"If our testing does not find any bugs, then our software doesn't have any bugs."
I am trying to reconstruct what is going on at Toyota.
Toyota management is telling the world what is in the above quoted sentence. There is a good chance they believe what they are saying.
Are they hearing this from engineering. If so they are hearing it from the incompetent engineers. Are these engineers merely courtiers? Are they just telling management what they want to hear. Is management not listening to the engineers who have a clue?
Inquiring minds want to know.
