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 .

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 –
