PPAP / APQP Basic Knowledge (Easy Explanation)
1. APQP क्या है?
APQP :-
Full Form: Advanced Product Quality Planning
APQP एक planning system है जिसका उपयोग नई product development में किया जाता है ताकि:
Quality अच्छी रहे
Customer requirement पूरी हो
Production smoothly चले
Defect कम हो
यह mainly automotive industries में use होता है जैसे:
Maruti Suzuki
Tata Motors
Mahindra & Mahindra
APQP के 5 Phases
Phase 1: Plan and Define Program
Customer requirement समझना
Risk identify करना
Target set करना
Example:
Part dimension
Material
Safety requirement
Phase 2: Product Design & Development
Drawing preparation
DFMEA
Design review
DFMEA = Design Failure Mode Effect Analysis Design में possible failure खोजते हैं।
Phase 3: Process Design & Development
Process Flow Chart
PFMEA
Control Plan
Work Instruction
PFMEA = Process Failure Mode Effect Analysis
Process में कौन-सी problem आ सकती है यह analyze करते हैं।
Phase 4: Product & Process Validation
Trial production
Measurement checking
Capability study
PPAP submission
यहीं पर PPAP आता है।
Phase 5: Feedback & Corrective Action
Customer complaint analysis
Rejection reduction
Continuous improvement
2. PPAP क्या है?
PPAP
Full Form: Production Part Approval Process
PPAP एक process है जिसमें supplier customer को proof देता है कि:
Product drawing के अनुसार बना है
Process stable है
Mass production possible है
Simple language:
“Customer को विश्वास दिलाना कि हमारा production process सही है।”
PPAP कब किया जाता है?
New product launch
Drawing change
Material change
Machine change
Supplier change
Process change

Final PPAP approval
PSW क्या है?
PSW
PSW = Part Submission Warrant
यह final approval document होता है।
Customer sign करके approve करता है कि:
Part acceptable है
Production start हो सकता है

Manufacturing Line Example
Suppose नया brake part develop हुआ:
Customer drawing देता है
APQP team planning करती है
Trial production होता है
Dimension check होता है
PPAP file बनती है
Customer approval देता है
Mass production start होता है
Short Memory Trick
APQP
“Planning before production”
PPAP
“Customer approval before mass production”
