It helps managers see what’s going on in the operation from a bird’s eye view, without conducting a detailed time study. Work sampling uses numerous observations taken at random times throughout the work day over the course of a long period of time to determine the amount of time spent on various activities in the workplace. As seen in the lab, 400 random observations were taken in total over the course of ten days to predict the actual time spent in production time, necessary delays, and unnecessary delays. According to these results, 68.75% of the time was spent in production time, 15.25% of the time was spent in necessary delays, and 16% of the time was spent on unnecessary delays. From this data, one can conclude that the percent of time spent on unnecessary delays is too high and further investigation should be taken into account to t ry to reduce this time. Like all data collected, these values may not be the true percentages spent on these tasks. Chance plays a big part in the uncertainty of this data, but with larger these tasks....
