Tolerance requirement general theory: pilot study results analysis

The paper concentrates on the analysis of data from the first of two experiments designed to examine aspects of tolerance requirement general theory. Both experiments were designed to constitute a pilot study into a possible relationship between difficulty of a task and time taken to carry it out. The objectives were to identify and eliminate any spurious relationships within the data, and to establish the form, if any, of a robust mathematical relationship between one aspect of the work activity and time taken. The aspect focused on is that of tolerance requirements, which are not seen in the context of this research as being optimum plus‐or‐minus values for tolerance sizes. Data analysis results in a re‐examination of the proposed nature of tolerance requirements. This leads to further development of tolerance requirement general theory, particularly with regard to the calculation of tolerance requirement values.
