Refactoring is usually motivated by noticing a code smell. [2] For example, the method at hand may be very long, or it may be a near duplicate of another nearby method. Once recognized, such problems can be addressed by refactoring the source code, or transforming it into a new form that behaves the same as before but that no longer "smells".
Rule of three ("Three strikes and you refactor") is a code refactoring rule of thumb to decide when similar pieces of code should be refactored to avoid duplication. It states that two instances of similar code do not require refactoring, but when similar code is used three times, it should be extracted into a new procedure.
Structured analysis breaks down a software system from the system context level to system functions and data entities as described by Tom DeMarco. [1] Object-oriented decomposition breaks a large system down into progressively smaller classes or objects that are responsible for part of the problem domain.

Robert C. Martin calls a list of code smells a "value system" for software craftsmanship. [ 7 ] Contrary to these severe interpretations, Cunningham's original definition was that a smell is a suggestion that something may be wrong, not evidence that there is already a problem.

With the advent of C++11 the rule of three can be broadened to the rule of five (also known as "the rule of the big five" [5]) as C++11 implements move semantics, [6] allowing destination objects to grab (or steal) data from temporary objects. The following example also shows the new moving members: move constructor and move assignment operator.
