Daniel, a Six Sigma Master Black Belt, is leading a project to reduce defects in the production of a specific component. After analyzing the process data, he identifies three potential root causes for defects. These root causes are not directly observable but can be traced back to design specifications, supplier variations, and operator training. What approach should Daniel take to prioritize and address these root causes effectively? Question 8 options: Daniel should prioritize the root causes based on their potential impact and ease of implementation, and address them one by one Daniel should disregard the root causes and look for quick fixes to reduce defects in the short term Daniel should consult with an external expert to make the final decision on which root cause to address first Daniel should focus on operator training as the primary root cause and initiate training programs to reduce defects Daniel should address all three root causes simultaneously to ensure a comprehensive improvement of the process
