I found this question on Oliver F. Lehmann prep test (200 questions document):

136. You are running a project to develop the production process for a future electronic component. Evaluating some first test batches, you found out that the precision is generally very good, but that you have some irregular outliers in a completely unpredictable pattern. What should you do?
o Ignore the outliers; they are not relevant as long as the yield from the production is sufficiently high.
o Try to increase the accuracy of the process by adjustments, thus reducing the number of outliers.
o Inform the designated production manager of your observations and ask him to take care after handover.
o Research outliers, they may give you important insights into problems which may trouble later production.

Correct answer is (D), and I don't completely understand why answer (B ) wouldn't be correct too. Would like to know your thoughts.

Hi Julia,

In some exam questions, there may be multiple correct answer, it is in your best interest to pick the best answer out.

I agree that answer B is also correct, however it is better to investigate what caused the outliers first before taking actions
