CORE DEFINITION

In multi-step biochemical reactions, the overall reaction rate is determined by the slowest step. No matter how fast other steps are, if the rate-limiting step is not accelerated, the total output will not change.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Precise force application. Similar to bottleneck theory, but applied in micro-processes. Identify the enzyme (key step) that determines the speed of your workflow, and optimize only that.

anchor

Anchor fast decisions

In the mechanism of a multi-step reaction, the slowest step (rate-limiting step) determines the overall reaction rate. The overall speed is constrained by the 'short board' step, not the average.
