CORE DEFINITION

When a system becomes so complex that only a few experts can understand or maintain it, its development speed inevitably drops sharply or even stalls. Complexity itself becomes the brake on growth.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Simplify instructions. When project progress inexplicably slows down, don't just add people. Check if the system is too complex (documentation too long, code too messy, processes too cumbersome). Subtraction (simplification) is the only accelerator.

anchor

Anchor fast decisions

The marginal increase in system complexity brings a superlinear rise in maintenance costs. When a system becomes so complex that only a few experts can understand it, any change requires lengthy communication and high-risk argumentation, causing overall delivery speed to plummet—complexity itself becomes the brake. The mechanism lies in the cognitive load ceiling and coordination costs growing exponentially with coupling.
