What is the KISS Principle?  

The KISS Principle, also known as Ockham’s Razor, is an acronym for a popular maxim, “Keep IT Simple and Stupid” or “Keep IT Simple and Straightforward”.

Restated, one should avoid complexity when undertaking any plan, design, or action, when possible. 

Ockham’s Razor is originally in Latin: “Numquam ponenda est pluritas sine necessitate”.

The translation of this principle of parsimony is: “Multiples should not be posited without necessity”.
