Management

The reaction set in almost at once, and it came, fittingly, from another attempt at measurement. Between 1924 and roughly 1932, researchers ran experiments at Western Electric's Hawthorne plant outside Chicago, trying to find the lighting level and rest schedule that would squeeze out the most productivity. The results refused to cooperate. Output rose when they brightened the lights and rose again when they dimmed them. The variable that seemed to matter was not the physical conditions at all but the fact that the workers knew they were being watched and felt, for once, that someone cared what they thought.

Elton Mayo, a Harvard researcher associated with interpreting the findings, drew a conclusion that unsettled the Taylorist picture. Workers were not isolated units responding to incentives and instructions; they were social creatures embedded in groups, motivated by belonging, recognition and the informal norms of their peers. A team could quietly agree to hold output down no matter what the pay scheme promised. Morale was not a soft extra. It was a lever, possibly the main one.

By mid-century the manager was no longer a curiosity but a profession with credentials, and the person who gave that profession its confidence was Peter Drucker. An Austrian-born writer who had watched General Motors from the inside during the war, Drucker published The Practice of Management in 1954 and more or less invented management as a subject you could think about whole. His claim was expansive: management was the defining organ of modern society, the thing that made large-scale cooperation possible, as important to the corporation as government was to the state.

Drucker shifted the frame away from both the stopwatch and the psychology experiment. The manager's real task, he argued, was to decide what the business was for — to set objectives, allocate resources, and judge results against goals rather than against motion studies. His idea of management by objectives handed workers a target and trusted them to find the route, which quietly folded the human-relations insight into a workable method. Ask what the enterprise is trying to achieve, then organize everything backward from the answer.

Step back from the parade of gurus and a stranger pattern shows itself. Management does not behave like a field converging on truth. It behaves like a field where several convincing answers coexist permanently because the underlying question has never been settled. And the question is deceptively simple: what, exactly, is a company? Depending on how you answer, a completely different school of management becomes obviously correct.

Say a company is a machine for converting inputs into outputs, and Taylor's descendants are right: measure everything, optimize the process, chase efficiency. Say instead it is a community of people whose cooperation cannot be commanded, and the human-relations tradition wins: culture, trust and motivation are the real work. Say it is a bundle of contracts among self-interested parties, and you get the economists' view that dominated the 1980s — align incentives, watch for people gaming the system, tie pay to shareholder value. Each account is internally coherent. Each generates sensible advice. None can absorb the others.

Taylor stood before Congress in 1912 convinced he had found the one best way, and he had opened something far larger and far less tidy than he intended. A little over a hundred years later, the manager he helped invent is everywhere — in every company chart, every corner office, every business school lecture — and yet the discipline built around the role still cannot agree on its own foundations. The stopwatch gave way to the morale survey, which gave way to objectives, incentives, quality, agility, each certain it had finally cracked the code.
