“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 is a rigorous science, just waiting to be recognized and developed, which encompasses the whole of 'the software problem,' as defined, including the hardware, software, languages, devices, logic, data, knowledge, users, users, and effectiveness, etc. for end-users, providers, enablers, commissioners, and sponsors, alike.”

“From the computer application point of view the primary problem [of Computer-Aided Design] is not how to solve problems, but how to state them.”

“It is very difficult to define what is meant by computer-aided design since the complete definition is, in fact, the sum and substance of the total project effort which has only begun. It is much easier to describe, what is not computer-aided design as we mean it.”

“Computer-aided design is not automatic design, although it must include many automatic design features. By automatic design we mean design procedures which are capable of being completely specified in a form which a computer can execute without human intervention.”

“Computer-aided design also is not automatic programming, although automatic programming techniques must necessarily play an important role in computer-aided design.”

“Automatic design has the computer do too much and the human do too little, whereas automatic programming has the human do too much and the computer do too little. Both techniques are important, but are not representative for what we wish to mean by computer-aided design.”

“(SA) combines blueprint-like graphic language with the nouns and verbs of any other language to provide a hierarchic, top-down, gradual exposition of detail in the form of an SA model. The things and happenings of a subject are expressed in a data decomposition and an activity decomposition, both of which employ the same graphic building block, the SA box, to represent a part of a whole. SA arrows, representing input, output, control, and mechanism, express the relation of each part to the whole.”

“Neither Watt's steam engine nor Whitney's standardized parts really started the Industrial Revolution, although each has been awarded that claim, in the past. The real start was the awakening of scientific and technological thoughts during the Renaissance, with the idea that the lawful behavior of nature can be understood, analyzed, and manipulated to accomplish useful ends. That idea itself, alone, was not enough, however, for not until the creation and evolution of blueprints was it possible to express exactly how power and parts were to be combined for each specific task at hand.”

“Mechanical drawings and blueprints are not mere pictures, but a complete and rich language. In blueprint language, scientific, mathematical, and geometric formulations, notations, mensurations, and naming do not merely describe an object or process, they actually model it. Because of broad differences in subject, purpose, roles, and the needs of the people who use them, many forms of blueprint have evolved, but all rigorously present well structured information in understandable form.”

“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.”

“We never have any understanding of any subject matter except in terms of our own mental constructs of "things" and "happenings" of that subject matter.”

“I realized after I'd been at MIT for a while that I had never even known the semantics of the word "engineering". You see, all my relatives and contacts were medical doctors or biology and chemistry professors. In fact, I'm almost the "black sheep" in the family for not being an MD or Ph.D. because everybody was doing that sort of thing. There was no contact at all with engineering. I didn't even know what the word meant...”

“I just looked in the phone book, and called up the Executive Officer of the Servomechanisms Laboratory (Al Sise) and said, "I'm a math graduate student and would like a summer job. If you could find an electrical engineering student, I'm sure by the end of the summer we could make you an electronic calculator that would beat the pants off that little mechanical thing that Wiener has put together. Are you interested?”

“A lot of people are not familiar with the fact that when Lincoln Lab grew out of the Project Whirlwind (which were just names to me at that point) for the purpose of looking into radar air defense -- processing radar signals with the computer and then using radio controls to defend with fighters and so forth -- Whirlwind had been originally designed as an aircraft simulator for individual airplanes.”

“The artificial intelligence people, the artificial intelligencia,... kept choosing little games to play, and little things that they could master, right? But my whole philosophy has always been give me a really tough problem that's just beyond the state-of-the-art, and give me a whole bunch of users beating on me to get it done. In other words, the real core of what being an engineer is.”

“The real core of what being an engineer is. You have a scientific basis, but when you don't have the science, you put in some bugger factors, some safety factors, and so forth and you get smart enough, and you get the job done anyhow, right? Economically, and as close to on time as you can make it. And if the customer is asking for something that's outlandish, give him what you can, and educate him back to what it is.”

“I introduced what I called "outside-in problem solving," which nowadays is called "top-clown." But I prefer outside-in because outside-in allows you to have many different viewpoints instead of a single top that you stupidly try to get to the bottom of, and things of that sort. came out of that.”

“The APT and CAD Projects had one Air Force sponsorship, but it was actually a combination of about five or six projects, all going in parallel on both hardware and software matters, and I couldn't keep track of things, so I would take Polaroid pictures of the blackboard and then say what we had talked about into my dictating machine and my secretary would type it up.”

“A general theme for what I'm trying to convey and what actually drove me and my very industrious and creative project members over all these years, is... that there is much more to it than pictures. It has to be a picture language. There has to be meaning there, and the meaning is useful. You're trying to solve problems. So it really comes down to man machine problem solving . Better means of communication and expression is what always has driven our work.”

“Even though we started in the days when the equipment itself wasn't able to do very exciting visual things, we were always concentrating on this matter of communication and meaning.”

“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.”

“I was sort of a hellraiser with a bunch of friends, most of whom were squeaking by with C's and D's while I was getting an A-average and should have been doing better. I did a lot of things on my own. I liked to make things with my hands. There was a lot of woodworking, model building, and model railroading. I collected stamps, and did various things in chemistry. I used to make things that exploded, and all that sort of thing. So I evidently got quite a good background in science. I always had a knack for that sort of thing. The hospital had a subscription to Scientific American and Science. So things came every week and I consumed them...”

“With all this science and physics and so forth that I absorbed. I did have one early experience with engineering, however. When we got the Book of Knowledge, I found on one page a diagram for a short-wave radio. I thought it would be neat to try to make a shortwave radio, so I arranged with all the radio repairmen in the town that whenever they were going to junk a radio, they should set it aside and I would pick it up. I got all these old radios -- really classics now -- that I stripped. I had huge transformers and loudspeakers and huge condensers -- the whole works. Boxes full of this stuff. I didn't understand it. I didn't know a thing about it. I just liked to take things apart and learn how to solder. I discovered out of my collection of parts -- with the tuning condensers (with movable plates), the knobs, and all that stuff, that I had what seemed to be needed in this one page diagram of a shortwave receiver.”

“The first paper I ever wrote was "Gestalt Programming" and that was in 1955. The whole idea there was to replace the laborious writing out of detailed programs and all those steps by having analyzed a problem area well enough so that you had what I later came to call a "systematized solution." Then you could compose different problems of this class by just plugging together pieces of program, and they would in turn be controlled by a pushbutton language. The user would make a number of discreet selections. It's just like nowadays it's done with menus, and when you had indicated all the pieces that you wanted to put together--by these mnemonic names and words for things associated with buttons, switches, with one meaning "period," essentially, for that sentence, you see--all these things would be brought together and that would be the man/machine, manual-intervention mode of problem-solving. I took over the term from studying Gestalt psychology, meaning that everything was brought together at once, as a unit, instead of this laborious step-by-step build-up.”
