Quality Management Glossary

Clear definitions of essential terms in industrial quality, supplier development, and manufacturing excellence.

8

8D Methodology

8D (Eight Disciplines) is a structured problem-solving methodology used to resolve complex quality issues and prevent recurrence. It guides teams through containment, root cause analysis, corrective actions, and verification.

A

Advanced Product Quality Planning

APQP is a structured framework for planning and launching new products in automotive manufacturing. It ensures product quality by aligning design, process, and supplier readiness before production.

C

Cost of Poor Quality

COPQ (Cost of Poor Quality) is the total cost incurred due to producing defective products or services. In automotive manufacturing, COPQ typically ranges from 3-5% of revenue and includes scrap, rework, premium freight, customer claims, warranty costs, and inspection labor.

F

First Pass Yield

First Pass Yield (FPY) measures the percentage of units that pass through a process without rework or repair. It is a core quality metric for process capability and efficiency.

Failure Mode and Effects Analysis

FMEA is a structured method for identifying potential failure modes in a product or process, assessing their impact, and prioritizing actions to reduce risk.

I

IATF 16949

IATF 16949 is the global quality management system standard for automotive manufacturing. It builds on ISO 9001 and adds automotive-specific requirements for defect prevention, risk reduction, and continuous improvement.

O

Overall Equipment Effectiveness

Overall Equipment Effectiveness (OEE) measures how effectively equipment is used by combining availability, performance, and quality. It highlights losses from downtime, speed, and defects.

P

Production Part Approval Process

PPAP is a structured process used in automotive manufacturing to prove that a supplier can consistently produce parts that meet customer requirements. It requires documented evidence, samples, and approvals before production launch.

R

Root Cause Analysis

Root Cause Analysis (RCA) is a structured approach to identify the underlying cause of a problem, not just its symptoms. It is essential for preventing recurrence in quality systems.

S

Statistical Process Control

Statistical Process Control (SPC) uses control charts and statistical methods to monitor process stability and detect variation before defects occur.

V

VDA 6.3 Process Audit

VDA 6.3 is a process audit standard used in the automotive industry to evaluate product and process quality across the supply chain. It assesses process capability, risk, and compliance using structured questionnaires and scoring.
