IMPLEMENTATION OF LEAN SIX
SIGMA IN MANUFACTURING
PROCESS
Karan Bhagat – 17BM60042
INTRODUCTION
•
This six sigma project aims to improve the manufacturing of a semiconductor company which was focused on
manufacturing circuit cartridge for inkjet printers
•
One of the major issues was that the circuits were tested in the final stage for any defects in order to approve or reject
them
•
The six sigma methodology is focused on continuous improvement which minimizes defects and variation towards an
achievement of 3.4 defects per million opportunities
•
Once a project or goal is defined, the organization follows the disciplined six sigma process that’s defined by five
phases:
1. Define – in this step the problem statement is defined and all the parameters are listed
2. Measure - measure existing systems to learn what can be considered a baseline or benchmark, among other things.
3. Analyse - identify ways to eliminate defects. This can be done in a variety of ways, including statistical analysis to
determine the root cause of an issue.
4. Improve - seek optimal solutions, then develop and test the plan of action for improving a process or goal.
5. Control - The Control step can be ongoing—an organization may modify operating instructions, policies, or procedures
to help prevent future defects.
CONCLUSION
•
The implementation of this project has been considered as successful because the critical factor
for the process were found and controlled
•
The base line of the project was 3.35 sigma level and the gain 0.37 sigma that represents the
elimination of 1.88% of nonconforming units or 18,788 ppm’s
•
Also, the maintenance preventive program was modified to achieve the goal stated at the
beginning of the project.
•
It is important to mention that the organization management was very supportive and
encouraging with the project team.
•
Finally, six sigma implementation can be helpful in reducing the nonconforming units or
improving the organization quality and personal development.
