The links between lean manufacturing practices and concurrent engineering method of new product development : An empirical study

Purpose – The purpose of this paper is to demonstrate the relationships between lean manufacturing (LM) principles and concurrent engineering approach to new product development (CENPD). Design/methodology/approach – A survey instrument based on a number of critical factors was used to examine if there are relationships between LM and CENPD. In addition to general organization and managerial profile items, the survey contained 44 items (22 paired) regarding similarities between LM and CENPD factors. Also, the survey instrument contained a number of questionnaire items on NPD performances for LM companies using CENPD and conventional companies. Findings – Statistical results show high degree of similarities between LM and CENPD factors. The results also indicate that LM organizations are able to develop new products with 63 per cent better quality, 52 per cent less development time, 45 per cent less development cost, and 36 per cent less manufacturing cost than conventional companies. Research limitations/implications – Research is not industry specific. Future research needs to focus on specific industries. Practical implications – LM companies are able to develop new products better, faster, more often, with less development cost, and less manufacturing cost than conventional companies. Originality/value – The benefits of LM principles go much beyond inventory reduction and frequent deliveries. These principles are also applicable to other areas such as NPD.
