You should notice the difference between foreign and domestic market and set your target according to specific situation of foreign market. For example: given the different state of living standard the purchasing power of your target market may be higher or lower than the domestic market. If you ignore the difference you are likely to make mistakes in products’ pricing in foreign market.
You should ensure that your research team is excellent at carrying out research in a foreign country. That means every member of the team should mater the native language and be familiar with the specific culture of the target market.
