The People Dimension In Logistics And Supply Chain Management – Its Role And Importance, Edward Sweeney May 2013

The People Dimension In Logistics And Supply Chain Management – Its Role And Importance, Edward Sweeney

Books/Book chapters

It is widely recognised that the effective application of logistics and supply chain management (SCM) has a vital role to play in European economic recovery. Experience suggests that success in achieving higher levels of supply chain integration (SCI) depends on both physical and technical components (the hard-wiring), as well as human and behavioural components (the soft-wiring). There is significant evidence that the latter has been largely neglected by the logistics and SCM community. Furthermore, it appears that the majority of supply chain improvement initiatives by practitioners have been primarily concerned with technological, structural and process issues. This chapter …
