfect Orders ÷ Total Orders) × 100%

- A “perfect” order meets all these conditions: on-time, in-full, undamaged, accurately invoiced, correct documentation—and more.

- Because it consolidates multiple dimensions, POR offers a holistic lens on customer satisfaction and internal alignment.

Why it matters
- Measures the end-to-end supply chain health in one KPI.

- High POR correlates strongly with loyalty, reduced costs, and operational coherence.

OTIF / DIFOT (On-Time In-Full / Delivery In Full On Time)

The ratio of orders that arrive both complete and on schedule, viewed from the customer's expected delivery window.

Formula:
OTIF = (Orders Delivered On Time AND In Full ÷ Total Orders) × 100%

- Complements POR by emphasizing only “time + quantity.”

- Industry benchmark (e.g., UK retail) often targets >97% at SKU level.

Delivery Schedule Adherence (DSA)

Tracks supplier reliability—how consistently they meet agreed delivery dates and quantities.

Formula:
DSA = (On-Time Deliveries ÷ Total Deliveries) × 100%

- A low DSA results in buffer stock, increased costs, and shortage risk.

- Supports supplier performance evaluation and ranking.

Inventory Turnover

Reflects inventory efficiency—the speed at which stock moves from receipt to sale.

Formula:
Inventory Turnover = Cost of Goods Sold ÷ Average Inventory

- Higher turnover = leaner operation, reduced holding costs.

- Balances order readiness with cost-effective inventory management.

Lead Time Metrics

Types:
- Customer Order Cycle Time: Time from order placement to customer delivery.

- Supply Chain Cycle Time: Time needed to fulfill an order if starting from zero inventory.

Why they matter:
- Shorter lead times = quicker response to customer demand.

- Long lead times can hide quality issues and inflate carrying costs.

Cash-to-Cash Cycle Time

How long cash is tied up—between supplier payment and customer payment.

Formula:
Cash-to-Cash Cycle = Days Inventory Outstanding + Days Sales Outstanding – Days Payable Outstanding

- Quality disruptions (returns, rework) slow this cycle—impacting cash and profitability.

Fill Rate & Perfect Case Fill Rate

Fill Rate: Percentage of customer demand fulfilled immediately from stock.

Perfect Case Fill Rate: Orders shipped correctly on first pick, in full.

- High fill rates = fewer backorders, higher customer trust.

- Poor rate leads to re-picks, increased labor, and unsatisfied customers.

Supplier Quality Performance (SQP) & Return/Defect Rates

SQP: Tracks supplier consistency and defect-free deliveries.

Return/Defect Rate: Percentage of products returned or found defective.

- Both align with POR and OTIF—spotting trouble early.

- High performance here improves margins and brand reputation.

Freight Bill Accuracy & Cost Metrics

Freight Bill Accuracy: Percentage alignment between service and invoice.

Freight Cost per Unit: Average transport cost per unit shipped.

- Ensures transparency and flags billing irregularities in logistics.

Customer Satisfaction Score (CSAT)

Definition: Post-delivery customer surveys score satisfaction related to service, delivery, and quality.

- Though subjective, CSAT often reveals early warning signs when performance metrics dip.

4. Benefits of Optimizing Supply Chain Quality
