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$?$

a$.$ Ignore the outliers; they are not relevant as long as the yield from the production is sufficiently high.

b$.$ Try to increase the accuracy of the process by adjustments, thus reducing the number of outliers.

c$.$ Inform the designated production manager of your observations and ask him to take care after handover.

d$.$ Research outliers, they may give you important insights into problems which may trouble later production.
