Unless the company owner is ready to invest more money in employee training, build fewer units for the time needed to retrain and change the company culture, spend the money on real marketing to learn what their customers want in each price range and model type, and the owner wants to change their focus from margins to quality the new vp of quality is not going to have much impact on product quality.
The desired changes must come from the top down, starting with the owner. Simply hiring a new vp does not mean the owner is prepared to change their attitude.
Plus the owner must be willing to push back on impatient customers when defects are found and the corrective action delays delivery.
