be as stereotypically bureaucratic as shown in the chart, but it does thrive on a tight structure controlled by top management. Beyond the variation among these tech giants, there are still many more structural possibilities. Think of Zappo's free‐wheeling holacracy or W. L. Gore's lattice arrangements. Every successful company evolves its own unique combination of strategy and structure.

      We often assume that people prefer structures with more choices and latitude (Leavitt, 1978), but this is not always the case. A study by Moeller (1968), for example, explored the effects of structure on teacher morale in two school systems. One was loosely structured and encouraged wide participation in decision making. The other had centralized authority and a clear chain of command. Moeller was surprised to find the opposite of what he expected: faculty morale was higher in the district with a tighter structure. Teachers seemed to prefer clarity of expectations, roles, and lines of authority.

      United Parcel Service, “Big Brown,” provides a contemporary example of the positive benefits of structural certainty and clarity. In the company's early days, UPS delivery employees were “scampering messenger boys” (Niemann, 2007). Since then, computer technology has curtailed employee discretion, and every step from pickup to delivery is highly programmed. Detailed instructions specify placement of packages on delivery trucks. Drivers follow computer‐generated routes (which minimize mileage and left turns to save time and gas). Newly scheduled pickups automatically download into the nearest driver's route plan.

      UPS calculates in advance the number of steps to your door. If a driver sees you while walking briskly to your door, you'll receive a friendly greeting. Look carefully and you'll probably notice the automated van lock the driver carries. Given such a tight leash, you might expect demoralized employees. But, the technology makes the job easier and enables drivers to be more productive. As one driver remarked to us: “We are happy robots.”

      As these examples suggest, tighter structure is sometimes better—and sometimes not. Adler and Borys (1996) argue that the type of structure is as important as the amount or rigidity. There are good rules and bad ones. Formal structure enhances morale if it helps us get our work done. It has a negative impact if it gets in our way, buries us in red tape, or makes it too easy for management to control us. Equating structure with rigid bureaucracy confuses “two very different kinds of machines, those designed to de‐skill work and those designed to leverage users' skills” (p. 69).

      Just about everyone working for the Bavarian automaker—from the factory floor to the design studios to the marketing department—is encouraged to speak out. Ideas bubble up freely and there is never a penalty for proposing a new way of doing things, no matter how outlandish. The company has become an industry benchmark for high‐performance premium cars, customized production, and savvy brand management. (Edmondson, 2006, p. 72)

      Dramatic changes in technology, information flows, and the business environment have rendered old structures obsolete at an unprecedented rate, spawning a new interest in organizational design (Bryan and Joyce, 2007; Joseph and Gaba, 2020; Stanford, 2015). Pressures of globalization, competition, technology, customer expectations, and workforce dynamics have prompted organizations worldwide to rethink and redesign structural prototypes.

      A swarm of items compete for managers' attention—money, markets, people, and technological competencies, to name a few. But a significant amount of time and attention must be devoted to social architecture—designing structures that help people do their best:

      CEOs often opt for the ad hoc structural change, the big acquisition, or a focus on where and how to compete. They would be better off focusing on organizational design. Our research convinces us that in the digital age, there is no better use of a CEO's time and energy than making organizations work better. Most companies were designed for the industrial age of the past century, when capital was the scarce resource, interaction costs were high and hierarchical authority and vertically integrated structures were the keys to efficient operation. Today superior performance flows from the ability to fit these structures into the present century's very different sources of wealth creation. (Bryan and Joyce, 2007, p. 1)

      Basic Structural Tensions

      Division of labor—or allocating tasks—is the keystone of structure. Every living system creates specialized roles to get important work done. Consider an ant colony:

      Small workers … spend most of their time in the nest feeding the larval broods; intermediate‐sized workers constitute most of the population, going out on raids as well as doing other jobs. The largest workers … have a huge head and large powerful jaws. These individuals are … soldiers; they carry no food but constantly run along the flanks of the raiding and emigration columns. (Topoff, 1972, p. 72)

      Like ants, humans long ago discovered the virtues of specialization. A job (or position) channels behavior by prescribing what someone is to do—or not do—to accomplish a task. Prescriptions take the form of job descriptions, procedures, routines, protocols, or rules (Mintzberg, 1979). On one hand, these formal constraints can be burdensome, leading to apathy, absenteeism, and resistance (Argyris, 1957, 1964). On the other, they help to ensure predictability, uniformity, and reliability. If manufacturing standards, aircraft maintenance, hotel housekeeping, or prison sentences were left solely to individual discretion, problems of quality and equity would abound.

      Once an organization spells out positions or roles, managers face a second set of key decisions: how to group people into working units. They have several basic options (Mintzberg, 1979):

       Function: Groups based on knowledge or skill, as in the case of a university's academic departments or the classic industrial units of research, engineering, manufacturing, marketing, and finance.

       Time: Units defined by when they do their work, as by shift (day, swing, or graveyard shift).

       Product: Groups organized by what they produce, such as detergent versus bar soap, wide‐body versus narrow‐body aircraft.

       Customer: Groups established around customers or clients, as in hospital wards created around patient type (pediatrics, intensive care, or maternity), computer sales departments organized by customer (corporate, government, education, individual), or schools targeting students in specific age groups.

       Place: Groupings by geography, such as regional or international offices in corporations and government agencies or neighborhood schools in different parts of a city.

       Process: Grouping by a flow of work, as with “the order fulfillment process. This process flows from initiation by a customer order, through the functions, to delivery to the customer” (Galbraith, 2001, p. 34).

      Creating roles and units yields the benefits of specialization but creates challenges of coordination and control—how to ensure that diverse efforts mesh. Units tend to focus on their separate priorities and strike out on their own, as New York's police and fire departments did on 9/11. The result is suboptimization—individual units may perform splendidly in terms of their own goals, but the whole may add up to much less than the sum of the parts. This problem plagued Tom Ridge, who was named by President George W. Bush as the director of Homeland Security in the aftermath of the 9/11 terrorist attacks. His job was to resolve coordination failures among the government's many different
