Computer-aided design also is not automatic programming, although automatic programming techniques must necessarily play an important role in compute… - Douglas T. Ross

This report summarizes the activities of the M.I.T. Computer-Aided Design (CAD) Project from 1 December 1959 through 3 May 1967 in the development of a generalized 'system of software systems' for generating specialized problem-solving systems using high-level language techniques and advanced computer graphics. Known as the AED Approach (for Automated Engineering Design) the Project results are applicable not only to mechanical design, as an extension of earlier development of the APT System for numerical control, but to arbitrary scientific, engineering, management, and production systems as well.

The assertion that a problem unstated is a problem unsolved seem to have escaped many builders... All too often, design and implementation begins before the real needs and system functions are fully known. The results are skyrocketing costs, missed scheduled, waste and duplication, disgruntled users and endless series of patches and repairs euphemistically called "systems maintenance"

There are certain basic, known principles about how people's minds go about the business of understanding, and communicating understanding by means of language, which have been known and used for many centuries. No matter how these principles are addressed, they always end up with hierarchic decomposition as being the heart of good storytelling. Perhaps the most relevant formulation is the familiar: "Tell 'em whatcha gonna tell'em. Tell 'em. Tell 'em whatcha told 'em." This is a pattern of communication almost as universal and well-entrenched as Newton's laws of motion.
