From Self-Mastery to Enterprise Leadership: 99 Drucker Principles for the Evolving Manager
Peter F. Drucker’s foundational work defines management not merely as a set of techniques for achieving efficiency, but as the specific organ of modern institutions and the leadership group of a society dependent on organizations. Drucker’s insights guide the executive through a necessary career evolution, progressing from managing personal effectiveness to leading subordinates, and finally to mastering the complexities of the overall enterprise.
This detailed paper synthesizes 99 core pieces of Drucker's advice, charting the essential principles required for success across the three critical stages of a managerial career: Manager of Self, Manager of Others, and Manager of Managers.
Stage I: Manager of Self (MOS) – The Foundation of Personal Effectiveness (33 Advises)
The first step in management is self-management, as managing others is "iffy," but one can always manage oneself. Personal performance, integrity, and career planning are the core pillars of this stage.
Personal Performance and Mindset
- Always manage oneself, or at least try, recognizing that this is the primary area where success is within individual control.
- Understand that management is most effectively done by example, not by preaching or policy, as associates will do as the boss does.
- Commit to continuous learning and self-development, using organized feedback to improve performance.
- Focus on making one’s strengths productive, avoiding the futile attempt to build primarily upon weaknesses.
- Ensure personal integrity of character is the single required quality a manager must bring to the job, as it cannot be learned and is essential for developing others.
- Ask: "How can I, and we in my organization, use this idea or these insights to perform more effectively?".
- Recognize that information is the manager’s main tool and capital.
- Define the information you need yourself; do not leave this critical task to the mythical "information specialist".
- Be workaholic, expecting work to be challenging and demanding, particularly as a young professional.
- View the organization employing you as your tool to achieve your own ends in life and work.
Ethics and Prudence
- Practice the Ethics of Prudence: shun actions that cannot easily be understood, explained, or justified.
- Accept that the leader's primary ethical obligation is to give the example of right behavior.
- Seek self-fulfillment through self-discipline and self-respect, striving to become the "superior man" rather than accepting mediocrity.
- Ensure that any decision or action is sound in expediency (short-term) as well as in long-range objective and principle.
- If faced with an ethical conflict, remember the professional's first responsibility: primum non nocere ("Above all, not knowingly to do harm").
Work, Time, and Career Planning
- Learn to organize and express ideas in writing and speaking, as the written or spoken word is the only tool managers have to motivate and guide people.
- Organize time well by planning and thinking before acting, focusing on thinking through the areas where objectives should be set.
- Spend time thinking through the boss’s problems and how to contribute to the success of the superior, considering this a part of the manager's job.
- If you are a young manager, accept that continued self-development and advanced education are necessary to stand out in the crowded market.
- If you are starting out, decide early if you thrive in secure routine work or prefer work challenging the imagination and ingenuity.
- Determine if you belong in a large organization (policies/channels, remote effectiveness) or a small one (personal contacts, immediate effectiveness).
- Choose deliberately whether to start at the bottom of the hierarchy or in a staff position near the top (which offers exposure to top deliberations but is inherently insecure).
- If aiming for rapid promotion, recognize the demographic pressures and the need to be "near the top" by age thirty-five.
- Be realistic about compensation: always take a raise in lieu of a promotion, but never the reverse, as genuine promotion includes higher pay.
- Develop a major outside interest to ensure maturity, effectiveness, and resistance against the setbacks inherent in any career.
- If a job proves too small to challenge and test your abilities, recognize that this will quench your "fire" and lead to decline; redesign the job or be prepared to leave.
- When preparing for career continuation (e.g., prior to mandatory retirement at 65), start preparation at least six months, but rarely more than one year, in advance.
- Be open to a second career change in your mid-forties, when pension is usually vested and you know what you are good at.
- As a knowledge worker, understand that you are paid for putting knowledge to work, requiring you to think through and review your contributions rather than focusing solely on effort.
- As a knowledge worker, recognize that you must be able to do your own planning; separation of planning from doing is inappropriate for knowledge work.
- If you are a career professional, focus on making your output (ideas and information) the effective input for othersby avoiding specialized jargon.
- As a career professional, accept the role of "teacher" and "educator" for management, helping to raise the organization's vision and standards within your area of expertise.
- Understand that the knowledge worker will not produce if managed under Theory X (coercion), as knowledge must be self-directed and requires responsibility.
Stage II: Manager of Others (MOO) – Leading Teams and Knowledge Workers (30 Advises)
The shift to managing others requires translating personal integrity into institutional design, focusing on objectives, and maximizing the productivity of human resources.
Setting Objectives and Motivation
- Set clear, specific, spelled-out objectives for each subordinate, defining the performance their unit is supposed to produce.
- Ensure objectives spell out the contribution the subordinate unit is expected to make to help other units obtain their objectives.
- Ensure managerial results are measured by the contribution they make to the success of the whole enterprise.
- Counteract functional specialization by demanding that workmanship be made the means to the end of business performance, not an end in itself.
- Avoid management by "crisis" and "drives," recognizing this method is ineffective, misdirects effort, and is an admission of incompetence.
- When setting objectives, balance tangible business goals with intangible goals (e.g., manager development, worker performance, public responsibility).
- Recognize that the fundamental task in motivation is to substitute management by self-control for management by domination.
- Do not use measurements to control people from outside and above; this violates the principle of self-control and is an abuse.
- Supply managers with clear and common yardsticks in all key areas of the business.
- Ensure information needed for self-measurement goes directly to the subordinate, and is not used solely as a tool of control from above.
- Structure management so that subordinates focus on the job demands, not on interpreting the boss’s casual remarks or assumed behaviors.
- Implement a formal review process (like the "manager’s letter") where subordinates define their job objectives and list what helps or hampers their performance.
Managing Knowledge Workers and Teams
- Ask knowledge workers directly: "What do I... do that helps you in doing what you are being paid for? … What do we do that hampers you?".
- Enable knowledge workers to do what they are being paid for by minimizing paperwork and pointless demands on their time.
- Systematically conduct an inventory and ranking of major opportunities; then ensure performing people are assigned where the results are, not where organizational demands dictate.
- Recognize that motivation and communication require primarily social skill (integration and synthesis) and adherence to the principle of justice.
- Foster the understanding that workers want achievement and responsibility (Theory Y), but structure is needed to provide the security of order and direction.
- Avoid relying on fear ("the stick") to motivate, as it has lost coercive power in developed countries and causes only resentment.
- Use material rewards ("the carrot") cautiously; exclusive reliance on them is self-defeating due to increasing costs and toxic side effects (dissatisfaction over relative pay).
- Recognize that a manager must be a "fellow employee" and a superior, lacking the coercive authority of a traditional "master".
- Build a team by harmonizing the three major functions of the enterprise: managing a business, managing managers, and managing worker and work.
- Ensure managers are willing to listen to subordinates; mutual understanding results from "communications up".
Staffing and Development
- When selecting people, always maximize strength rather than trying to minimize weakness.
- If a job proves inadequate (defeats two or three successful candidates consecutively), redesign the job, assuming it is "unfit for human beings".
- Remove any manager who consistently fails to perform with high distinction, as retaining them is grossly unfair and corrupts the organization.
- Accept that star individual contributors (e.g., salespersons, researchers) may earn more money than their unit manager, as performance compensation is crucial in specialized fields.
- Understand that developing people is a specific basic operation of management, requiring the manager to strengthen integrity and direct subordinates’ growth.
- Recognize that promoting people who are incompetent to manage, solely for reward, is destructive to the organization.
- Avoid organizational chaos by keeping the middle ranks lean, sanctioning new activities only if old ones are cut back.
- Be prepared to be a human contact, a guide, and a listener for young employees during their first ten years, as the absence of this support causes high turnover.
Stage III: Manager of Managers (MOM) – Leading the Enterprise (36 Advises)
In this stage, the executive is responsible for the overall structure, strategy, and continuity of the institution, often operating as part of top management.
Strategy and Performance Measurement
- Measure the performance of today’s management primarily by its ability to prepare the business for the future.
- Implement managerial yardsticks in four crucial areas of decision making: capital allocation, people decisions, innovation, and strategic planning.
- Organize feedback from capital investments to measure results against expectations, ensuring integrity to face up to actual results.
- Measure business planning performance by assessing whether predicted events happened and if the goals set were the right ones in light of actual developments.
- Recognize that profit is not the purpose of business, but a limiting factor and the test of the validity of business decisions.
- Set objectives in all eight key areas essential for survival: marketing, innovation, human organization, financial resources, physical resources, productivity, social responsibility, and profit requirements.
- Define the specific work and assignments of the Board of Directors before discussing its composition.
- Require the Board to ensure that top management designs adequate performance yardsticks for itself.
- Ensure the board addresses what business the company should not be in, and what should be abandoned to keep the organization "lean and muscular".
Organizational Design and Structure
- Keep management levels to the absolute minimum, as every added layer in the chain of command distorts objectives, communication, and management development.
- When designing the organization, start by analyzing the key activities where excellence is required or where lack of performance would endanger survival.
- Design the organization so that it imposes the smallest possible number of relationships on any given activity, while ensuring crucial relationships are easy and accessible.
- Ensure managers are placed high enough to have the authority needed for typical decisions, but low enough to retain detailed, firsthand knowledge of the action.
- When designing the knowledge organization, clearly spell out decision authority (who can change the plan, and who can change the changers), recognizing the need for greater devolution of power.
- For new middle management structures, focus on responsibility and contribution rather than traditional downward authority.
- Clearly separate "Conscience" activities (vision, standard setting, auditing) from operating and advice-giving activities.
- When organizing specialized advisory or teaching staff, require them to operate as service institutions by setting objectives and measuring results.
- In an innovative organization, organize work from where the company wants to be (the future) back to what must be done now, rather than extending the existing business.
Innovation, Growth, and Financial Management
- Treat innovation efforts distinctly; assume the majority will fail, and calculate potential results to be at least three times the needed company objectives.
- Separate the financing and control of innovation from ongoing businesses until the innovation is successfully established.
- Create an innovative organizational culture by encouraging even junior personnel to bring "wild" ideas to top management for funding and support.
- Set a growth goal determined by the minimum growth needed to avoid becoming marginal as the market expands.
- Distinguish between desirable growth (strength leading to productivity) and undesirable growth ("fat" or "malignant tumor" purchased at the expense of productivity).
- Base a growth strategy on concentration, centering on specific strengths and targets of opportunity created by anticipating changes.
- When growing a small- or medium-sized business, anticipate financial structures and resources needed at least two to three years ahead.
- Manage the business to satisfy two incompatible requirements during inflation: minimum exposure to loss(minimum cash/maximum short-term debt) and high liquidity (crisis readiness).
- Understand the distinction between "producing capital" (fixed assets) and "supporting capital" (working capital), and manage the productivity of each differently.
Leadership Development and External Role
- Ensure that top management is developed well ahead of time (approximately five years) to meet the demands of future growth.
- Ensure top management has thought through the succession to top management jobs.
- Utilize mandatory retirement (e.g., at age 65) as an opportunity for "career continuation" in advisory or project roles, leveraging the senior executive's skills for the company's benefit.
- Recognize that top management’s decisive function is political leadership, not merely administration.
- Prepare the organization to handle the information explosion by defining who shall have access to what information, following the rule that a manager needs to know everything that pertains to their work and the level immediately above them.
- Manage social impacts and social responsibilities by thinking through the role, setting objectives, and performing; avoid treating them merely as public relations issues.
- For non-profit institutions, the most essential step is defining what their task is and what it should not be, in order to make them manageable and performing.
- Work toward making the elimination of negative social impacts (e.g., pollution) into a profitable business opportunity.
- Do not risk the performance capacity of the enterprise by overloading it with social responsibilities that create excessive social overhead costs.
Analogy for Managerial Evolution:
The progression of a manager through these three stages is like developing a complex instrument. First, the individual must achieve Manager of Self, ensuring the instrument is well-tuned and structurally sound (mastering personal ethics, strengths, and time). Next, as Manager of Others, they learn to conduct a small ensemble, translating the instrument's capabilities into coordinated output (setting objectives, motivating teams, coaching knowledge workers). Finally, as Manager of Managers, they must master the orchestration of the entire symphony, designing the concert hall itself (organizational structure), selecting the music (strategy), and ensuring the performance serves the wider community (managing social impacts and securing the future).
