Data Accuracy & Integrity

Consider the following situation:

A study is being carried about by a white goods manufacturer. Each worker on the assembly line is instructed to keep records on the time taken to assemble each component. The results of the study are intended to pinpoint bottle necks in the manufacturing process.

The results are compiled and as a consequence, various recommendations are made to management. Management disagrees with many of the recommendations and doubts the accuracy of the data used. It is later found that the the times by many of the individual workers were inaccurate: when the times are totalled, the result is greater than the hours each worker is present in the factory.

Discuss reasons why the workers recorded inaccurate times. Propose techniques to improve the accuracy of the data collected.
