10-Foot, 3-Second Rule

Last updated by Jeff Hajek on May 31, 2023

The “10-Foot, 3-Second” rule is a rule of thumb regarding visual controls. From 10 feet away, you should be able to assess the status of an operation within 3 seconds.

This does not mean that a novice needs to be able to do it, but someone who is familiar with the visual controls should be able to interpret the situation quickly and in passing. That means that visuals need to be big, and they need to be followed. The process must be clear, and standard work-in-process must not be violated.
