Total Breakup of marks in Rating System (2500)

Total Rating Marks will be =2500

Breakup of total marks:- Monthly Basis (1000) + Annual Basis (1500)
Summary Table


Breakup of Monthly Rating System

Quality Rating + Delivery rating= 1000 Nos

  • Quality Rating marks:- 700 Nos
  • Delivery Rating marks:- 300 Nos

Breakup of Quality Rating marks (700 Marks)

Incoming Quality  + Warranty = 700 
  • Incoming Quality Marks = 350 marks
  • Warranty Marks = 350
Marks Calculation for incoming quality:- 
  1. Defect rating= 150 Marks
  2. QPCR =50 marks
  3. Line Rejection Rating= 100 marks
  4. Record  Management=  50 marks.

1. Defect rating:-

Defect Rating formula is:-150-( A* 75-F*30-G*10- R*25-)*K
  • A= Nos of A rank defects [Safety Defect]
  • F= Nos of functional defects
  • G= Nos of general Defects
  • R= Nos of repeated defects
  • K= Factor (Nos of defects/Total nos of active supplied parts)

2. QPCR rating:-

QPCR rating calculation formula:-50-( G* 50+R1*50+S*50+K*50)
  1. G*= QPCR (Quality problem Counter measure Report) raised for global audit
  2. R1=QPCR raised for receipt inspection
  3. S= QPCR raised for spare parts
  4. K= (Kadio) if QPCR is raised for parts supplied outside India

Note:- If QPCR raised then 50 marks will be reduced.

3. Line Rejection Rating :-

First we have to understand categories of line rejection. Line rejection rating marks are 100 Nos.
  • A-Design fault 
  • B- Wrong part supply by vendor
  • C-Damage during transportation
  • D- Damage due to improper packing
  • E-Parts without sample approval
  • F- Obsolete parts supplied by vendor
  • G =Rusted material supplied by vendor
  • H=Rework rejection
  • I = End NG
  • J= Blow hole
  • Q= Quality issue*
Line Rejection Rating Formula is (100 – PPM) as shown in below picture:-

in above formula you can see, its depend upon PPM, formula is 100-PPM. Defect parts is supplied to Customer in any defect category will be count in Q category for ppm calculation. Lets say you have not sent any defect part at customer end, so your PPM will be zero and line rejection rating will be 100-0=100.

4. Record Management Rating:-

Record management rating marks are 50. These marks are given on the basis of on time submission of documents at customer end. Marks are given in two factors:-

  • 4M change record- 25 marks
  • Monthly inspection report submission- 25 marks

All documents to be submit before decided target date, if you delayed, marks will be cut, if submit in first week of month then 25/25 marks for each factor, if you submit in 2nd week of month then 12.5/12.5 marks, if you submit in last of month then ZERO.

Breakup of Warranty Rating Marks (350)

Total marks for Warranty is 300. And marks are given into two factors.
  • Nos of claim- 175 marks [Nos of claims/10000—175]
  • Warranty Cost -175 marks [Warranty cost/Part supplied—–175]

Calculation for warranty marks:

8.75 marks deduced for every claims per 10000 parts supplied & 17.5 points to be deduced for every claim of 10 paisa per part supplied. You can understand by below picture:-

Breakup of Delivery Rating marks (300)

Total marks for Delivery is 300. Monthly rating for delivery is divided into 3 factors:-
  1. Quantity Default –75 marks
  2. Time Default—–150 marks
  3. Spare Default——75 marks
1. Quantity default:- 75 marks 

QD= 75- (n*18.75*100);  Here [n= % of qty default in N months]

%QD= No of Nagare Default/ Total Number of E nagare Count

Note:- If %QD>0.03% then marks will be Zero.
2. Time Default- 150 marks

T.D= 150-(n*1.5*10); Here [n= % of  time default in N months]

%TD = Total No of time default (>2 hours)/Total E-Nagare

Note:- if %TD is more than 7.5% the marks will be ZERO.

3. Spares Default

S.D= 75- (n*3.75); [n= % of  spare default in N months]
Note:- if %SD is more than 15% the marks will be ZERO.
