Etymology

Origin of implementation

implement + -ation

Explanation

Implementation refers to the carrying out a plan, like your school's implementation of the new dress code that will start in August — for now, you can keep wearing your jeans. Implementation is the noun form of the verb implement, or "to carry out or accomplish," and you’ll often see it used in reference to a government plan or act. Use this word to describe the process of turning formal plans — often very detailed conceptual plans that will affect many — into reality. For example, the implementation of new parking fees means everyone has to put more money in the parking meters.
