The Rule of Three states that if a type ever needs to have a user-defined copy constructor, copy assignment operator, or destructor, then it must have all three. The reason for the rule is that a class which needs any of the three manages some resource file handles, dynamically allocated memory, etc , and all three are needed to manage that resource consistently.

Rule of three (C++ programming)

Name any industry and more likely than not you will find that the three strongest, most efficient companies control 70 to 90 percent of the market. Drawing on years of research covering hundreds of industries both local and global, The Rule of Three documents the evolution of markets into two complementary sectors -- generalists, which cater to a large, mainstream group of customers; and specialists, which satisfy the needs of customers at both the high and low ends of the market. Any company caught in the middle "the ditch" is likely to be swallowed up or destroyed.

Sheth and Sisodia show how most markets resemble a shopping mall with specialty shops anchored by large stores. Drawing wisdom from these markets, The Rule of Three offers counterintuitive insights, with suggested strategies for the "Big 3" players, as well as for mid-sized companies that may want to mount a challenge and for specialists striving to flourish in the shadow of industry giants. The book explains how to recognize signs of market disruptions that can result in serious reversals and upheavals for companies caught unprepared.

Such disruptions include new technologies, regulatory shifts, innovations in distribution and packaging, demographic and cultural shifts, and venture capital as well as other forms of investor funding. Years in the making and sweeping in scope, The Rule of Three provides authoritative, research-based insights into market dynamics that no business manager should be without. Read more Read less.

Identifying where a company is in this framework and laying one's strategies against the suggested rules for that position provides an extremely valuable, thought-provoking, and prescriptive tool for strategy development.

If you can't clearly say that you are headed to be one of the three dominant generalist survivors in a market, or a strong product or market niche player, you will probably be in harm's way. Wherever you are, "The Rule of Three" will help you walk through the minefields and around the ditch.

This is not about a business fad. With a deceptively simple principle, "The Rule of Three" richly explains the evolution of industry structures and the appropriate strategic responses. It's built on solid research and powerful insight. I found myself underlining gems on every other page. Whether your company is a full-line generalist or a niche specialist, and especially if it is in the endangered middle, this book is a thoughtful and solid guide for everyone who intends to stay in business for a long time.

Professor Jeffrey Sonnenfeld author of "The Hero's Farewell, " Associate Dean, Yale School of Management Sheth and Sisodia present original research and analysis that reveal a Nobel-prize-quality realization of how mature markets work. No corporate leaders can wisely guide their enterprises through the turbulence of contemporary competitive markets without this book as their navigational map.

Philip Kotler Northwestern University, Kellogg School of Management Sheth and Sisodia have written one of the most provocative and original business books to come out in years. Whether your company functions in your industry as a generalist, a specialist, or is stuck in a ditch, you will find a catalog of strategies for surviving, reviving, or prospering.

This is that book. Read it sooner, rather than later. Supreme Court refused to allow two supermarkets in Los Angeles to merge. Over 3, single-store grocers would still have been doing business in the city. In spite of these statistics, the Court ruled against the merger, citing "the threatening trend toward concentration. Over time, the view that market efficiencies matter and that consumer welfare is actually enhanced by a measure of industry concentration has slowly gained acceptance, although there still are loud complaints from consumer groups that this or that merger will result in higher prices.

In truth, markets remain highly competitive even after such concentration, and industries that have experienced consolidation have seen prices remain stable or actually fall. To be sure, profits are generally higher in concentrated industries, but the prices consumers pay may actually decline. This evidence suggests that efficiency gains are a prime driver of greater profitability and market evolution. For that evolution to be sustainable, markets need both growth and efficiency.

Growth comes primarily from understanding and shaping customer demand, whereas efficiency is a function of operations. Through the cyclical pursuit of these objectives, markets become organized and reorganized over time. Once its basic viability has been established, a start-up industry enjoys high growth but has low efficiency. No matter what criterion is used to measure efficiency -- revenue per customer, revenue relative to assets deployed, revenue per employee, for instance -- the start-up costs are high.

The first shakeout occurs during the industry's initial growth phase to make it more efficient without sacrificing growth. Subsequent attempts to make the industry more efficient come from four key sources or events: the creation of standards, the development of an industry-wide cost structure as well as a shared infrastructure, government intervention, and industry consolidation through shakeouts.

These four drivers force the industry as well as the players in it to become more and more efficient in order to stay competitive. As we will see in this chapter, they can occur at any time and in any order, sometimes independently, sometimes closely dependent on each other. Their primary effect, however, is to promote efficiency and fair competition within an industry such that no one company becomes a monopoly.

In subsequent shakeouts, the industry is reorganized for growth, typically through market expansion, including globalization. Driven primarily by investor demands, companies at this stage are concerned with growth of all kinds: revenue growth, cash flow growth, earnings growth, growth in the number of customers and revenue per customer, and growth in market capitalization.

To continue to attract investment capital and growth, the industry needs to make productive use of all inputs, including capital, labor, and management talent. The Creation of Standards Market inefficiency can hasten the creation of de facto standards. Henry Ford paved the way for one such standard when he devised the highly efficient assembly-line manufacturing process for the Model T.

When standards play a major role and remain largely proprietary, there may not be room for three separate platforms. Eventually, one platform becomes dominant, if not universal. The other platform, if it survives, is relegated to a niche market. The simultaneous existence of two or more standards, as in the case of NTSC and PAL, can be attributed in large part to protectionist ideologies and government regulation. Thanks to a double standard in the worldwide electric industry, tourists must contend with shifting between volts and volts, not to mention remembering to pack a variety of prongs and socket styles; in Europe alone there are some 20 different types of electrical plugs currently in use.

To the delight of those tourists, these types of essentially meaningless and highly inefficient differences will start to go away as the electric industry adopts universal standards and the world at large becomes more driven by market economies.

Already we can see the power of a fully adopted worldwide standard in the World Wide Web. The extraordinarily rapid diffusion of this technology across the globe has resulted in large measure because of that single standard.

Emerging industries today are highly cognizant of this fact, and organizations that set industry standards now occupy an influential place in the world economy. However, it was successful in licensing its technology to Sony, which turned it into a competitive advantage.

Sony first introduced videocassette recorders VCR to the mass market in , but even its "U-Matic" machines and cassettes were too big and expensive. Accordingly, Sony made modifications and repositioned the machines for industrial users.

Next, Sony approached JVC and Matsushita -- two of its biggest competitors -- about establishing a standard based on a new Sony technology that would reduce the size of both machines and cassettes. In , JVC established a video home system VHS project team and charged it with the mission to develop a viable VCR for consumers, not just one that was technologically possible, but something consumers would prefer.

Experimenting with ten different ways of building a home VCR, Sony settled by mid on the Betamax prototype. It set up a new plant to produce 10, units a month, but designed the machine to record for only one hour, reasoning that customers would use it to record television programs for later viewing.

Later, when Sony asked Matsushita and JVC to adopt the Beta format, both refused, citing the one-hour recording limit as a major drawback. After the Betamax was launched, Hitachi tried unsuccessfully to license Betamax technology from Sony, which basically had decided to go it alone. The split between the two formats continued for another ten years. Sony did well at first, in part because of its wide distribution. In and , its market share was over 50 percent, but the company lost ground quickly.

By late , Matsushita with By , VHS had close to 95 percent of world sales. In a show of pragmatism, Sony launched its own line of VHS machines and repositioned Betamax as a high-end system for professionals. Analog cellular telephone systems grew rapidly in Europe in the s, especially in Scandinavia and the United Kingdom.

Because each country developed its own sophisticated systems and networks, the industry was characterized by incompatible equipment and operations. Since mobile phones could operate only within national boundaries, the limited market for each company's equipment meant that economies of scale were poor.

It was not unusual to see executives toting multiple phones depending on the country in which they happened to be conducting business at the time. The imminent creation of the European Union EU made this highly inefficient situation untenable. Members of the European Union were instructed to reserve frequencies in the MHz band for GSM to enable easy "roaming" between countries. GSM service commenced in mid By , there were 36 GSM networks in 22 countries.

GSM was successful in gaining acceptance in non-European markets as well, since it was the most mature mobile digital technology. GSM also proved very successful in Asia, with its huge untapped markets that had no analog legacy to overcome. By , over GSM networks were running in countries, with more than 55 million subscribers.

As of January , GSM networks were operational in countries, with dozens more planned. GSM had million subscribers up from million a year and a half earlier out of million digital subscribers; another 68 million subscribers continued on analog systems. The biggest holdout has been the United States, where the government has played no role in selecting a standard, and where a major rival to GSM, CDMA, has won many converts. Overall, the U. Each network operates independently of the others. While many technology experts argue that CDMA is a superior technology, the advantage appears to be with Europe at this point.

The Rule of Three

The Global Rule of Three lifts the curtain on what this future could look like. The book is packed with great insights into the dynamic forces shaping most industries: above all, that those who know how to truly serve will be the long term winners. Simultaneous coexistence of both the volume driven full line competitors oligopoly and the margin driven niche players monopolistic competitors is unique to competitive positioning Globally. It provides a blue print on how to compete globally especially against growing competition from Multinationals from the Emerging Markets such as China and India. Buy it, you will like it!

It seems that you're in Germany. We have a dedicated site for Germany. In our increasingly digital, mobile, and global world, the existing theories of business and economics have lost much of their appeal with the phenomenal rise of Chindia, the reality of Brexit, the turmoil caused by the Covid pandemic, and the seismic shifting of the global center of gravity from west to east. In the area of innovation, the traditional thinking that a developed country, often the US, will come up with the next major innovation, launch at home first, and then take it to other markets does not ring true anymore. Similarly, the world where conglomerates go bargain-hunting for acquisitions in emerging markets has been turned upside-down. Jagdish N.

The rules prescribe how the default members of a class should be used to achieve these goals systematically. These three functions are special member functions. If one of these functions is used without first being declared by the programmer it will be implicitly implemented by the compiler with the following default semantics:. The Rule of Three claims that if one of these had to be defined by the programmer, it means that the compiler-generated version does not fit the needs of the class in one case and it will probably not fit in the other cases either.
