Experimentation is crucial for checking if our ideas hold water, especially because it lets us test assumptions in real-world situations. It's like a hands-on test to see if what we assume actually works. By doing organized tests, collecting proof, and adjusting our ideas based on real outcomes, we make sure they're solid and can stand up to the real world. Additionally, experimentation allows us to quickly discard ideas that don't have evidence supporting them, helping us focus on the ones that show promise and increasing the efficiency of our innovation process.
