A new improved model is introduced for the performance of inspectors of user requirements documents. The model, which is based on a linearity assumption employs only two non-dimensional metrics in the [0;1] interval. They characterise the error detection ability of the inspectors and their domain knowledge level. It is our experience that one learns to reason with these two metrics. The applica...

The character of cracks is an important parameter in manufacturing of test pieces for UT qualification. In these studies we (Trueflaw and Fortum Nuclear Services) have manufactured 22 cracks by different production methods. Opening of cracks have been manipulated for different values. Sizing of the true dimensions of cracks has been made by destructive tests. These values are the basis for the ...

A cognitive work analysis of quality inspection in the optical industry has been carried out in order to devise a training programme. The task concerned the inspection of high quality human eyeglass lenses. We conducted an experimental investigation of defect detection and acceptability decision-making tasks in 18 experts and novice inspectors. Detection and decision-making were investigated to...
