Uwe Mierisch on Building Hardware

I can confirm what you write also from my experience. In the automotive industry we need to be very focused on quality, because failures can cost lives. Even small ones. In my carrier I had to deal with those issues constantly and we used exactly the methods you explained. There is only one thing I see differently. Firing people does not create a quality oriented culture. Quite the opposite, it creates a culture of fear and bad politics and this is not helpful at all. If managers set quality on priority no one consistently (also when in their own decisions), encourage speak up, care and take ownership, when they are needed, quality will emerge.
