Druker coined the term "Knowledge Worker", and his series of lectures on knowledge is extremely relevant especially to Singapore. We have no natural resources to export, we have little low end manufacturing in Singapore, so all that we are left with is the so called knowledge-based economy. Play around on this animation and you'll see the value and productivity of different industry in Singapore.
But what is knowledge? Druker first talked about information. He said that we are in an age (1986) of people drowning in data, not information. And we will have to learn that more is less, and that data is not information. And information is something that has to be selected. "Information is something that is pertinent to the task that can be converted into knowledge. And knowledge is information in action. One has to learn this."
With this growth in information, we will have many fewer layers of management and many more specialist. He drew on the analogy of a large symphony orchestra, where the triangle player has no ambition to become a bassoonist, and none to become first violin. And looking at university size, he lamented that with the growth in student population, sooner or later there'll be need for more vice president than student. It will be interesting to review the staff to faculty to student ratio in Singapore over the last 20 years.
Drucker drew on all branches of learning that he could. He said, "Every three or four years I pick a new subject. It may be Japanese art; it may be economics. Three years of study are by no means enough to master a subject but they are enough to understand it. SO for more than 60 years I have kept studying one subject at a time. That not only has given me a substantial fund of knowledge. It has also forced me to be open to new disciplines and new approaches and new methods--for every one of the subjects I have studied makes different assumptions and employs a different methodology."
His ability to bring knowledge and wisdom down from academic stratosphere into the nuts and bolts of what should be done is astonishing. He probably lived his life to the Confucius words: 博学之,审问之,慎思之,明辨之,笃行之。
