Customization refers in the context of international marketing to a country-tailored product strategy which focuses on cross-border differences in the needs and wants of target customers, appropriately changing products in order for them to match local market conditions. Therein, customization follows a market-driven orientation (as opposed to a product-driven orientation) and aims at increasing customer satisfaction by adapting the company's products to local needs.
CUSTOMERization means identifying and serving what you perceive as your optimal customers. CUSTOMERization - Targeting Optimal Customers, R Craig Palubiak, 1998
