Define – Present Pain Areas

Short Term

Long Term

- Reduce defects ,delays and deviations .- Use data to focus on improvement efforts .- Evaluate and realign the work flow into production .- Ensure measuring tools accuracy .- CAP implementation in each production process to

introduce the zero defect concept .- Improve machine & its operators performance .

- Ensure Kanban for RFT manufacturing .- Reduce process constraints & errors .- Improve suppliers delivery lead time .- Reduction in export lead time - Increase cut to ship ratio.- Recognize , review and refocus efforts .- Stabilize and sustain the improvements .

Define Phase – Project Charter

Business Case

TEXEUROP (BD ) LTD impacted by huge

loss from 1st January 2015 to 30 June

2015 , USD $ 18,00000 accounted for 10%

defect which was higher than desired and

resulted a big challenge by delivering

defective product to retail stores in Europe

& USA .Where the sigma level counted 2.7

& Saving Target USD 200,400/-

Opportunity Statement

TEXEUROP (BD ) LTD started its

quality improvement journey with TUV

SUD , South Asia on April 2015 . TUV

SUD ‘s coach is providing guidance &

training to improve production process

by statistical tools & lean techniques. .

We confidence in to accomplish our

goal by 31st Dec.2015 .

Goal Statement

( By 31st December 2015 )

- Attain sigma level -3.000

DPMO - 66,800

Yield % - 93.32

Savings Target - USD 200,400

- 90 % reduction in Lead time .

- 90% reduction in all inventories .

- 100% increase in productivity.

- 50% reduction in process errors

Project Scope

The project scope covers all production

process of TEXEUROP ( BD ) LTD , its

products performance ,process input –

out put , suppliers , brands , retail

stores & all other stake holders .

New Process Performance Result

New Sigma Level 2.98 from 2.77 and total saving USD 2,00,090/-

( Saving came in Sep to December 2015 )

1. Pilot Line efficiency improved from baseline 39.% to 52% by 31st

December 2015 .

2. Pilot Line sewing cost produced as 865 taka from baseline per person

in 10 hours is 765 taka ( as per August by 31st December 2015 .

3. Pilot line Productivity finally reached 56 from baseline per person is

37.9 by 31st December 2015.

4. Factory cut to ship ratio increased .5% from baseline is 93.67

5. 10 Number of workers unskilled in sewing lines .

6. 05 Sewing method improved instead of 07.

7. 06 numbers of operators made as zero defect operators .

8. Root cause conducted on skip stitch , broken stitch , Oil , Stain needs

to be found out and actions should be taken .
