SH2.2 (a, b)If we are focusing on quality improvement, we would want to determine the categories which a responsible for the highest proportion of errors. Thus, a Pareto diagram would be most appropriate.

(c)Almost half the errors are accounted for by copy error, typesetting, and wrong position. If we also include ran-in error and velox, almost two-third of the errors are included. We would suggest that reduction of these errors be focused upon if our goal is improvement in the number of errors committed.

SH 2.3 The information in Table SH2.1 represents only the frequency of the different types of errors, and does not indicate the importance of each error. Thus, it would be useful to obtain information about the cost of each type of error.

(b)If we are focusing on quality improvement, we would want to determine the categories which are responsible for the highest amount of errors. Thus, a Pareto diagram would be most appropriate. (c) The category that is causing the largest amount of errors is ran-in error. The five most important categories ran-in error, wrong position, paste-up, wrong ad, and typesetting account for almost two-thirds of the total amount of errors.

SH2.6 We would recommend that the causes for the various types of errors be determined. Once this was done, each type of error listed could be stratified into a further set of errors.
