If you are a management professional, then you probably already know who Peter Drucker is. If you aren’t, you might be wondering, “what is Peter Drucker best known for?”

Well, Peter Drucker was one of the first people to believe that management had a distinct philosophy with a unique function and that managers themselves had a specific responsibility. He wrote many books on the subject and his work is used in management theory today.

Drucker was born in Austria and lived in Germany following WWI. Next, he lived in London, married, and moved to The United States. He became a naturalized citizen in 1943 and taught business at university level.

In 1971, he developed the first executive MBA program. It is no wonder people often called him “the father of management thinking.”

What did you learn from these Peter Drucker quotes?

Peter Drucker is near to my heart, as I hold a Master of Science in Management and Leadership. One of my biggest pet peeves in today’s business world is that people who have no business managing anyone are put in these roles as a reward for seniority or doing their job well.

Then the organization leaves them there to figure out how to lead people. Most do not receive the training and knowledge they need to be successful or help their subordinates become successful. It essentially sets everyone up for failure. 

If companies would invest more in teaching their leaders how to be leaders, they would see much better results. As Peter Drucker mentioned, corporations have to pay attention. Sadly, they are often focused on the wrong things and miss the bigger picture that the role of management has on their organization.
