Diversified Technologies Ltd. (DTL) makes four types of products, each type to be sold to different types of clients. For example, one product is sold exclusively to automobile repair shops, whereas another is used mainly in hospitals. Customer expectations and needs are surprisingly similar throughout the world. The company has separate marketing, product design, and manufacturing facilities in Asia, North America, Europe, and South America because, until recently, each jurisdiction had unique regulations governing the production and sales of these products. However, several governments have begun the process of deregulating the products that DTL designs and manufactures, and trade agreements have opened several markets to foreign-made products. Which form of departmentalization might be best for DTL if deregulation and trade agreements occur?
