Paraphrasing (16th paragraph)

Text

When IBM made this decision, computers were highly integrated products produced in an industry that was essentially vertical. An IBM computer con5isted of specialized components that could not be used in any competing product. The design, production, delivery and after-sales support of components, as well as the assembly of the final product, all took place in premises owned and managed by IBM. Other market leaders in the computer industry, such as DEC and Unisys, had similar structures.

The main idea of the paragraph

When IBM, who operates in much the same way as market leaders like DEC and Unisys, made its outsourcing decision, computers were highly integrated products produced in an industry that was essentially vertical.

IBM和DEC以及Unisys这样的市场领先者的运营方式大致相同,当它做出外包决定时,计算机在本质上垂直整合的行业内是属于高度集成的产品。
