088 – Management as servant, not master

For most of the history of management (beginning in the mid-1800s), organizations included command and control structures and top-down information flow. Managers were viewed as the boss, the big cheese, the man, or master within a hierarchical system of control. This is an authoritarian model of organization, where management drives the organization as a machine, and employees are just cogs among the big wheels. The basic idea underlying this tradition is that firms make money for their owners. Managers control the individuals in the firm, and a bureaucracy introduces rules, plans, and reports to create a predictable and stable organization. This is all in the service of efficiency and productivity. When things go awry, managers introduce cost-cutting and downsizing. The basic principles become self-reinforcing and interlocking.

The industrial revolution (from which modern capitalism emerged) spurred on the growth of hierarchical organizations as capital equipment (i.e., machines) began to take over the workplace, driven, in turn, by water power, steam power, and electric power. As the 19th Century gave way to the 20th Century, productivity rose quickly. Employees no longer made things by hand but learned instead to tend the equipment that made things. Looking back over the decades, Peter Drucker credited the management principles of Frederick Winslow Taylor with a 50-fold increase in the productivity of manual work during the 20th Century, an increase upon which rested, he noted, “all of the economic and social gains” of the times.

Today, despite the rise in productivity and living standards in the 20th Century, it is not clear that they can be maintained as we move further into the 21st Century. Productivity growth has been weak, and getting weaker, for decades in most industrialized countries. If the current pace continues, living standards in the USA and highly developed countries around the world will stagnate for most workers.

While authoritarian styles of management are still prevalent in many sectors of the economy, they are coming to represent an out of date, last century paradigm that is wrong-headed on many levels. If we need fresh evidence that management is broken, we only have to look at the 2017 numbers on worker engagement from Gallup. Only 21% of employees strongly agree that they are managed in a way that motivates them to do outstanding work. Overall, only 33% of US workers report that they are actively engaged in their work. Today, when so many business models are being disrupted by Internet-based newcomers, every organization needs to innovate to stay relevant, and authoritarian command and control structures just don’t get the job done. They hinder innovation more than they support it.

New ideas are emerging to encourage greater freedom and innovation in the workplace and to increase the speed of action. Broadly, these could be called network models rather than hierarchical models. Instead of control flowing downward through a hierarchy of people with fixed managerial roles (and sign-off authority), the new approaches provide structure through a flat network of individuals or teams held together by unifying philosophical principles, evolving roles, and a belief in individual responsibility. Examples of these ideas include (1) servant-leadership, (2) self-management (or holacracy), and (3) agile/scrum techniques (or radical management).

In our first example, the servant leadership approach proposes that the best leaders think and act as a servant to those they are leading. The approach is rooted in ancient philosophy, including Chinese Taoism and early Christianity. In the New Testament, for instance, Jesus tells his disciples (Mark 9:35), “If anyone wants to be first, he must make himself last of all and servant of all.” In modern times, Robert K. Greenleaf outlined the characteristics of the servant leader, first in an essay in 1970, and later in his 1977 book, Servant Leadership. Greenleaf taught that a servant-leader tends to the growth and well-being of the people they lead and the communities to which they belong. While traditional leadership serves to accumulate power at the top of an organizational hierarchy, the servant-leader shares power, putting the needs of others first in service to the common good. This is a model that has worked well in the non-profit sector, including churches. Where churches have run into trouble, however, is when they have strayed from this model by allowing the accumulation of power, prestige, and wealth at the top. Ideas similar to servant leadership can also be found in other techniques discussed below.

Our second example is called self-management. According to the Morning Star Self-Management Institute, self-management “is an organizational model where the traditional functions of a manager (planning, coordinating, controlling, staffing and directing) are pushed out to all participants in the organization instead of just to a select few. Each member of the organization is personally responsible for forging their own personal relationships, planning their own work, coordinating their actions with other members, acquiring requisite resources to accomplish their mission, and for taking corrective action with respect to other members when needed.”

The Morning Star Company is a California-based wholesale supplier of tomatoes and tomato products. The company was started in 1970 by Chris Rufer, a college student and one-truck owner/operator, who hauled tomatoes to processing plants. Rufer envisioned a firm where there were no bosses, only philosophical principles to which everyone would adhere. According to a 2016 Los Angeles Times article, Morning Star’s idea of self-management is an early form of what has become known as ‘holacracy’, a philosophy that takes its name from the ‘holarchy’ built of interdependent but autonomous units (called ‘holons’). Early ideas were first described by Arthur Koestler in his 1967 psychological treatise “The Ghost in the Machine.”

Zappo’s, now a Las Vegas-based shoe retailing arm of Amazon, is a well-known practitioner of holacracy. According to Tony Hsieh, CEO of Zappos, “research shows that every time the size of a city doubles, innovation or productivity per resident increases by 15 percent. But when companies get bigger, innovation or productivity per employee generally goes down. So, we’re trying to figure out how to structure Zappos more like a city, and less like a bureaucratic corporation. In a city, people and businesses are self-organizing. We’re trying to do the same thing by switching from a normal hierarchical structure to a system called Holacracy, which enables employees to act more like entrepreneurs and self-direct their work instead of reporting to a manager who tells them what to do.”

In holacracy, decision making is vested in self-organizing teams (structured around work roles) rather than a rigidly-dictated management hierarchy. Holacracy brings groups of people together around a single purpose, strengthening the group’s relationship with the organization’s purpose, and then clarifying and optimizing the way people get work done together. (In episode 061 of this podcast, I interviewed Karim Bishay, principal consultant at Living Orgs. We talked about holacracy in some detail in that episode.)

Our third example focuses on agile and scrum techniques, which began as a way for rapid product development in software projects by staying close to customer needs. Scrum is a methodology that allows a team to self-organize and make changes quickly, in accordance with agile principles. A scrum master is the facilitator and process manager for an agile development team. Steve Denning, in his book Radical Management (2010), describes the manager’s job as one of enabling self-organizing teams to delight the customer. Much of what Denning describes came out of the so-called ‘Agile’ movement which started by focusing on the improvement of software project implementation using self-organizing teams, ‘scrum’ techniques, and scheduled meetings every couple of weeks to discuss progress. Scrum teams engage in sprints, with short bursts to achieve a short-term objective and then report back. Agile principles and practices seem to work well in software development, where they started, but many of the agile techniques have expanded into wider business settings in recent years. It should be noted that agile methods for project management are broadly part of the quality movement, and have much in common with TQM (i.e., total quality management) for products and services.

These examples point to the emergence of new forms of organization that cast management more as servant than master. While management is still about getting work done, some fundamental things have changed, and are pushing society in this direction. First, the demand-side (the customer) is now fully in control. He/she can go elsewhere very easily. There are so many choices and so much overcapacity, particularly in the manufacturing sector, that the customer can be picky. Second, all workers are knowledge workers now. Today’s products and services have significant amounts of embedded knowledge incorporated within them, and instruction manuals and training programs need to be available to translate the full value of the offering via the manufacturer’s recommendations. Likewise, knowledge workers need to be given freedom to innovate as they undertake the work rather than simply commanded to do it, as in the past. The knowledge worker, by definition, knows more about the work than any potential boss, so it makes sense to push decision making out to the periphery where knowledge workers live and work.

Let me finish today by pointing out that Management by Positive Organizational Effectiveness (M+OE), the form of management advocated on this podcast, plays well with network-based management approaches that push decision making out to the organization’s periphery. Under M+OE, every organization has the same goal, to be effective within its environment. The overriding directive for each organization is to serve its environment and be rewarded in return. The job of management is simplified because top executives do not need to set objectives. Rather, product and service teams at the periphery are challenged to consider a key question every day, “How can we serve our environment well today?” Businesses, government agencies, and nonprofits have the same challenge. It is a question that is difficult to answer in a bureaucratic, top-down, command-and-control management system. It is best handled by flexible teams of knowledge workers intent on the success of individual offerings in the environment. Of course, we are not suspending the principles of accounting, economics, or finance, in making such decisions, but these are not necessarily constraints. The approach focuses on staying close to the customer, being passionate about serving, and looking for the presence of expected demand-side responses to verify effectiveness.

Given its features, Management by Positive Organizational Effectiveness offers the promise of a new style of venture capitalism. Consider the possibilities of taking a public company private, removing the C-suite team, installing servant leaders where necessary, and using the philosophy embedded within Management by Positive Organizational Effectiveness as the way to think about the job of management going forward. The company would be expected to remain private for at least five years until it met the tests of true greatness. In this scenario, management can fulfill a higher role as servant, rather than master.

087 – Back to the Pleistocene

Anthropologists tell us that anatomically modern humans (i.e., Homo Sapiens) emerged about 300 thousand years ago during the Pleistocene era on the African savannas. For over 95% of their history (until the present day), modern humans have been exclusively hunter/gathers, that is, they explored the bounty of nature in small bands, adapting their behavior as they encountered different environments. Few management skills were required other than communication and teamwork. The goal was the discovery and exploitation of food and other resources necessary for survival and continuation of the species.

While Homo Sapiens are not the first species that used stone tools, they took tool making to the next level to better extract value from, and survive in, different environments. In one sense, they were early knowledge workers. They developed and applied a body of knowledge about their environment to the search for food and other resources necessary for survival. A sense of freedom was available in this early form of group organization and management. Specialization of labor was likely along gender lines; the men did the hunting, while the women did the gathering (and nurtured the young).

About 12,000 years ago, horticulture and agriculture first emerged in what is called the Neolithic revolution. Key to this transformation was the domestication of certain plants and animals that could be produced using cultivation and herding practices. For example, the goat was domesticated about 10,000 years ago in Iran, emmer wheat about 11,000 years ago in the southern Levant, and rice about 10,000 years ago in China. The emergence of agriculture-based societies enabled permanent settlements and significant population growth. Whereas hunter/gathers survived with small team-based work groups, early agriculture-based settlements led to more formal types of organization. Early institutions undertook these functions (e.g., in the fertile crescent from Egypt to Mesopotamia) as irrigation, seed distribution, and grain storage were likely organized to avoid crop failure and famine. Widespread single-crop agriculture did not become common until the Bronze Age, about 6,000 years ago.

With settlements, further specialization of labor took place. Artisans such as the butcher, the brewer and the baker that Adam Smith idolized in his book Wealth of Nations (1776) became common. A series of industrial revolutions, beginning in the late 1700s in England and continuing into the 1900s, spread throughout much of the developed world as water power, steam power, and electric power were applied in turn to the production processes of factories and other venues.

The essence of modern capitalism is investment in, and the substitution of, capital equipment for manual work in the search for efficiency gains. By the early-1800s, a textile factory using a 100 HP steam engine could do the work of 880 men. One documented example ran 50,000 spindles, employed 750 workers, and could produce 226 times more than it did before the introduction of steam.

Still, up until the 1840s, US firms remained very small (just a few people). The owners managed, and the managers owned. At the time, transportation and distribution were facilitated by animals on the land, and by wind power on the seas. Commercial steamships were not common until after 1850. Bureaucracy was the new management technology of the mid-1800s and enabled the growth of large organizations, complete with middle management, such as the railroad and telegraph companies of the day.

So, is management best when it controls or when it enables freedom? If you look at the definition of management in the dictionary, you will come away thinking that it is largely about constraint — dealing with or controlling people and resources to achieve reproducibility and productivity. Since the Neolithic Revolution in agriculture, management has gradually imposed order and control on processes, in the service of normalization, standardization, and efficiency.

Certainty, management focused on efficient process control can provide benefits, depending upon environmental conditions. For example, total quality management (TQM) was a winning strategy for Japanese car companies that were conquering the American market in the 1970s and 1980s. Consumers of the time were looking for small, reliable, and efficient cars following OPEC-led gasoline price increases. So, normalization and standardization, and the reduction of defects that comes through various management approaches have been historically important beginning with the agricultural revolution, through the industrial revolution, and beyond. This thread of the story of management is primarily about efficiency gains, as well as meeting the demands of the market for quality.

Now, however, we are in the first half of the 21st Century. The environment has changed and is changing still. The introduction of the Internet in the early 1990s has served to disrupt the business models of many brick and mortar enterprises. Increasingly, large and formerly dominant organizations have become walking zombies as their business models have come under threat from upstart online competitors. For instance, Amazon, Netflix, and Airbnb are capturing, and bringing into their orbit, large portions of the transactions in various retail, entertainment, and hotel spaces, taking business from established brick and mortar players. Internet-based players are creating new intermediation models on a large scale, not tied to a specific location on the map but ubiquitous in cloud-based servers.

There has always been a tension between human agency, such as the individual’s freedom to act and to realize his or her dreams, and the organization’s need to control, normalize, and standardize processes to create reproducibility. Yet today, many workers are feeling trapped in their jobs, bound by bureaucratic processes and soul-draining performance management systems that prioritize adherence to key performance indicators (KPIs) over worker freedom and innovation. At a time when firms scarcest resource is innovation and creativity, management control remains heavy-handed (because it can). Gary Hamel notes that although most employees can purchase a $20,000 car in their personal lives, they need to get official permission to purchase a $200 office chair in their lives as an employee. What’s up with that?

Ironically, the hottest management trends of today (small agile teams using scrum techniques) are something of a throwback to the Pleistocene bands of early humans that exploited their environment through hunting and gathering techniques for survival. Exploring new environments and changing conditions requires freedom of action, and it is time for management to loosen control. Indeed, organizations could think of themselves as being in the Pleistocene again, in need of a modern band of knowledge workers to explore and understand the changing environment and identify new resources for survival. The next time you run into a C-suite executive that wants to impose KPIs on your unit, tell him or her to loosen up and go back to the Pleistocene. Homo Sapiens operated quite successfully in that way for over 95% of human history. It would be a return to our roots.

Unfortunately, today’s management philosophy and practice stand in the way. It is the programming and conditioning between our ears that holds us back. We can’t get to a better future if maximization of profit and shareholder value continue to be prime directives. In fact, these are merely arbitrary and self-serving goals that are unconnected to natural law.

A new management philosophy is required. From first principles, we know that an organization must find ways to exchange benefits with its environment if it is to survive. A new approach to management is emerging which acknowledges and accommodates this reality. It is called Management by Positive Organizational Effectiveness. It holds that the goal of every organization is the same, that is, to be effective within its environment. An organization becomes effective within this framework by serving its environment and being rewarded in return, exchanging different types of benefits in the process that are needed to survive and thrive. This approach places effectiveness above efficiency in the hierarchy of organizational performance.

When the goal of every organization is the same, management is no longer free to set objectives from the top down. Rather, teams at the periphery are empowered to ask, “how can I best serve my environment today.” Like the freedom of the Pleistocene bands, these new teams are set free to create a better future around specific product and service offerings, a future that not only benefits them, but that serves to strengthen the common good as well. Perhaps we have much to learn from our Pleistocene roots.

086 – Why does worker productivity remain low?

Worker productivity is the output of goods and services per hour worked. In the broad terms of an industry, productivity is the gross output of industry sales divided by the number of workers allocated to produce the output.

After World War II, worker productivity in the USA improved significantly due to the investments made by companies in the technological advances of the period. Increasingly, American products were in high demand as much of the rest of the world rebuilt after the war. The US government provided educational opportunities largely free of cost to returning service personnel, who then entered the workforce with improved skills. Typical of the times, firms retained and invested profits in their growing businesses. It was a period that is now remembered fondly as being a golden age in the American homeland. During the period 1947-1973, non-farm worker productivity grew at a robust 2.8 percent per year (according to the Bureau of Labor Statistics).

By contrast, the last decade (2007-2016) has seen non-farm worker productivity grow at an anemic 1.2 percent per year. Granted, the USA (and much of the world) was working its way out of a deep recession during the period, but that may not fully explain the low rate of productivity growth. Productivity growth has been weak, and getting weaker, for decades in most industrialized countries. If it continues at this pace, living standards in the USA and highly developed countries around the world will stagnate for most workers.

Economists have provided a number of competing explanations to try to explain what is going on:

1. management strategies that worked in the past have been widely implemented and may no longer contribute to productivity (e.g., efficiency improvements like downsizing, re-engineering, KPIs, etc.);

2. the slow down in capital investment following the financial crisis of 2008 has probably contributed to low productivity;

3. measurement error may be a factor, since the measurement of productivity is notoriously difficult;

4. a delay or lag in productivity gains from any investments in new technology (which may be realized in coming years);

5. a fall in wages across the globe during the recession has put pressure on workers compensation in the USA;

6. the psychological pressures on workers that do not feel secure in their current position;

7. continued weak growth in demand; and

8. the continuing shift from a manufacturing to a service-based economy.

The above explanations generally reflect common beliefs among economists about the nature of the current problems surrounding productivity.

Now let me focus on another possibility — the underlying negative effect of current management practices on productivity and worker engagement. As Gary Hamel (London Business School) has pointed out, many organizations remain inertial, incremental, and insipid in the face of the creative destruction going on in the world economy. The top-down, command and control, and bureaucratic nature of most organizations is hampering innovation at a time when innovation is key to survival and growth.

Clayton Christensen (Harvard Business School) has found another management behavior that is limiting innovation and growth. It relates to the financial metrics (e.g., IRR) being used in public companies. First, Christensen outlines three common types of innovation:

1. Market-creating innovation. This type of innovation creates growth in the economy as it discovers ways to take expensive products that have limited appeal and makes them widely available at lower cost to a mass market. The evolution of the computer from the mainframe to the personal computer, to the smartphone, is an example. The benefits of this type of innovation in the financial metrics are apparent only in the long term (5-10 years), while there is likely to be a short-term decrease until the investments pay off.

2. Sustaining innovations. This type of innovation makes good products better but doesn’t create growth, due to the substitution of new for old. For example, if you buy a Toyota Prius hybrid, you will not be buying a Camry.

3. Efficiency innovations. This type of innovation tries to do more with less, through downsizing, rightsizing, and other cut back measures. It generally eliminates jobs but frees up cash. The benefits of this type of innovation are apparent in the short term in the financial metrics.

Since efficiency innovations provide short-term results which can be seen quickly in the financial metrics, but market-creating innovation only pays off in the long term, it is the efficiency improvements that usually win out. This too can help explain low worker productivity in recent decades.

A recent article in Harvard Business Review (March 1, 2017) noted that great companies obsess over productivity rather than efficiency, since the benefits of efficiency improvements have now played out. Despite weak top-line growth in many years, the 1990s and 2000s saw the earnings growth of S&P 500 companies run nearly three times the rate of inflation due to improvements in efficiency; however, starting with the quarter ending March 31, 2015, S&P 500 earnings began falling and has remained negative ever since. Without top line growth, continuing efforts to achieve improvements in efficiency eventually hit a proverbial brick wall. The same HBR article found three fundamental tenets of a productivity mindset that executives need to understand:

1. Most employees want to be productive, but the organization often gets in the way;

2. A company’s talented “difference makers” are often put in roles that limit their effectiveness; and

3. Employees have plenty of discretionary energy that could be devoted to their work, but many are not sufficiently motivated to do so.

As is often the case with this podcast, we have once again found a need to reinvent management for the 21st Century and beyond. Efficiency improvements have worked their way through companies in recent decades, but have taken a significant toll on future growth. The current path on which many public corporations find themselves is not sustainable. Now we need to create corporations that invest for the future, in workers and their work, by providing the freedom and the tools to do creative and innovative work. It seems that innovation is the only likely path out of the current low productivity regime.

To find this path, I recommend a new management approach that we have discussed before on this podcast, and which is described in my 2017 book, Become Truly Great: Serve the common good through Management by Positive Organizational Effectiveness.

085 – We are all knowledge workers now

Peter Drucker predicted in his 1959 book, The Landmarks of Tomorrow, that the most valuable assets of a 21st Century institution (business or non-business) would be knowledge workers and their productivity. In this episode, I explore this idea, and how it has played out (since we are almost 60 years downstream from Drucker’s prediction). Not only was he largely right, but I argue that we are all knowledge workers now due to the nature of our present reality.

This is also our last episode of 2017, and I take the opportunity to look back on what has been presented in the podcast in the last year or two, and consider whether 2018 will continue in a similar vein. I also mention some new offerings that I am considering for the coming year and request your inputs.

084 – Three reasons management is broken (but can be fixed)

If we need fresh evidence that management is broken, we only have to look at the 2017 numbers on worker engagement from Gallup. Only 21% of employees strongly agree that they are managed in a way that motivates them to do outstanding work. Overall, 33% of US workers report that they are actively engaged with their work.

Management’s seeming inability to consistently engage workers in their work stems from three primary causes, in my view:
1. management retains goal setting as one of its primary roles;
2. management focuses their attention on efficiency rather than effectiveness; and
3. management acts as if compensation (pay, in its various forms) is a more powerful motivator for workers than intrinsic reward (internal motivation).

In short, management is applying problematic last-century management approaches (largely designed for manual workers rather than knowledge workers) to this century’s problems.

What to do? A new and unconventional approach to management promises to fix these problems (termed Management by Positive Organizational Effectiveness). It provides a process to transform an uninspired organization into a truly great organization.

Within the new approach, the goal of every organization is the same, that is, to be effective within its environment. It means that an organization serves its environment (exchanging benefits with it) and is rewarded in return. High powered executives are not needed to set goals when every organization has the same goal. This has the added effect of focusing management attention primarily on effectiveness, setting efficiency aside until effectiveness has been achieved. The new approach empowers workers at the periphery to ask how they can serve their environment more effectively today, and frees them up to do their best, most creative work.

081 – Effective entrepreneurship

In this episode, I explore three ideas about effective entrepreneurship:

  1. the most effective entrepreneurs create a platform for others to build upon and benefit from, one that users can interact with on a continuing basis (e.g., Apple’s iPhone, Leggos, Skype) ;
  2. effective entrepreneurs understand the game they are playing (i.e., what constitutes visible progress and success); and
  3. effective entrepreneurs enlist a hierarchy of benefits in their offerings (e.g., financial, economic, social, psychological).

Overall, effective entrepreneurship is about successfully converting the entrepreneur’s supply-side intentions into demand-side behaviors by continually testing for expected responses to a hierarchy of benefits among potential demand-side actors.

080 – Adventures in Capitalism

Consider how an upbeat story about a business (Shake Shack) was distorted on social media, eliciting some negative responses in which people question the underlying motivation of management. There seems to be a dominant, and rather negative narrative that plays in the back of people’s minds about capitalism, providing a context in which to interpret daily events. Clearly, capitalism is not working for everyone.  This episode suggests a partial answer.

079 – Claim a niche and serve it

It is said that the fox knows many things, but the hedgehog knows one big thing. Whether generalist or specialist, an organization needs to claim a niche and serve it so well that the competition is irrelevant. In doing so, an organization can carve out a continuing role in its ecosystem. This episode explores (among other things) how Marriott, Hyatt, Hilton and Starbucks have created a mutually beneficial ecosystem that serves convention goers in downtown Atlanta (USA).

078 – The Power of Story


In this episode, I tell three stories which illustrate the power that this form of expression can have. Stories knit threads together, shape how we see things, and derive power from the outcomes that they describe. If you are going to change the world, it helps to first illustrate how to change a small part of it in a story.
