Success factors for continuous supply chain process improvement: evidence from Japanese manufacturers

This study explores how firms can realise ‘continuous’ supply chain process improvement. Specifically, this study proposes the success factors of routinised activities (also called ‘repeated activities’) in the supply chain process improvement. Eight Japanese manufacturers are selected for the case studies. These firms are selected based on their supply chain process operation capabilities. From the case studies, we find that the planning of supply chain process improvement depends on the existing stage of the firm’s Supply Chain Management reform. In addition, even firms with high scores for supply chain process operation capabilities do not have supply chain performance systems. Furthermore, quite surprisingly, many Japanese manufacturers tend to improve their supply chain processes in the absence of such systems.     

Supply chain management maturity and performance in SMEs

Supply chain maturity models attempt to disseminate best practices in supply chain management (SCM). One basic idea behind these models is that increased maturity will lead to improved supply chain performance, which in turn will lead to improved financial performance. There is, however, little empirical evidence about the relationship between supply chain (SC) maturity and financial performance, specifically in SMEs. The results of this study indicate that there is a strong relationship between SCM maturity and SC performance in SMEs, as well as some relationships between SCM maturity and financial performance. One conclusion is that if firms use maturity indicators in the Supply Chain Operations Reference areas to improve their processes, they will most likely achieve positive effects on supply chain performance and probably also on financial performance.     

Supply chain management executives in corporate upper echelons

Supply chain strategies and their implementation have been recognized as a source of competitive advantage. According to the principle “structure follows strategy”, we expect the number of firms having supply chain management (SCM) functions represented on their top management team (TMT) to have increased in the past years. However, little is known about the degree to which executives responsible for SCM functions (i.e., Chief Supply Chain Officers) are present or absent in TMTs and if their presence is related to firm performance. Therefore, we study the TMTs of large US corporations and show that SCM is present in upper echelons, either through executives whose responsibilities explicitly include SCM or indirectly by executives, especially CEOs, who had acquired SCM experience in their previous positions. However, firms׳ operating margins are lower when a Chief Supply Chain Officer is present in the TMT.
