A Six Sigma engineer

Using Six Sigma
concepts, 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
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.
