Giving an example of showing the effectiveness of the universal Principle, here we focus on “The Principle of Method”.

The Principle of Method asks the fundamental question “What is a method?” It attempts to make the essence of all methods clear. It sets out the most important points found in all methods without exception pursuing universality. In this context “Essence” means the key points particular to each case. “Principle” means a general definition including essences relevant to all cases.

In the “method” case, the Principle of Method is defined as “a procedure able to achieve its objective in specific circumstances”. We inevitably use method in certain circumstances. Besides we call the way that we accomplish our objective, “method”. In other words, according to the Principle of Method, “the effectiveness of a method depends on two points: the objective and situation”. We cannot judge the value of a method without also considering the objective and the situation.

You may think that the Principle of Method is obvious, but most leaders and organizations are not conscious of it they therefore tend to follow precedents. Therefore even great Executives, presidents, and managers lose sight of their original missions to increase their benefit. The international financial crisis is a typical example.

Most people think they know “methods”, but they don’t understand “Essence of Method”, so they can’t utilize methods effectively and flexibly. Generally, we learn a method from a senior or teacher by a specific procedure. The more you use a method, the more likely you will be convinced of its effectiveness. One tends to think that this method is the only right way to proceed and regard using the method as an objective. But there is no universally correct procedure suiting all circumstances. As a result of this, many organizations tend to simply follow precedents and this invariably causes a disagreement around methodology.

Moreover, there is an enormous variety of methods in each field, so needless to say we cannot master all methods, but we can master the Principle of Method. If we apply methods according to this Principle, they can be used to greater effect.

We would say the origin of essential management science might be Peter F. Drucker, the father, and inventor of modern management. He is the only one who has left essential insights in many books and articles, unlike modern academic management science, which completely depending quantification using statistics.

Almost all social scientists behave regarding publishing many papers based on quantitative research method using statistics as a goal. However, all evidence depends on the past however our society is changing at all times. So, past evidence has such fundamental limitations in social science. Evidence would be useful to grasp an essential points of things but the evidence is a just tool to grasp essential points, not the ultimate goal of social science. It would be too obvious to say, but as we have pointed out, we often regard a method as an ultimate goal.

We never refer to academic papers in 50 years ago. However, only Peter F. Drucker’s truly authentic books including his universal essential insights are universal so it still rightly guide many managers around the world.

However, Drucker seems to be not received a reasonable reputation in modern management studies. His achievements not using statistics are often considered old-fashioned and not “scientific” in the academic management science field, but that is not true.

What Drucker stated went beyond too far ahead and there was no academic foundation at that time. So now the alternative paradigm differently from the modern management studies is formed. Structural constructivism, a universal academic meta-theory, allows Drucker’s management theory to be recreated as an academic framework Essential Management Science giving scientific methodology with verifiability and upgradability not sticking to qualification. Drucker’s Universal insights will remain useful and be upgraded after 100 years, 1000 years in EMS.

For these reasons, the Essential Management School is the only accredited by the Drucker Society of Japan. It is also the first school to be certified for future education by the Future Education Council.
