Explanation:

In business specialization refers to making one or very few products at a very high quality and selling them at a high price. Think of a company like Apple, they make very few products, phones, laptops, computers and accessories. Even in these products, the software, operating systems and processors are Apple's, almost every other part they buy from other companies. So they make sure to produce what they are good at and buy the rest from others, and since what they are so good at making what they make they can sustain this business model.
