Design for six sigma most commonly uses which of the following tools?

Answer options

• A. 5 whys
• B. Root cause analysis
• C. Process decision program chart

Correct answer: B

Explanation

The correct answer is B, Root cause analysis, as it is essential for identifying the fundamental reasons for defects and issues in a process.
