If the probability of a unit being conforming or nonconforming, depends on the previous unit being conforming or nonconforming, can p-chart be applied on the process?

If the probability of a unit being conforming or nonconforming, depends on the previous unit being conforming or nonconforming, can p-chart be applied on the process? Correct Answer No

In processes where nonconforming units are clustered, i.e. the probability of one unit to be conforming or nonconforming depends on the previous unit being defective or not, p-chart can’t be applied to them, as p-charts are designed on the basis of binomial probability or independent trials.
