What term is defined as the process of introducing something that is new?

The term that is defined as the process of introducing something that is new is "innovation." Innovation involves taking existing ideas, technologies, or methods and improving upon them, or creating entirely new approaches to problems or needs. It signifies not just the idea of being new but also the application of these ideas in a way that adds value or solves a problem.

While "invention" might relate closely to the creation of something entirely original, innovation emphasizes the practical application of new concepts to enhance or transform a particular field or industry. "Revolution" generally refers to a significant and rapid change that often has a far-reaching impact, but it doesn't specifically denote the introduction of something new in a systematic or practical manner. "Creation" can be broader and includes bringing something into existence but may not always carry the connotation of improvement or application that innovation does.
