The KISS principle (acronym for "Keep It Simple, Stupid") states that design simplicity should be a key goal and unnecessary complexity avoided. It serves as a useful principle in a wide array of disciplines, such as software development, animation, engineering, and strategic planning. Common variants of the acronym include: "Keep It Sweet & Simple", and "Keep It Short & Simple". The form "Keep It Simple, Silly" is sometimes used in situations (for example, explaining the phrase to children) where "stupid" may be perceived as being too harsh.

Complexity should be avoided—simplicity is a goal in itself. Extra features are not needed; an approach that seems "too easy to be true" is in fact the best way. A very straightforward approach may seem less glamorous and less dramatic, but the trivial approach should indeed be taken. Surprisingly, the very obvious approach is often the best.

The principle is somewhat similar to Occam\'s razor, and Albert Einstein\'s maxim that "everything should be made as simple as possible, but no simpler."Hoch, Stephen (2004). Wharton on Making Decisions. New York: Wiley, 137. ISBN 0471689386. , or Antoine de Saint Exupéry\'s "It seems that perfection is reached not when there is nothing left to add, but when there is nothing left to take away".

Rube Goldberg machines illustrate the sorts of problems that may arise with "non-KISS," overly-complex solutions.

Instruction creep and function creep are an example of failure to follow the KISS principle in software development.

In film animation

Master animator Richard Williams explains the KISS Principle in his book The Animator\'s Survival Kit and Disney\'s Nine Old Men write about it in their "Disney Animation: The Illusion of Life" book which is considered "the animation bible" by CG, traditional, and stop motion animators. Inexperienced animators may "overanimate," or make their character move too much and do too much, such as carrying every accent over into body language, facial expression, and lipsync. Williams urges animators to "KISS."
