A Comparison of Just-in-Time and Batch Manufacturing: The Role of Performance Obstacles

Abstract

Employee perceptions of performance obstacles were measured during a conversion to “just-in-time” (JIT) manufacturing methods in which creation of manufacturing “cells” was the major focus of the change. Under the new system, employees perceived fewer problems with parts and work-related information than employees working in a batch system. However, the JIT system intensified several other perceived obstacles related to computer system use, training, scheduling, and reliance on co-workers. These results indicate that, contrary to general expectations, the effects of JIT on employees may not be all positive. The implication for managers is that they should give employee-related issues serious consideration during the implementation of such systems.
