The research presented in this paper is relevant to the disruption
management for supply chains that adopt the close/closed
supplier relationships in the sectors other than the automobile
manufacturing. The close/closed supplier relationships are often
used in manufacturing of the products that require high quality
and unique technology components such as machine tools, gas
turbines and airplane engines. For the key components in these
industries, a few qualified vendors exist and they work with their
buyers from its design stage on. For such a situation, the results of
this paper can be relevant.
In Section 3, the coordination mechanism of Toyota Production
System is constructed by summarizing the relevant elements from the
existing literature. As stated in Section 4, the case description in this
paper is based on the information and data that has appeared in the
publicly available sources, and has been cross-checked against the
Renesas Electronics’ press release documents. The development and
arguments in this paper are not based on the interviews with
personnel from either Renesas Electronics or Toyota. Therefore, they
do not reflect the views of either of the companies on the issues. The
results of the analysis in this paper have not been endorsed by the
companies, and the author is solely responsible for them.
