A quality characteristic has a specification (in cm) of 0.40 ± 0.03. If the value of the quality characteristic exceeds 0.40 by the tolerance of 0.030 on either side, the product will require a $180.00 repair. In the given scenario, the Taguchi loss function is correctly represented by which of the following equations?
Selected Answer: a.
L(x) = 200,000 (x − 0.40) 2
Correct Answer: a.
L(x) = 200,000 (x − 0.40) 2
Response Feedback: Rationale:
Correct. In the given scenario, the Taguchi loss function is correctly represented by the equation L(x) = 200,000 (x − 0.40) 2. The loss associated with a deviation of (x - T) = 0.03 from the target is L(x) = $180, where T is the target nominal value (0.40) and x is the actual value of the dimension (0.43 or 0.37). To find the loss function for any value of x, these values are substituted into equation L(x) = k(x - T) 2, which is solved for k:
180=k(.03) 2
k=180/.0009=200,000
and thus the loss function is
L(x) = 200,000 (x – 0.40) 2

empowerment.
Response Feedback: Rationale:
Correct. David's employees being allowed to spend up to $200 to resolve customer complaints is an example of empowerment.
