determine which inputs have the greatest impact on the output value youre looking for
reduce variance in all processes in an effort to eliminate defects

Explanation:

Six Sigma aims to reduce process variance to eliminate defects. DMAIC (Define, Measure, Analyze, Improve, Control) is its core methodology. Identifying key input - output relationships is part of its analytical approach. Sustainable development/innovation and capturing industry voice are not central.

Answer:

• Determine which inputs have the greatest impact on the output value you're looking for
• Reduce variance in all processes in an effort to eliminate defects
• Implement the DMAIC methodology
