ABSTRACT
Man-made systems come into being through a process that will be referred to in this book as system development, a process for solving a complex problem initially framed in a customer need statement verbally presented or in writing uttered or stated by someone who concludes, “There is something I must do that I cannot do with what I have.” The system development process may be applied to a new, unprecedented problem never before solved resulting in a clean-sheet-of-paper development but can also be applied to major modications or reengineering of existing systems. The system development process is accomplished by programs organized, staffed, and run by enterprises for organizations often called acquisition agents to be used by organizations often called users.
