Adding people feels like a shortcut to speed, but it creates a hidden coordination tax that eats productivity. Each new hire introduces additional hand‑offs, more meetings, and a larger decision‑making surface where information must travel farther. The cost grows faster than the marginal contribution of the extra headcount because existing members spend a growing share of their time keeping the expanded network aligned rather than delivering value.

In 2014 Zappos announced its shift to holacracy, exploding the number of role‑circles from a few dozen to several hundred within a year. The experiment produced a flood of cross‑circle syncs, and employee surveys showed a sharp rise in perceived “process overload” while net promoter scores slid. The organization eventually reverted to a more traditional hierarchy, shedding dozens of circles and reclaiming the bandwidth that had been lost in coordination.

The lesson is not that teams should stay tiny, but that scaling headcount without redesigning information pathways creates a “coordination drag” that throttles output.
