The word "implemented" refers to the process of putting into action a plan, idea, policy, or system. It means to execute or carry out something that has been decided upon. For example, when a school decides to introduce a new teaching method, they would implement that method in their classrooms.
The word "implemented" comes from the Latin word "implementum," which means "a filling up" or "that which fulfills." The root "implere" means "to fill." The term evolved through Old French before entering Middle English in the sense of making something happen or fulfill a plan.
