Zappos, the online clothing retailer and Amazon subsidiary, has spent the past year and a half conducting a peculiar experiment. It’s called holacracy, and it’s the somewhat radical notion that the employees of some companies—like Zappos—would function better without managers in the mix. At Zappos, the project began in late 2013, when chief executive Tony Hsieh announced that the company would eliminate all titles and managers and transition to a holacratic structure.
