Challenging Tasks Create Capable Managers
Since 2022, four experts from Hyundai Motor Group and external organizations have gathered online every Monday at 7:00 AM for two hours to read and discuss Peter Drucker’s Management. Deep insights are shared as each participant’s field experience and perspectives converge.
This post summarizes the reflections shared during the reading sessions held on September 29 and October 20, 2025, regarding Chapter 32: Design and Content of Managerial Jobs.
Introduction
While we previously explored the reason for a manager’s existence and their essential qualities, this session focused on how to actually design managerial work. Does a detailed Job Description (JD) truly create a great manager? How should control over a manager be exercised? We sought answers to these fundamental questions.
Key takeaways from the Chapter: Debunking Myths about Managerial Jobs
1. Myth: “A leader’s role is to move away from practical work and only ‘manage.’”
Drucker defines a job that only performs administrative tasks (supporting subordinates, coordination, etc.) as a “non-job” with no substance. Administrative tasks usually take up only a small fraction of working hours. A leader who focuses solely on management risks becoming an “organizational obstructer” who interferes with the autonomy of subordinates or creates unnecessary meetings. Therefore, a manager must have their own “Specific Task” for which they are solely responsible. A leader establishes true authority only as a “Working Boss” who maintains expertise in the field.
2. Myth: “Jobs should be specified into small, clear pieces to prevent failure.”
Designing narrow jobs to reduce failure is a way to kill talent. Jobs that are too small lead to complacency, resistance to change, and a loss of growth opportunities. A job should be designed large enough to be “challenging and burdensome” for one person. An organization must provide a “Big Job”—a vast playground where employees can test their limits and grow over several years. This is especially critical for managerial roles.
3. Myth: “Managers function within the authority and responsibility given to them.”
Drucker argues that managerial authority is not a gift granted by a supervisor, but a tool arising from the “objective necessity” of the job. Decisions required to produce results—especially those a superior cannot make from a distance—inherently belong to the front-line position.
Rather than requiring permission for every action, organizations should only define “what must not be done” (e.g., budget limits or core policies). Beyond these few boundaries, managers should have full autonomy to decide and execute under their own responsibility and self-control.
Discussion: Beyond the Controlled Manager, What is the Work of a Self-Managing Leader?
How Twenty-Year-Olds Managed a Continent
The most powerful tool for developing managers is the job itself. In the late 19th century, the administration of India was led by fewer than 1,000 young men in their early twenties. Drucker attributes their ability to manage a vast subcontinent to the fact that they were given “real work”—jobs with immense responsibility and substantive authority. In contrast, many modern managers become passive bureaucrats within narrow job scopes. The core task of an organization is to make leaders perceive themselves as managers who exercise “self-control” without detailed interference from headquarters.
The “Not-To-Do” List and Self-control
The success of autonomous management depends on “Self-control,” running toward performance goals rather than reacting to external surveillance. When a leader spends more time on reports to superiors than on field judgment, they eventually fall into the trap of “trained incapacity,” giving up on making decisions and passing responsibility upward. To break this cycle, top management must show trust by delegating full authority, specifying only the “Not-To-Do” list—the absolute prohibitions—rather than a list of tasks.
From a Coordinator to a “Working Boss”
As leaders rise in rank, they often distance themselves from practical work. However, Drucker warns against becoming a “mere supervisor” who depends solely on the output of others. A true manager must be a “Working Boss” with specific tasks that contribute directly to organizational performance. Substantive value is created only when a leader remains connected to the operational field.
A vice president at a leading Korean advertising agency exemplifies this. Despite his high rank, he maintains his “field sense” by personally executing one or two projects annually. This hands-on approach prevents a reliance on outdated experiences and allows him to provide fresh, “eye-opening” perspectives.
Ultimately, when a leader balances management with practical expertise, they earn genuine trust. A healthy leadership culture—where autonomy and expertise coexist—is realized when a leader moves beyond mere coordination to sharing direct insights and running alongside the team.
Closing: Ultimately, Management is Self-Management through the ‘Manager’s Letter’
Are our leaders trapped in a “small birdcage” of reporting and figures? As Drucker noted, job design determines whether an ordinary person becomes a giant or a remarkable person withers into mediocrity.
True autonomous management begins with how a leader defines themselves. To practice this, we propose Drucker’s “Manager’s Letter”—a proactive “job commitment” rather than a passive report. This letter justifies a leader’s existence by clearly defining:
- The organization’s goals as the leader understands them.
- Self-set performance standards to achieve those goals.
- Obstacles that must be removed for success.
Through this “Manager’s Letter,” a leader declares their contribution and reaches a firm agreement with their superior. This process restores a “view toward the top,” shifting focus from narrow departmental interests to the success of the entire enterprise. When mutual trust replaces coercive control, a leader finally stops waiting for instructions and begins to act as a truly self-managing subject.
