Murder board
（重定向自Murder boards）
A murder board, also known as a "scrub-down", is a committee of questioners set up to critically review a proposal and/or help someone prepare for a difficult oral examination.
The term originated in the U.S. military, specifically from the U.S. Pentagon but is also used in academic and government appointment contexts. NASA contends the murder board was created by Hans Mark, Director of Ames Research Center from 1969 to 1977.
