Process-Oriented Design

1. Introduction

Structured design is the art of designing system components and the interrelationships between those components in the best possible way to solve some well specified problem. The main goal of design is to map the functional requirements of the application to a hardware and software environment. The results of structured design are programming specifications and plans for testing, conversion, training, and installation. In addition, the design may result in proto typing part or all of the application. This section discusses the mapping process and the development of program specifications. The other topics are discussed in Chapter 14. 

The goals of structured design, as first documented by Yourdon and Constantine [1979], have not changed much over the years. They are to minimize cost of development and maintenance. We can minimize the cost of development by keeping parts manageably small and separately solvable. We can minimize the cost of maintenance by keeping parts manageably small and separately correctable. In design we determine the smallest solvable parts as a way of managing application complexity.
