U. S. appliance manufacturers find that different customs about shopping must be considered to determine product design. For instance, people in Northern Europe shop only once a week, so they need bigger refrigerators than Southern Europeans who shop daily. Furthermore, Northern Europeans insist that freezers should be on the top just as loudly as Southern Europeans insist that freezers should be on the bottom. Other regions use their appliances differently and have other different product demands. Given this information, you should conclude U. S. appliance manufacturers are likely to be more successful if they used a(n) marketing strategy.
