I work in advertising and this is the analogy I use when preparing a client for a creative project- that you have to decide whose vision you’re creating (typically businesses have many stakeholders in creative decisions). Every person will have a different vision of the outcome despite the same inputs and parameters. So similar to a movie- only the director will think “this is exactly what I envisioned”, everyone else will find that elements are “off” from what they imagined. But it’s impossible to realize everyone’s vision - whether you’re making a movie or any creative project.
