The Invention of Battlezone – IEEE Spectrum

King Camp Gillette decreased the value of the razors, and the demand for razor blades elevated. The historical past of IT accommodates quite a few examples of this phenomenon, too.

I contend, furthermore, that there are nonetheless different regularities within the area of computing that is also formulated in a trend just like that of Moore’s and Metcalfe’s relationships. I wish to suggest 4 such legal guidelines.

Legislation 1. Yuletide’s Legislation of Complementarity

I named this legislation after George Udny Yuletide (1912), who was the statistician who proposed the seminal equation for explaining the connection between two attributes. I formulate this legislation as follows:

If two attributes or merchandise are enhances, the worth/demand of one of many enhances will probably be inversely associated to the value of the opposite complement.

In different phrases, if the value of 1 complement is decreased, the demand for the opposite will enhance. There are a number of historic examples of this legislation. One of many well-known ones is the advertising of razor blades. The legendary King Camp Gillette gained market domination by making use of this rule. He decreased the value of the razors, and the demand for razor blades elevated. The historical past of IT accommodates quite a few examples of this phenomenon, too.

The case of Atari 2600 is one notable instance. Atari video video games consisted of the console system {hardware} and the read-only reminiscence cartridges that contained a recreation’s software program. When the product was launched, Atari Inc. marketed three merchandise, particularly the Atari Video Laptop System (VCS) {hardware} and the 2 video games that it had created, the arcade shooter recreation Jet Fighter and Tank, a heavy-artillery fight title involving, not surprisingly, tanks.

Crucially, Atari engineers determined that they’d use a microchip for the VCS as a substitute of a customized chip. Additionally they made positive that any programmer hoping to create a brand new recreation for the VCS would have the ability to entry and use all of the interior workings of the system’s {hardware}. And that was precisely what occurred. In different phrases, the designers decreased the boundaries and the price essential for different gamers to develop VCS recreation cartridges. Greater than 200 such video games have since been developed for the VCS—serving to to spawn the sprawling US $170 billion international online game trade immediately.

An identical legislation of complementarity exists with pc printers. The extra reasonably priced the value of a printer is stored, the upper the demand for that printer’s ink cartridges. Managing complementary parts nicely was additionally essential to Apple’s profitable the MP3 participant wars of the early 2000s, with its now-iconic iPod.

From a strategic perspective, know-how corporations in the end have to know which complementary factor of their product to promote at a low worth—and which counterpoint to promote at the next worth. And, because the economist Bharat Anand factors out in his celebrated 2016 e book The Content material Lure, proprietary enhances are typically extra worthwhile than nonproprietary ones.

Legislation 2. Hoff’s Legislation of Scalability

This legislation is known as after Marcian Edward (Ted) Hoff Jr.—the engineer who satisfied the CEO of Intel to use the legislation of scalability to the design and growth of processors. Actually, the phenomenon of scalability was well-known within the vehicle trade earlier than it made a big impression on the computing trade. Henry Ford was a notable instance of the appliance of this scalability legislation. Henry Ford’s firm was maybe the primary firm to use this legislation on a grand scale. Ford produced the Mannequin T, which was the primary mass-produced automotive. On the core of Henry Ford’s achievement was the design of an vehicle that was made for mass manufacturing. Ford’s engineers broke down the meeting strategy of the Mannequin T into 84 discrete steps. The corporate standardized all of the duties and assigned every employee to do only one job, thus standardizing the work every employee carried out as nicely. Ford additional constructed machines that would stamp out components routinely. Along with Ford’s revolutionary growth of the primary transferring meeting line, this manufacturing system minimize the time to construct a automotive from 12 hours to about 1.5 hours. The Mannequin T might be the paradigmatic instance of how standardization permits designing processes for scalability.

Till the early Sixties, every IBM system had its personal distinct working system, processor, peripherals, and software software program. After the acquisition of a brand new IBM pc, prospects needed to rewrite all their present code.

Intel additionally mastered the legislation of scalability early in its historical past. In 1969, Busicom, a Japanese firm, approached Intel about constructing customized chips to be used in its programmable computer systems. Gordon Moore was not inquisitive about a customized chip as a result of he knew that it could not be scalable. It was the hunt to create a scalable product that led Intel’s Ted Hoff to partition the chip right into a general-purpose logic processor chip and a separate read-only reminiscence (ROM) chip that saved an software program. As Albert Yu exhibits in his historical past of Intel, Creating the Digital Future, the fledgling semiconductor firm’s general-purpose processor, the 4004, was scalable and just about bequeathed the world the {hardware} structure of the fashionable pc. And it was Hoff who redesigned the 4004 to scale. Hoff’s Legislation of Scalability may thus be described as follows:

The potential for scalability of a know-how product is inversely proportional to its diploma of customization and instantly proportional to its diploma of standardization.

In sum, the legislation predicts {that a} know-how element or course of that has a excessive diploma of customization and/or a decrease diploma of standardization will probably be a poor candidate for scaling.

Legislation 3. Evans’s Legislation of Modularity

This legislation derives its title from Bob Overton Evans. He was the engineer who within the early Sixties persuaded IBM’s chairman, Thomas J. Watson Jr., to discontinue IBM’s know-how design strategy, which had produced a hodgepodge of incompatible computer systems. Evans advocated that IBM ought to as a substitute embark on the event of a household of modular computer systems that may share peripheries, directions, and customary interfaces. IBM’s first product household beneath this new design rubric was referred to as System/360.

Previous to this period, IBM and different mainframe pc producers produced programs that had been distinctive. Every system had its personal distinct working system, processor, peripherals, and software software program. After the acquisition of a brand new IBM pc, prospects needed to rewrite all their present code. Evans satisfied CEO Watson {that a} line of computer systems ought to be designed to share most of the identical directions and interfaces.

If a paper is copied 4 occasions, one can now share the useful resource with 5 folks. However digitize the doc and the value-creation alternatives are multiplicative moderately than additive.

This new strategy of modular design meant that IBM’s engineers developed a typical structure (the specification of which capabilities and modules will probably be a part of the system), widespread interfaces (an outline of how the modules will work together, match collectively, join, and talk), and customary requirements (a definition of shared guidelines and strategies that may be used to realize widespread capabilities and duties). This daring transfer on Large Blue’s half created a brand new household of computer systems that revolutionized the pc trade. Prospects may now defend their investments as a result of the directions, software program, and peripheries had been reusable and appropriate inside every pc household.

Evans’s Legislation could possibly be formulated as follows:

The inflexibilities, incompatibilities, and rigidities of advanced and/or monolithically structured applied sciences could possibly be simplified by the modularization of the know-how constructions (and processes).

This legislation predicts that the appliance of modularization will scale back incompatibilities and complexities.

One additional instance of Evans’s Legislation will be seen within the software program growth trade, because it has shifted from the “waterfall” to the agile software program growth methodology. The previous is a linear and sequential mannequin stipulating that every mission section can start solely the earlier section has ended. (The title comes from the truth that water flows in just one path down a waterfall.) Against this, the agile growth strategy applies the legislation of modularization to software program design and the software program growth course of. Agile software program developments are typically extra versatile, extra responsive, and quicker.

In different phrases, modularization of software program initiatives and the event course of makes such endeavors extra environment friendly. As outlined in a useful 2016 Harvard Enterprise Evaluate article, the preconditions for an agile methodology are as follows: The issue to be solved is advanced; the options are initially unknown, with product necessities evolving; the work will be modularized; and shut collaboration with finish customers is possible.

Legislation 4. The Legislation of Digitiplication

The idea of digitiplication is derived from two ideas: digitalization and multiplication. The legislation stems from my very own examine and observations of what occurs when a useful resource is digitized or a course of is digitalized.

The legislation of digitiplication stipulates that each time a useful resource or course of is digitalized, its potential worth grows in a multiplicative method.

For instance, if a paper is copied 4 occasions, one can now share the useful resource with 5 folks. However digitize the doc and the value-creation alternatives are multiplicative moderately than additive.

Take into account the instance of a retail retailer. The shop’s gross sales reps, tasked with promoting bodily merchandise to particular person folks, are in a position to service just one buyer at a time. Nonetheless, if the identical retail setting is positioned on-line, many purchasers can view the shop’s services and products. Digital textual content can even simply be remodeled into an audio format, offering a distinct type of worth to prospects. Search performance inside the retailer’s stock in fact provides one other layer of worth to the shopper. The shop’s managers can even monitor what number of prospects are viewing the shop’s web site’s pages and for a way lengthy. All of those enhancements to the shopper’s (and retailer’s) expertise present totally different sorts of worth. As will be seen by these examples, the digitalization of a useful resource, asset, or course of creates multiplicative moderately than additive worth.

As an extra instance, Amazon founder Jeff Bezos first started digitizing knowledge about books as a strategy to facilitate extra and better e book gross sales on-line. Bezos shortly remodeled Amazon right into a digitiplication engine by changing into a data-centric e-commerce firm. The corporate now advantages from the multiplicative results of digitalized processes and digitized info. Amazon’s search, choice, and buy capabilities additionally enable the corporate to document and produce knowledge that may be leveraged to foretell what the shopper desires to purchase—and thus choose which merchandise it ought to present to prospects. The digitization of buyer suggestions, vendor rankings, and vendor suggestions creates its personal dimension of multiplicative worth.


These 4 legal guidelines will be helpful for engineers and designers to pose questions as they start to develop a product. For instance: Do buyer necessities lend themselves to a product design that could possibly be scaled (or mass-produced)? Would possibly the purposeful necessities they’re working with be happy by the event of a modular product design? Might Yuletide’s Legislation of Complementarity present cues towards mass manufacturing or modular design alternate options? Might product enhances be developed in-house or outsourced? Software program engineers may additionally be led towards productive questions on how knowledge could possibly be digitized, or how particular processes could possibly be digitalized to leverage the legislation of digitiplication.

The fields of IT and electrical engineering and pc science (EECS) have develop into important disciplines of the digital age. To cross alongside probably the most succinct and related formulations of amassed information to this point to the subsequent era, it is incumbent on teachers and thought leaders in these important technical fields to translate classes discovered into extra formalized units of theorems and legal guidelines. Such formulations would, I hope, allow present and future generations of IT and EECS professionals to develop probably the most helpful, related, impactful, and certainly typically even disruptive applied sciences. I hope that the proposed 4 legal guidelines on this article may assist to set off a bigger dialogue concerning the want for and relevance of recent legal guidelines for our disciplines.
