The Ishikawa diagram determines the causes which affect output y = f (x). Which of the following is NOT explained by the equation y = f (x)?
  1. The process sigma level.
  2. Causes for failures in the process.
  3. The inputs x which result in the output y.
  4. The combined effects of problems.
Explanation
Answer: A - The Ishikawa diagram allows lean practitioners to determine the causes which affect output y = f (x). The equation y = f (x) allows them to determine causes for failures in the processes, the inputs x which result in the output y, and the combined effects of problems. This equation is not used to determine the corresponding sigma level.
