Tacit knowledge transfer and spillover learning in ramp-ups

Abstract

Purpose With shortening product life cycles and an increasing number of product variants, manufacturing firms perform more production ramp-ups. In this context, learning is crucially important to quickly achieve high production process quality and stability. The paper aims to discuss this issue. Design/methodology/approach Through a laboratory experiment, this study analyzes spillover learning between consecutive ramp-ups and how this phenomenon is influenced by tacit knowledge transfer through observation and imitation. Findings The results prove the existence of spillover learning between consecutive ramp-ups. Moreover, they provide evidence how tacit knowledge transfer through observation and imitation enhances learning of new tasks in consecutive production ramp-ups. Research limitations/implications Future research could focus on the specific psychological processes driving tacit knowledge transfer and spillover learning, a topic which is only touched upon in this paper. Practical implications The findings show that manufacturing firms should not only aim at reaching a steep learning curve during a single production ramp-up, but should also take into account the effects of spillover learning with regard to future production ramp-ups. Furthermore, the paper provides novel insights concerning the allocation of workers to production tasks with regard to previous experience when introducing new personnel and during ramp-up phases. Originality/value Previous evidence on the existence and characteristics of spillover learning in production ramp-up situations is not conclusive. This paper provides new and unambiguous insights by considering different organizational settings.
