Peter Drucker is considered the "Godfather of Management" for coining terms like "knowledge worker" and "management by objectives". His main belief was that people are an organization's most valuable asset and that there is no business without customers. He defined management as "the act of getting people together to accomplish desired goals" through planning, organizing, staffing, leading, controlling, and motivating. Successful organizations focus on customer satisfaction, loyalty, profitability, market share, and brand recognition.
