Application of Lean Production Case Study from Garment Sector of Pakistan 28 March, 2011

1. SMEDA-Industry Support Program Application of Lean Production Case Study from Garment Sector of Pakistan 28 March, 2011 Presenters: Mr. Haider Sagheer Mr. Qasar Wasique Ahmed Dr. Nabeel Amin `

2. Background of the Project • Labor intensive • Huge variety of products with small quantity orders • Inefficient production systems • High need of flexibility • Large employment Opportunities and increased share in export market

3. Evaluation Phase • House Keeping • Factory Current Efficiency Level • Factory Current Defect Rate • Material Handling • Space Utilization • Style Change Over Analysis

4. 1- House Keeping-before

5. House Keeping-before

6. House Keeping-before

7. 2. Factory Efficiency Following were the major steps taken for calculating factory current efficiency level: • SAM Calculation of major products • Calculation of Over time • Data Collection from Bundle induction to sewing lines • Data Collection of finished Bundles • Idle Time Calculations

8. 2. Factory Efficiency 22%

9. 3. Defect Rate • Data collection by introducing appropriate format's. • Data collection at end line and finishing stage. • Appointed end line checkers. • After collection of data for one month an average of 35-40% defect rate was observed.

10. Inspection Sheet Finishing

11. 4. Material Flow Analysis 840 Ft

12. Target Setting Phase Following Key Performance Indicators were defined as project target metrics: 1. Efficiency 2. Defect Rate 3. Material Handling 4. Space Utilization 5. Throughput Time 6. Cost/Pc

13. Implementation Phase • Implementing 5S/Visual Control Systems across the Factory • Implementation of IE functions • Conducting Style Change Over Analysis by SMED (Reducing throughput time) • Running of Sewing Line at target efficiency level • Implementing Hourly Based Quality Monitoring System • Implementing SQC techniques • Introducing Incentive System for Quality Control

21. Style Change Analysis (Model Line) Bundle Size: 15, Style: Short Date:13/5/10, Time: 10:30

22. Activities to introduce Flexible Production Line • Reduction of Bundle Size • Hourly Basis Monitoring System • Advance Cutting in Shelves • Implementation of Checklist for Accessories • Layout – Shifting of Special Machines • Selection Criteria of Operators, Payments, Disciplinary Issues,

23. Improved Material flow 328 Ft

24. Overhead cost Comparison (for 17 no of machines for one month) OH cost Difference per piece = 18-12.31 = 5.47 OH Cost Savings = 5.47*8125 = Rs. 44, 443

25. Quality Control System • Introduced Hourly Basis Reports End Line Finishing • Check Sheets – Major Defects ISSUES: Reports could not be properly filled due to large buddle size Operators were not submitting small bundles on time Low DHU is Key Factor for running model line, therefore immediate action must be taken to properly fill the Q.C Reports

26. Introducing Incentive System

27. Defect Rate DR reduces Upto 5%

28. Cost Savings Through Defect Rate Reduction • Avg. Production per Month = 60, 000 Pcs • DR Before =30%, Rework in Nos = 18000 pcs • DR After = 5%, Rework in Nos = 3000 pcs • Rework Difference = 18000 – 3000 = 15000 pcs • Avg. Operation Time =0.5 min • Total time = 15000*0.5=7500 min • Total time consumed in RW is 7* times of the operation 1st time performed. • Total time saved= 7500 * 7 = 52500 min • Avg. SAM per pc = 12 min *According to KSA study this factor ranges from 7 to 14 times of the operation 1st time performed.

29. Cost Savings Through Defect Rate Reduction • No. of pcs that can be produced = 52500/12*32 = 1400pcs • Avg. Profit per pc @15% (FOB=Rs.425) = Rs. 64 • Cost saving in RW/mth@15% per Mth = 1400 * 64 = Rs. 89,600 • Projected saving by sustaining the RW @5%over one year= 89,600*12 = Rs. 10,75,200

30. Cost Savings Through Defect Rate Reduction (Inspection Cost) • Salary per month(25 working days) = Rs. 7000 • Per day income (salary)=7000/25 = Rs. 280 • Avg. pcs inspected per day per Inspector=250 • No of days needed by one inspector=15000/250=60 days • Savings/Month By Reducing Inspection = 60*280 = Rs. 16800 • Projected Saving over one year through Inspection = 16800*12= 201,600

31. Total Savings Per Month Cost Savings by Reducing DR/month + Cost Savings By Reducing Inspection = Rs. 89600 + Rs. 16800 = Rs. 106400
