Six Sigma Tutorial >  Defect based Six Sigma Metrics

Six Sigma Engineering

• A Six Sigma Engineer develops efficient and cost effective processes to improve the quality and reduce the number of defects per million parts in a Manufacturing/Production environment.
• Six Sigma Engineers  determine and fine tune  manufacturing process. Once a process is improved, they go back and re-tune the process and reduce the defects. This cycle is continued till they reach 3.4 or less defects per million parts.
• Six Sigma is all about knowledge sharing. If a company has more than one manufacturing unit/plant, its more than likely that one of the plants produces better quality than others. The Six Sigma team should visit this higher quality plant and learn why its performing better than others and implement the techniques learned across all other units.
• Research/Design department within a company can use the above techniques to learn from another R&D departments in the same company or affiliate companies and implement those techniques.
• Motorola developed a five phase approach to the Six Sigma process called DMAIC.

DMAIC

• Define opportunities
• Measure performance
• Analyze opportunity
• Improve performance
• Control performance
