Toyota will need to make some aggressive changes here shortly or they just won't be able to compete.
They are making progress with innovation, but still have a lot of stagnation compared to the competition... The "Toyota way" worked for a while, but I know people that tried to apply the same principals in technology related industries (like microprocessor development) and it failed in catastrophic ways.
Hopefully, they can maintain quality while still keeping up with rapidly changing market and regulatory pressures.
