ABSTRACT

Conceptually, a system block is made up of a system (striped elements in Figure 3.2), one or more end products (black elements), two or more subsystems for each end product (gray elements), and the ensemble of enabling products (white elements). Each end product and each enabling product includes one or more of the following: Hardware, software, Žrmware, personnel, facilities,

data, materials, services, and processes. As a system is developed into end products, enabling products, and systems and subsystems, the complete range of technical processes discussed in Chapter 4 is applied to each of them. ese technical processes are also recursive in that they are applied to each system block and elements of the system.
