Query: The PRACTICE, not THEORY, of Managment

Peter Drucker wrote this book at the height of the mis-application of statistics and "science" in areas such as management and economics. Drucker, who had the benefit of experience, saw the flaws decades before the rest of us. I suspect that the reason Drucker was so ahead of his time is that he was able to tap the experience of the great industrialists who probably were unwilling to share the trade secrets of their management knowledge with the general public. It wasn't until the 1980s when the masses began to learn these things.The book is a classic and is just as valid today as it was in the mid 20th century (why wouldn't it be?).Drucker explains within the book the reason for the word "practice" rather than "theory" of managment.
