“…Knowing this and the costs and values of decision outcomes, it is possible to derive the optimum fixed time so as to minimize total inspection costs (Morawski, 1978;Tsao, Drury, and Morawski, 1979).…”

Predicting Search Performance for Multiple Targets

1980

Performance in a visual search task is usually measured by the cumulative probability of locating a target, F(t), in a given time (t). Two extreme F(t) against (t) relationships have been postulated, one assuming that search is random, and the other assuming that search is systematic. However, these relationships have only been available {or the situation in which each search field contains a single occurrence of a single type of target. This paper extends both search models (random and systematic) first to the case o{ multiple occurrences o{ a single fault type within a search {ield and second to the case of multiple (ault types. For systematic search, these two cases can be combined to predict the effects of multiple occurrences o{ multiple fault types. The general F(t) relationships are given in each case and illustrated with a worked example.

“…This followed with more than three decades of research from the industrial inspection community (summarized in detail by Fox, 1973;Wiener, 1975, Drury, 1982, and See, 2012, with some of it focused on vigilance theory (e.g. Elliott, 1960;McGrath and Harabedian, 1961;Mackie, 1964;Baddeley andColquhoun, 1969, Tsao, Drury, andMorawski, 1979;Tsao and Wang, 1984;Murray and Caldwell, 1996) that stemmed from the pioneering work of Mackworth (1950). These studies were paralleled by researchers who began to understand the underlying models of human information processing that would become useful to JPA developers (Gagne, 1962;Kibler, 1965;Harris, 1969, Norman, 1981Rasmussen, 1982;Norman, 1983;Rasmussen and Vicente, 1989;Reason, 1990;Barshi and Healy, 1993;Allen and Rankin, 1997).…”

“…If a similar experiment equally spaced the faults (possibly by elapsed time) throughout the assembly task, then perhaps a vigilance decrement could be studied in a number of ways. It was mentioned previously that fault #12 was designed to address findings by Tsao, Drury, and Morawski (1979) and a later study by Tsao and Wang (1984) examined faults of different difficulty, suggesting that these faults may have different probabilities of detection. These and other vigilance studies may benefit from the recognition of different probabilities of detection for different types of error, both within and outside of the concurrent dual verification construct.…”

The Effect of Job Performance Aids on Quality Assurance

Job performance aids (JPAs) have been studied in a variety of disciplines and for many different types of tasks, yet this is the first known research experiment using JPAs in the quality assurance (QA) context. The objective was to assess whether a JPA has an effect on the performance of a QA observer in the concurrent dual verification construct using a simple checklist for a basic assembly task. Results show that the JPA has only a limited effect, however there were three significant findings that may draw interest from a variety of practitioners. First, a novel testing methodology sensitive enough to measure the effects of a JPA on performance was created. Second, the discovery that there are different probabilities of detection for different types of error and their impact on the QA context may be the most far-reaching result. Third, these results highlight the limitations of concurrent dual verification as a control against defects.

“…Tsao, Drury and Morawski [28] and Karwan, Morawski and Drury [29] found systematic search was more effective than random search. Many researchers [30,31,32,33] discovered that performance feedback, consisting of feedback on inspection errors, inspection time, etc., improved inspection performance.…”
