K.I.S.S. (Keep It Simple and Straightforward)

“KISS” (also called the “KISS principle” or “KISS system”) usually stands for “Keep It Simple, Stupid.” Like the harmless kiss, the KISS principle—used in the military, business and government—holds that the simple method is the most preferred. The Navy instituted a “Project KISS” in 1960.
 
The first “KISS” citation, however, appears in print in the Rocky Mount (NC) Sunday Telegram on May 4, 1958, and does not appear to be related to the military.
 
“Keep It Short and Simple” was printed in the Minneapolis (MN) Star in 1938 and The Wall Street Journal in 1948. “KISS Keep It Short and Simple” was printed in The Star-Phoenix (Saskatoon, Saskatchewan) on November 6, 1970.
 
“Keep It Simple Silly” was printed in the Alamogordo (NM) Daily News on September 19, 1971.
 
“Keep It Simple, Sweetie” was printed in the Sunday Post-Crescent (Appleton, WI) on November 4, 1973.
 
“Keep it Small and Simple” was printed in The Sunday Freeman (Kingston, NY) on May 23, 1976.
 
“Keep It Stupid, Simple” was printed in The Daily Oklahoman/Times (Oklahoma City, OK) on November 2, 1984.

Wikipedia: KISS principle
KISS, an acronym for “keep it simple, stupid” or “keep it stupid simple”, is a design principle noted by the U.S. Navy in 1960. The KISS principle states that most systems work best if they are kept simple rather than made complicated; therefore, simplicity should be a key goal in design, and unnecessary complexity should be avoided. The phrase has been associated with aircraft engineer Kelly Johnson. The term “KISS principle” was in popular use by 1970. Variations on the phrase include: “Keep it simple, silly”, “keep it short and simple”, “keep it simple and straightforward”, “keep it small and simple”, or “keep it stupid simple”.
   
Origin
The acronym was reportedly coined by Kelly Johnson, lead engineer at the Lockheed Skunk Works (creators of the Lockheed U-2 and SR-71 Blackbird spy planes, among many others).
 
While popular usage has transcribed it for decades as “Keep it simple, stupid”, Johnson transcribed it as “Keep it simple stupid” (no comma), and this reading is still used by many authors.
