Effectiveness of each inspector
In finding the effectiveness of each of the inspector there are various steps which will be involved. It will involve computing the number of times which the inspectors’ assessments agree. The effectiveness of each of the inspector will represent the percentage of time when all the inspectors agree and when their agreement matches with the standard. The desired results for each of the inspector’s effectiveness is 100% but 90% is adequate (Chieh, 2012). The table shows the observations for Inspector A, inspector B and the master/expert.

For the inspector A 13 out of the 19 samples were similar whereas for inspector B 13 out of the 19 samples were similar and hence the effective rate for inspector A & B are 89.5% and 68.4% as computed in the above table. Thus, additional training is required by both the operators and this is because they are both not consistent with their own work. Inspector B is more inconsistent and this might be more because of the level of training and not a gap in the standardized procedure or an issue with the equipment (Chieh, 2012). If the effective rate for the two inspectors was the same then it would cause suspicion that the inconsistencies were because of an external factor.
