I would disagree with that. Much of creating art is a feedback loop. An artist rarely, if ever, has a fully formed picture in their mind of what a finished piece will look like, and it's even more rare that the final piece conforms to that image. In the process of creating, the artist takes in what is in progress and has to adjust accordingly. The final piece is influenced by the medium it's created in, the process of creating it, constraints both momentary and well-known, and the context of the time and whims of the artist.
