Here is a very good story about Toyota, it’s supply chain and managing its risks, from the February 25, 2010, issue of The Economist.
In light of its recent troubles I am not really troubled by Toyota. Perhaps I should be, but I am not. I have a Toyota and would likely buy another one before I even look at GM, Ford or Chrysler. Of course Toyota made some mistakes – but I know enough about Lean Six Sigma to know that defects will happen.
So while Toyota’s grades have fallen from A+ to A- or B+, I still perceive the US Big 3 as having grades of D+.
