[Yoon Eun Key's X Management(65)] Why Is Dividing Management Important? T...

[Columnist Yoon Eun Key, Korea Lecturer News] Recently, I had an in-depth discussion on the topic of 'The Evolution of Modern Management' with Professor Cho Dong-sung, a giant in the field of business administration.

As emphasized in my recent book ‘X Management’, we deeply resonated with the idea that we have moved beyond the era of "addition (+)," where resources are simply input to produce results, and have entered the era of "multiplication," where diverse capabilities are fused to generate explosive synergy. We also agreed that multiplying by zero (0) or minus (-) can lead to extreme risk. Since multiplication is paired with "ninugi" (dividing), we also agreed that a portion of massive achievements must be shared with society.

However, befitting a master of management, Professor Cho explained that for the completion of 'X Management,' "dividing must be linked not only to distribution and social contribution but also to management significance and principles." The AI ​​era is an era of 'multiplication management' that generates super-performance. However, merely repeating multiplication inevitably leads to super-risk. Why must we focus on the essence of 'dividing' in the era of multiplication management?

First, division is not 'splitting,' but a process of reaching the 'essence.'

In mathematics, differentiation is the process of breaking a function down into smaller parts to find the slope at that moment—that is, the essence of the change. Division in management is similar. As a company grows, the organization becomes bloated and processes become more complex. At this point, what is needed for a manager is the ability to break down the phenomenon into smaller parts to eliminate unnecessary noise and reach the essence known as the fundamental reason for the company's existence: 'core competency.'

Second is the re-establishment of identity through abandonment.

Professor Cho Dong-sung interprets division as "the act of excluding the unnecessary." If multiplication management expands the scope through the combination of heterogeneous elements, division management is the process of removing from the expanded results what is not our own unique value. Deciding "what not to do" rather than "what to do" constitutes a higher-level management strategy. When purity is enhanced through division, a company's identity becomes clearer.

Third, it is sharing and distribution for a sustainable ecosystem.

From a management perspective, sharing is also the principle of 'sharing' and 'distribution.' Without an answer to how to share the initial achievements generated by 'X Management' with partners, customers, and society, such growth is nothing more than a house built on sand. True sharing management is a future-oriented investment process that divides the fruits of performance and sows them as seeds for future growth. Social responsibility and contribution that go beyond CSV or ESG are essential.

Fourth, in the age of AI, sharing is the wisdom of finding the uniquely human 'Why'.

We live in an era where AI processes the 'How' of all data through a multiplicative method. The task remaining for human leaders is to answer the fundamental question, "Why are we doing this?" This is also why philosophy is once again in the spotlight in the age of AI. The wisdom of division—dividing and analyzing issues amidst a flood of information to extract the most valuable 'essential elements'—is a uniquely human domain that AI cannot imitate.

After multiplying, always start anew through division.

If Multiplication Management (X Management) is the engine that expands the scope with powerful driving force, then Dividing Management is like the rudder that precisely adjusts the direction and strengthens the internal foundation. If you have grown your 'body' through convergence, you must now clear your 'mind' through division.

This conversation with Professor Cho Dong-sung awakened the wisdom of combining the fundamental insight of "sharing" with the methodology of "X Management." With the advent of the AI ​​era, many people are engrossed solely in generating initial results. Who are the true winners? They are not merely those who produce initial results, but leaders who know how to discover the most essential values ​​through sharing and share those results. Isn't this the principle of the universe and the providence of the Creator?

“Addition is paired with subtraction, and multiplication is paired with division.”
