That's how some steps of the science work, specifically the empirical studies. Empirical validation, falsifiability, and repeatability is all in that ball-park. But it's a part of the process and not all of it.

If that's the only thing you want to consider, sure. As a layman it's probably a good principle, and more so in engineering. But you'll have to shave off some significant works of science from history if you do that.
