Peter Drucker told companies to ask what business they were in.
The practice of corporations articulating a formal purpose traces to the management philosophy of Peter Drucker. In his 1973 book Management: Tasks, Responsibilities, Practices, Drucker argued that the first responsibility of top management was to ask the question "What is our business?"1 The question, he wrote, was almost always difficult and could only be answered by looking at the business from the outside, from the perspective of the customer.
Drucker had been developing this idea since the 1950s. His 1954 book The Practice of Management introduced the concept of management by objectives, which required organizations to define their purpose before they could measure progress toward it.2
By the 1980s, the mission statement had become a standard corporate artifact. Consultants encouraged companies to display their mission in lobbies, annual reports, and employee handbooks. Strategic planning frameworks of the era, including those popularized by the Harvard Business School, formalized the mission statement as the first step in any business strategy.3
Academic research followed. A 1987 study by Fred David in the Academy of Management Executive analyzed mission statements across industries and found that most included references to customers, products, markets, technology, and self-concept.4
The proliferation created a genre with predictable patterns. Critics noted that many mission statements were interchangeable, filled with words like excellence, integrity, and innovation that conveyed aspiration without specificity. A 2014 analysis in the Journal of Business Ethics found that more than eighty percent of Fortune 500 companies had published mission statements, though the relationship between stated missions and actual corporate behavior varied widely.5
The word mission itself comes from the Latin mittere, meaning to send, a term originally associated with religious orders dispatched to spread faith. Corporate mission statements borrowed the vocabulary of calling and purpose from religious and military traditions and applied it to organizations whose primary obligation was to shareholders.6
