Refer to Exercise 12.8.
Suppose that clerical error—either Thayne’s or the supplier’s—is the common root cause of the non-value-added activities. For each non-value-added activity, ask a series of “why” questions that identify clerical error as the activity’s root cause.
1: Why are we resolving discrepancies?
2: Why are documents being compared?
3: Why would the documents not agree?
4: Why would a document be wrong?
5: Why are the amounts different?
6: How can we avoid clerical error?
