Gallup interviewed over a million workers and reduced the workplace to twelve questions.
In the 1990s, researchers at the Gallup Organization set out to identify which workplace conditions predicted performance. They interviewed more than one million employees across industries and countries, asking hundreds of questions about every measurable aspect of their working lives.1
From that data, Gallup distilled twelve items that showed the strongest statistical links to productivity, customer loyalty, retention, and profitability. The result, published in 1998, was the Q12.2
The questions do not ask about compensation or benefits. They ask whether an employee knows what is expected, whether someone at work seems to care about them as a person, and whether they have a best friend on the job.1 The "best friend" item was the most controversial. Gallup's research showed it was among the strongest predictors of team performance.
By the time the Q12 database exceeded five million responses, Gallup could benchmark organizations against 620,000 workgroups across sixteen industries and 137 countries.3
Gallup's 2024 State of the Global Workplace Report found that only twenty-three percent of employees worldwide qualified as engaged. Gallup estimated the global cost of disengagement at 8.8 trillion dollars in lost productivity, roughly nine percent of global GDP.4
The idea of surveying workers about their attitudes is older than Gallup's instrument. The Elton Mayo studies at Western Electric's Hawthorne plant in the late 1920s were among the first systematic attempts to measure how workers felt about their conditions. More than thirty-five million employees have now taken the Q12.
