Some Methods of Evaluating the Productivity of Labor in Milk Plant Operations¹

Departments of Animal Industry and Experimental Statistics, North Carolina State College, Raleigh

ABSTRACT

A significant difference was found between plants in employee efficiency as related to the job performed by a worker. The per cent efficiency was calculated by dividing the number of productive observations by the total observations.

A significant difference was found between plants in functional efficiency, which is determined by dividing the theoretical time as established by standard times by the actual time consumed in the completion of the function.

Analysis of labor utilization by man-minutes required per 100 lb. and per package for the receiving, processing-packaging, and packaging operations in the plants included in this study indicated that a significant difference existed between plants.

No single efficiency determination alone can be taken as a measure of the relative efficiency of fluid milk plants. It is believed that the best evaluations can be reached by using the information provided by employee efficiency, function efficiency, and man-minutes per package and per 100 lb.
