Explanation / Answer

P outlines are utilized to screen the extent of nonconforming units of a process on a sample of tests taken from the process at given circumstances (hours, shifts, days, weeks, months, and so on.). Initially, the tests are performed to determine the proportion of nonconforming customers. After that, a sample is taken to estimate if there are some customers who have visited again for the maintenance.
