The term was used by the Internet Engineering Task Force (IETF) in describing its procedures for working groups (WGs).
(However, "dominance" is not to be determined on the basis of volume or persistence, but rather a more general sense of agreement).
It is up to the Chair to determine if rough consensus has been reached (IETF Working Group Guidelines and Procedures).The phrase is often extended into the saying "rough consensus and running code",[2] to make it clear that the IETF is interested in practical, working systems that can be quickly implemented.
There is some debate as to whether running code leads to rough consensus or vice versa.
The IETF published a subsequent document pointing out that supporting percentage is less important for determining "rough consensus" than ensuring opposing views are addressed.
