Automotive Product Development Glossary

Use this reference to align terminology across product planning, engineering, testing, regulatory compliance, manufacturing, quality, suppliers, and service.

ADAS
Advanced Driver Assistance Systems that support functions such as braking, lane control, parking, and driver awareness.
AIS
Automotive Industry Standards used for vehicle and component requirements in India.
APDP
Automotive Product Development Process: the controlled lifecycle from market opportunity through development, production, and field improvement.
APQP
Advanced Product Quality Planning, a structured method for planning product and process quality across development and launch.
Architecture freeze
Approval of the major vehicle layout, domains, system interfaces, and performance direction for detailed engineering.
BOM
Bill of Materials: the controlled list of parts, quantities, revisions, and relationships required to build a product.
CAE
Computer-Aided Engineering, including structural, thermal, crash, fluid, durability, NVH, and electromagnetic simulation.
CAPA
Corrective and Preventive Action used to contain a problem, remove its cause, verify effectiveness, and prevent recurrence.
CMVR
Central Motor Vehicles Rules governing vehicle-related requirements in India.
Concept freeze
Management approval of the preferred product concept, business direction, and feasibility basis.
Control plan
A production document defining controlled characteristics, checks, methods, frequency, ownership, records, and reaction plans.
COP
Conformity of Production: evidence that series-built vehicles continue to conform to the approved type.
DFMEA
Design Failure Mode and Effects Analysis, used to identify design risks and plan prevention or detection controls.
DV
Design Validation: testing that confirms the engineering design meets defined technical requirements.
DVP&R
Design Verification Plan and Report, the controlled record of requirements, tests, acceptance criteria, results, and status.

E–H​

ECU
Electronic Control Unit that monitors inputs, executes software logic, and controls vehicle functions.
EOL test
End-of-Line test performed near the end of production to verify functional, electrical, diagnostic, safety, or performance requirements.
EMC
Electromagnetic Compatibility: the ability of equipment to operate correctly without causing or suffering unacceptable electromagnetic interference.
EMI
Electromagnetic Interference that can disrupt electrical or electronic functions.
FTR
First Time Right: the share of units or processes completed correctly without repair, rework, or repeat activity.
Gate review
A formal evidence-based decision point used to approve, hold, redirect, or stop a development phase.
GD&T
Geometric Dimensioning and Tolerancing, a symbolic system for controlling part geometry and assembly function.
Homologation
The process of demonstrating compliance and obtaining regulatory approval for a vehicle or component in a target market.

I–P​

Industrialization
The conversion of an approved design into capable production processes, equipment, controls, suppliers, logistics, and trained operations.
KPI
Key Performance Indicator used to track quality, cost, delivery, safety, productivity, compliance, or customer outcomes.
MES
Manufacturing Execution System used to control, record, and trace production operations.
NVH
Noise, Vibration, and Harshness: the measurable and perceived refinement behavior of a vehicle.
OBD
On-Board Diagnostics used to monitor system performance, store faults, and support compliance and service.

Overall Equipment Effectiveness, commonly calculated from availability, performance, and quality.
OTA
Over-the-Air delivery of vehicle software, calibration, configuration, or related digital content.
PFMEA
Process Failure Mode and Effects Analysis used to identify manufacturing risks and define process controls.
Pilot build
A limited production-intent build used to validate the product, process, equipment, quality system, material flow, and workforce.
PPAP
Production Part Approval Process used to show that a supplier understands requirements and can repeatedly produce conforming parts.
PPM
Parts Per Million, a normalized measure often used to report defect or claim rates.
Pre-SOP
The final readiness phase before Start of Production, focused on stable processes, closed issues, and management approval.
