The impact of Shukko (employee transfers) within group companies on the capability and speed of promotion of engineers

This study examined the impact of Shukko (employee transfer) experience of research and development (R&D) engineers in a Japanese automotive manufacturing group on their capability improvement and speed of promotion. It found that internal/external capabilities improve with the length of the service, and that internal/external capabilities improve with Shukko (employee transfer) experience and that Shukko and external capability do not have a significantly positive impact on the speed of promotion, and instead the level of internal capability is necessary for the speed of promotion.
