The Executive PhD program that Peter Drucker, “the Father of Modern Management,” and his dean, Paul Albrecht, developed at Claremont Graduate University in 1975 was the first accredited PhD intended for future top executives. According to Albrecht, this PhD taught the “Drucker Difference” for those “with top management potential.” It was and is expensive.


There were only ten students in the first cohort, and only one of the ten completed the program. This individual eventually rose to the rank of major general in the U.S. Air Force, and, after retirement, founded The California Institute of Advanced Management with Minglo Shao, a Chinese billionaire who had earlier founded Drucker Academies across China. Others graduated in later cohorts and became senior corporate executives, presidents of colleges and universities, and entrepreneurs. 


Was Drucker Really Different?

Most professors built their careers on conventional research and publication in academic journals. Drucker didn’t. His numerous articles were written for practitioners, not primarily researchers. They appeared in the Harvard Business Review, the Wall Street Journal and other journals read primarily by practitioners. In June 2004, Harvard Business Review honored Drucker  with his seventh McKinsey Award for his article, "What Makes an Effective Executive. 


Drucker’s 39 books were written for practitioners as well. They won and received numerous accolades. Yet Drucker did not write synthetic research typical in academia, where one or more hypotheses based on multiple inputs are tested for significant differences. 


Drucker used a different research model. He declared, “corporations are my laboratories.” His conclusions from observation are the basis of the Drucker Difference. They were explained first by Einstein who used the method and explained it in an article in the London Times.


Drucker’s Research Model

Asked in class where he got his vast knowledge and extensive experience to help organizations in so many different industries, Drucker answered: “I have no vast knowledge nor extensive experience on any specific topic. I have only ignorance and lack of experience. Therefore, all I can do is to ask questions. Clients have the knowledge and experience which I lack; they are the real experts on the topics they hire me for.” 


He then gave examples of his questions, beginning with “What business are you in?” “Who is your customer” “What does your customer value? “What are your objectives” and “What is your plan for getting those results?” 


Other Questions

General Electric’s former CEO Jack Welch, who retired with the largest retirement package ever awarded, significantly increased GE’s wealth. He credited Drucker’s consulting. Welch said that Drucker had asked him two questions: “If you have a choice, which GE businesses would you discard?” and “If this is true, what are you going to do about it?” 


Welch explained that he made the decision to sell or liquidate even profitable GE businesses, which were not number one or two in their markets and were unlikely to attain these positions. He used the funds to invest in businesses with better potential.  Over nine years this increased GE’s wealth by 4000 percent. This became known as Drucker’s Abandonment Theory.


Another former client explained: “Drucker got us thinking through our problems and applying our own knowledge and experience in a way we had never considered previously. This was amazingly effective, and we found solutions to our problems with his guidance that we had overlooked.” 


Drucker was Different 

Here was an expert who not only did not claim special talents but rejected the title “guru.” Drucker made no claim as being an extraordinary management researcher. When not at the university, Drucker used his home as his office. He practiced without a staff or even a secretary. He even answered his own phone. He did not claim any special expertise or experience. Yet he reportedly received as much as $10,000 for a few hours work. Few complained. He taught a simple procedure to students. It began with defining the problem and determining the relevant factors including facts, estimates, speculations, assumptions, time available and financial limitations. Only then did he advise clients to identify, discuss, compare, and analyze possible solutions.


Strategy, not Formulae

Drucker refused to develop strategy by formula. There was no BCG nor GE/McKinsey chart with cash cows or dogs. He believed that each situation was so unique, that a manager must know as much as possible to determine strategy. There was no common element of identical importance for all situations. What was decisive and important in one situation might be totally unimportant in another. 


Decisive elements might not even be quantitative or directly associated with profit. While profitability was deemed as necessary to a business as oxygen to breathing, he said that profit maximization was not, and noted that transistor radios were developed in the U.S., but lost the market to the Japanese because American developers tried to maximize profit. Drucker described management as a liberal art and suggested that liberal arts should be employed in developing strategies and management decisions. He noted economics, ethics, history, humanities, philosophy, social science, physical sciences, and psychology, as all being useful in a variety of managerial and business situations. He noted that in addition to external knowledge, self-knowledge of the organization and its people and available resources might be of even greater importance. 


Drucker also wrote that 50% of the outcome of any project was due to its leadership. Once invited by an organization to explain the latest leadership techniques, he rejected the opportunity with the explanation that the latest techniques were known to the ancients and recommended that his inquirer read “the first systematic book on leadership and still the best” which had been written 2000 years earlier by Xenophon, an ancient Grecian general and author.


Drucker and Research 

Most controversial was Drucker’s approach to research, yet it was also employed by Einstein who’d been a researcher in theoretical physics.


In the single year, 1905, Einstein produced four papers, winning the Nobel Prize for theoretical physics. All four were written a year after earning his PhD at the University of Zurich while he was working at the only job he could obtain: as Assistant Patent Examiner in the Swiss Patent Office in Bern. Like Drucker, he had no conventional laboratory or computers.


The Theory of Relativity

Einstein himself described the development of one of his most famous theories, the Theory of Relativity. He imagined himself traveling along side of a moving beam of light. Einstein may have provided Drucker with ideas of research. Drucker observed people in companies in action as Einstein had observed his imaginary beam of light. He used analysis and development of what he observed to develop his theories of management.


Einstein Reveals His Research Methodology 

Einstein described his research methodology in an article in the London Times in 1919, discussing what he called his “Theories of Principle.” Einstein wrote “these theories employ the analytical, not the synthetic method of research. Their starting-point and foundation are not hypothetical components, but empirically observed general properties of phenomena, principles from which mathematical formulae are deduced of such a kind that they apply to every case which presents itself.” 


Synthetic research is what most use in research. It starts with the known and proceeds to the unknown, beginning with a hypothesis or hypotheses. It then tests these hypotheses by proving or disproving each usually by examination of a sufficient number of examples and testing mathematically for significant differences.  Einstein’s analytical research starts with the unknown and proceeds to the known. There is no hypothesis. One definition of analytical research is “a specific type of research that involves critical thinking skills and the evaluation of facts and information relative to the research being conducted.” This analytical process is how Drucker arrived at his theories and is part of the Drucker difference.


This research approach comes from a simple model:

1.   Observation, either real or even imagined

2.   Analysis of the observation or imagination

3.   Construction of theory based on this analysis 


A sampling of Drucker’s theories derived analytically include:

·      That marketing and selling are not the same. 

·      Moreover, selling is not a subset of marketing and marketing and selling could be adversarial. Since, if the product or strategy chosen by the company were better, with the same effort and ability, the same salesmen might sell more product with less effort.

·      What everyone knows (or think they know) is usually wrong. This short statement was the one most uttered by Drucker in the classroom. 

·      Social Responsibility and Ethics are part of good leadership. 

·      Society demands that an organization be profitable, but not the maximum profit attainable.

·      Many managerial decisions are made from the gut, and these may be optimal despite complex analyses. 

·      Managers must ultimately make decisions from the gut.


What Drucker taught, worked, and the “Drucker Difference” produced many successful leaders using “Drucker Difference” skills. While other factors influence results and other research methods are still valuable, researchers using primary analytical research including Einstein confirm the value of the “Drucker Difference” confirming Drucker’s conclusion that Management is a Liberal Art.

Peter Drucker escribió extensamente sobre las funciones y responsabilidades de los gerentes y sobre los principios que podrían ayudar a mejorar el desempeño organizacional. En sus obras, Drucker infiere que los individuos que conforman la organización deben cultivar el autoconocimiento, la autoconciencia y desarrollar sus habilidades a través de la aplicación. Aprendemos por primera vez sobre el concepto de la gestión como arte liberal en el libro de Drucker, "The New Realities". En este texto, Drucker se refiere a la gestión como arte liberal: "La gestión es, por lo tanto, lo que la tradición solía llamar un arte liberal - 'liberal' porque trata con los fundamentos del conocimiento, el autoconocimiento, la sabiduría y el liderazgo; 'arte' porque trata con la práctica y la aplicación. Los gerentes recurren a todos los conocimientos e ideas de las humanidades y las ciencias sociales - en la psicología y la filosofía, en la economía y la historia, en las ciencias físicas y la ética. Pero deben enfocar este conocimiento en la efectividad y los resultados." (Drucker, 1989) Drucker argumentó que debemos reconocer que la naturaleza humana es imperfecta, pero que, a través de la observación y la contemplación, y mucha, mucha práctica, la toma de decisiones puede mejorarse. Con el tiempo, a medida que las personas practican la gestión de manera ética y responsable, la comunidad en general se beneficia de las decisiones tomadas en organizaciones responsables y socialmente conscientes. La gestión como arte liberal es un concepto que caracteriza una filosofía, una que se basa en los elementos del conocimiento, el autoconocimiento, la sabiduría y el liderazgo. Esta filosofía implica que cualquier individuo tiene el potencial de crecer y desarrollarse, y convertirse en un gerente efectivo, siempre y cuando este individuo se tome el tiempo para reflexionar, desarrollar habilidades y conocimientos, y adquirir continuamente experiencias que enriquecerán su perspectiva sobre cómo liderar eficazmente a otras personas. Sin embargo, Drucker reconoció que el interés propio interrumpe y, en los peores casos, impide y restringe los esfuerzos de los demás. Como tal, el gerente debe desarrollar la capacidad de observar lo que está ocurriendo dentro y fuera de la organización. Al mismo tiempo, la persona debe desarrollar la autoconciencia y la capacidad de reflexionar sobre su propio comportamiento y las decisiones que toma. Esto incluye analizar cómo las decisiones pueden influir en las acciones y el comportamiento de los demás. Es a través de la autorreflexión y la conciencia que podemos notar lo que ha funcionado, lo que no y lo que podríamos hacer de manera diferente la próxima vez que surja otra situación. Un gerente puede desarrollar inteligencia emocional, utilizando el concepto de Daniel Goleman. Y en el contexto de la gestión como arte liberal, esto es lo que llamaríamos autoconocimiento. Un gerente puede volverse más efectivo y llegar a apoyar el crecimiento y desarrollo de los demás, siempre que aprenda a valorar a las personas por quienes son, y les permita espacio para ser ellos mismos. Pero para hacer esto, el gerente debe aprender a escuchar a los demás, respetarlos y reconocer sus preocupaciones y necesidades. También es importante aprovechar las ideas y sugerencias de las personas para ayudar a encontrar soluciones. Esta es un axioma importante dentro de la gestión como arte liberal. Otro elemento clave de la gestión como arte liberal es la noción de que el individuo debe construir conocimiento. Como tal, la persona debe buscar activamente información, datos, hechos e historias que puedan ayudar a aumentar el conocimiento. Además, podemos mejorar nuestras habilidades gerenciales y decisiones aplicando una perspectiva transdisciplinaria para resolver problemas. La perspectiva transdisciplinaria proporciona al individuo una visión integrada y más holística que combina diferentes puntos de vista de las artes, las humanidades y la ciencia. Drucker postuló que podemos aprender leyendo historia, filosofía y economía, y que la reconciliación de ideas de múltiples disciplinas puede ser beneficiosa para determinar el mejor curso de acción. Drucker sugirió que la consideración cuidadosa de diferentes alternativas y efectos posteriores, contingencias y resultados potenciales, mejoraría las decisiones y permitiría que el individuo se convierta en un tomador de decisiones más efectivo. Según la gestión como arte liberal, es importante que consideremos cómo nuestras acciones influirán en los demás y que asumamos la responsabilidad de nuestras acciones. La gestión como arte liberal postula que las personas se definen a sí mismas (y sirven a la sociedad) a través de la acción responsable. Esto significa que los gerentes efectivos actuarán de manera responsable y con ética, y utilizarán su estatus y poder para promover el bienestar de la organización y su gente. Esto infiere que el individuo actuará con el mejor interés de la organización (y sus partes interesadas) en mente. Actuar con buen juicio, tener lucidez y una mejor comprensión de las situaciones y contextos es lo que llamaríamos ejercer la sabiduría. Para involucrar a las personas y construir mejores organizaciones, y en última instancia contribuir a lo que Drucker llamó una "sociedad funcional", es vital que tratemos a todas las personas dentro de la organización con respeto y dignidad. Y que ayudemos a las personas a crecer y desarrollarse y a encontrar significado en lo que hacen. Así es como se construyen las grandes organizaciones. Esto es lo que llamaríamos liderazgo. Y los líderes dentro de la organización deben ser conscientes de que el mundo evoluciona y que algunas cosas deben cambiar, mientras que otras deben mantenerse. Esto significa equilibrar el cambio y la continuidad y reconocer qué proceso o actividad necesita ser renovado, y cuál otra práctica necesita ser preservada.  La gestión como arte liberal está arraigada en la práctica y la aplicación, en la autorreflexión, en tratar a las personas con dignidad y respeto, y en usar un lente transdisciplinario para ayudar a mejorar las decisiones. Se necesita tiempo para lograr resultados y construir grandes organizaciones. Pero se puede lograr. Y las organizaciones cuyos gerentes pueden practicar y aplicar, y reflexionar y aprender continuamente de sus acciones, tienen más probabilidades de ayudar a construir una mejor comunidad y una sociedad funcional y próspera.

“What does ‘Capitalism’ mean when Knowledge governs – rather than Money? And what do ‘Free Markets’ mean when knowledge workers – and no one else can ‘own’ knowledge – are the true assets?” (Peter Drucker, 1999). This issue of my newsletter focuses on features of today’s knowledge work, and what knowledge work might look like in the future. In part one, I discussed some of the challenges associated with measuring knowledge worker productivity. In this installment, I’ll take up Drucker’s concept of “Post-Capitalist Society” and what it might mean for knowledge work in the 21st century. Fear not; this will not be an academic treatise on Marx or Marxism. But central to an understanding of our knowledge-based society is some sense of how previous industrial society was configured and structured. As I argued in the last installment of this newsletter, part of our difficulty with measuring knowledge worker productivity is that we still use the language of industrial capitalism: we measure productivity in terms of output, particularly in quantity. We lack a more modern understanding of what productivity looks like. Why? Marx and Capitalism Marx saw capitalism as a stage in history, as part of a larger pageant of human conflict. In The German Ideology (1845), Marx critiques the idealism of German philosophy as locked in the realm of thought instead of material reality. It is time, he argues, for German philosophers to stop simply criticizing each other regarding implications of spiritual matters (the nature of knowledge, etc.) but rather to address the realities of material life. Marx was reacting to the decline of Hegelian thought, and transformed Hegel’s spiritual dialectic model into dialectical materialism. For Hegel, human development was a process of conflict at the spiritual level, when human understanding is challenged by contradicting experiences and events, leading to a new level of awareness, all guided by “Geist”. Marx took this out of the spiritual realm and grounded it in worldly events; his dialectic model was still one of human transformation and development, but it morphed into a model of class conflict. Dialectical materialism involved observable conflicts in social conditions and economic status that would then be acted upon to create a new social order. Like Drucker, Marx was a social theorist, and was reacting to the dramatic changes he saw happening in his time. Marx and his associate Engels observed the transformation from a rural to an industrial society and the associated social upheavals. Marx and Engels focused on the shift from an economy where value was derived from labor to one that relied on machines and money (capital) to produce the material needs of human beings. The culmination of their efforts was Marx’s massive work, The Capital (Das Kapital), published in three volumes in 1867, 1884, and 1894. The work is an intricate analysis of capitalism as an economic system as well as a social structure. There is no substitute for actually reading the text, but, for our purposes here, Marx had several key points that are germane to our discussion of today’s knowledge society: 1. Labor theory of value : Marx challenged utilitarian viewpoints of value, stating that the value of products lies not in their satisfaction of human wants, but in the human labor used to produce them. Value is in production, not in the end-user’s perception of value. 2. Ownership of means of production : In earlier rural societies (at least those with free labor), labor owned the means of production (its own work). Under capitalism, a ruling class owned the machinery and financial instruments (the capital) necessary to production. They also, in fact, own the labor, as workers no longer have a say in their hours, working conditions, etc. Owners derive unearned income from the labor of workers who are under their control. 3. Alienation: The process of industrial production involves an increasing deskilling of work, meaning workers have less of an association with the larger purpose of the process or output. As labor is divided into more specialized functions, there is increased alienation. 4. Dialectical materialism : As capitalism increases social conflict (class conflict), it sows the seeds of its own demise. It is part of Marx’s historical theory of capitalism as one stage in human development. Eventually, socialism will replace capitalism, and workers will own the means of production, ushering in a new social order. Post-Capitalist Society In 1993, Drucker published Post-Capitalist Society, a book that advances a bold argument about Marx’s theories and the trajectories of history. It was one of his more successful books, and I think he left us with much to think about as we navigate the waters of the new or next knowledge society. Drucker looks back on Marx’s evaluation of capitalism with an historical view, much like Marx looked at Hegelian and other assessments of society in his time. In this sense, Drucker follows in the tradition of European theorists critiquing the ideas of the past, using an historical argument. According to Drucker, the manufacturing economy framed the conversation around society, economics, and politics from the late 1800s to the 1950s. Marx’s labor theory of value dominated discussions, as workers competed to have equal power and voice with owners (capitalists). However, as Drucker argues, the owners of capital (the financial titans of industry) peaked by the First World War, and were replaced by professional managers by the 1950s. The classic dialectic between labor and capital was no longer relevant by the 1950s, as “capitalists” no longer existed. Drucker posits that by the 1970s, “capital” would be in the hands of the workers themselves in the form of pensions, mutual funds, and other collective methods of corporate ownership. According to Drucker, the factors of production were no longer labor or capital, but knowledge by the mid-20thcentury. Knowledge workers owned the capital (pension funds, and later 401ks) and also owned the means/tools of production (knowledge). This perspective upended not only traditional notions of capitalism as viewing labor and capital as the primary inputs for production, but also upset the social order. Moreover, we faced a new economic challenge of measuring productivity in a new way (related to knowledge) but also a social challenge as the old service (manual labor) workers would be left behind. Furthermore, we would face a dichotomy between intellectuals and managers. Both of these conflicts are akin to what Marx alluded to in his reference to dialectical materialism. In essence, while highly critical of Marx, Drucker used a version of Marxist theory to postulate the existence of a “post-capitalist society.” Drucker was no fan of Marx but uses an historical argument and similar language about analysis of inputs (labor and capital, but in Drucker’s case, knowledge). The difference is that Drucker is not engaging in a dialectical process (and not one focused on material concerns alone). According to Drucker, one of the primary reasons that Marx’s worldwide proletarian revolution failed to materialize was the inadequacy of his model of “economic man” (his sole emphasis on material satisfaction as an indicator of society’s wellbeing). Drucker rejected this model of society, arguing for an industrial model of society where the manufacturing plant community provided meaning to the worker. Crucial to defeating the forces of totalitarianism (and Marxism, for that matter) was providing individuals in society with status and function . Status gives people a place in the social structure, whereas function provides individuals with a purpose. Economic meaning was not enough; people needed this larger sense of individual and community meaning. In the early twentieth century, because of the incredible gains in manufacturing productivity, capitalism emerged as the dominant system. However, as society moved away from industrial employment towards knowledge work, this new post-capitalist society presented new challenges – including the possibility for social disorder. Thus, Drucker turned to understanding the “ knowledge society ”, a new stage in human development. According to his analysis, what were the new challenges inherent in this new knowledge society? As we saw in the previous installment of this issue, knowledge worker productivity and its measurement represented one such challenge – one we still face. Drucker also wrestled with questions of worker motivation, social disorder, and compensation disparities. In our next installment, we’ll expand on Drucker’s concerns and see how they might help us understand where we are with our current knowledge society and the challenges we face.

One cannot manage change. One can only be ahead of it…In a period of upheavals, such as the one we are living in, change is the norm. To be sure, it is painful and risky, and above all, it requires a great deal of very hard work. But unless it is seen as the task of the organization to lead change, the organization…will not survive. Peter Drucker in Management Challenges for the 21 st Century (2001) Alan George Lafley was the CEO of Proctor and Gamble (P&G) from 2000 to 2010 and 2013 to 2016. The Proctor and Gamble Company is a consumer goods corporation headquartered in Cincinnati, Ohio. It was founded in 1837. Today, Proctor and Gamble is healthy and is ranked 55 th in the Forbes Global 2000. In 2000, just before Lafley was appointed CEO, P&G stock dropped by almost 30% in one day, and the next week, it dropped another 11%. P&G lost $85 billion in market capitalization a few months later. Lafley described it as a crisis of confidence; inside the organization, employees were blaming each other, and outside the organization, market analysts and investors were surprised and angry. Retirees were angry over losing half of their profit-sharing nest eggs. The news media used headlines such as “P and G Investor Confidence Shot”, “Trouble in Brand City,” and “Does P&G Still Matter?” It appeared that a major, almost 200-year-old company, was in danger of going out of business. Fortunately, Lafley had the advantage of being familiar with Peter Drucker’s writings and was able to talk with him in person. What follows is an accounting of Lafley's actions using his own experience (P&G was his first CEO job) along with Peter Drucker’s writing and personal advice on sustainability. · One of Drucker’s last works was answering the question, “What is the work of the CEO?” Lafley realized that the CEO is singularly held accountable for the performance and results of the company and acted accordingly. · Trust is needed for sustainability. Trust at P&G had evolved to mean that employees could rely on the company for lifetime jobs. Lafley redefined it as consumers’ trust in the company’s brands and shareholders’ trust in its value as a long-term investment. · The consumer is boss. This mindset was emphasized to all employees. Another more famous Drucker Quote is, “The purpose of a business is to create a customer.” Lafley turned around the company-wide habit of losing touch with customers by emphasizing employees at all levels getting closer to customers. · Lafley listened to Drucker that a company must decide what business you are in (or not in). Lafley took the advice and after careful analysis caused P&G to keep some products and businesses, eliminate some products and businesses, and add some products and businesses. This was also the advice Drucker gave to Jack Welch, General Electric CEO, a few years earlier about streamlining the company by focusing on where to compete and where not to compete. Lafley expanded Drucker’s advice by adding his own statement on sustainability; “We must work on the present to earn the right to invest in the future.” · As published in the Wall Street Journal in January 2005 (The American CEO) Drucker observed that we don’t completely understand the unique role of the CEO; What is the work that only they can do and that they must do? The CEO has the power and the ultimate responsibility for business sustainability. The CEO is the link between the inside of the organization and the outside of the organization. He or she alone experiences the meaningful “outside” the organization and is responsible for understanding it, interpreting it, advocating for it, and presenting it in a way that enables sustainable sales, profit, and total shareholder return. For Lafley, “meaningful outside” can include several stakeholder classes, but it emphasizes the idea that the “Consumer is Boss.” Lafely saw that over the years, P&G employees had been drawn to internal interests, and inward focus is the enemy of growth. It is the CEO’s job to deal with outside stakeholders and have a deep understanding of their competing interests, as well as how those interests correspond with the capabilities and limitations of the organization. And Lafley went to work on reinvigorating focus on “outside the organization stakeholders” while keeping in mind that employees are a company’s most valuable asset. Strengthening relationships with analysts and investors resulted in a better understanding of their wants and needs. · Drucker said that effective CEOs make sure that the performing people are allocated to opportunities, rather than only problems. Lafley took this advice to heart and also reiterated the importance of succession planning. · Avoiding complacency in an organization is a must. The CEO should always ask, “Are we winning with those who matter most and against the very best?” The CEO should ensure that the company’s values, purpose, and standards stay relevant for the present and the future and for the businesses the company is in. CODA When looking at overall company sustainability, the difference in governance between Jack Welch of General Electric and A.G. Lafley of Proctor and Gamble is dramatic This is a potential subject for further research on sustainability. In the leadership literature Lafley is generally rated as a hands-on people person who consistently strived to develop leadership in his employees. He was respectful of employees and valued listening to them. He could be described as a servant leader or a follower of Peter Drucker’s management as a liberal art leadership style. Welch was very competitive and was also described as having a combative and aggressive personality. He stressed shareholder value and the absolute necessity of financial performance. In the name of cost-cutting, he would occasionally order massive layoffs, which caused employee resentment and mistrust. His mantra of “Win at Any Cost” has been said to damage the ethical behavior of employees. When Lafley and Welch were CEOs of their respective companies, the companies thrived. When Welch left GE in 2001 the company had “disappointing results for 2 decades.” When Lafley left P&G in 2016 the company continued to thrive and is still highly rated. Bibliography Silva, A. 2015.
