Rio Bravo IV management team failed to analyse Japanese and Mexican markets, this is demonstrated by lack of proper planning and customer focus. It is also evident that language barrier was a problem. They went a step further to salvage the problem by partnering with Sumitomo Wiring, a company with a reputation for outstanding quality, and a major supplier to the Japanese auto industry. Packard Electric thought because they were the leaders in the US market, they could do the same internationally.
One of the problems was that none of the management team had the required experience for their managerial positions and hardly anyone spoke Spanish. Furthermore, the factory was poorly managed; hence, they could not deliver the requirements of New United Motor Manufacturing Industry (NUMMI).
