Specifically in my group, what I would tell them all the time is, we need to do three things consistently, and repeatedly:
We need to measure things, we need to test hypotheses, and we need to try all kinds of random things — especially the things that may sound silly, or wrong, or stupid.
And the reason is because it allows you to take the ego out of running a company. Ego and arrogance are poisonous in building successful organizations. And so these three things, in my opinion, do more to create a culture of transparency and openness, where you can stumble into, and hopefully find, product leverage in a B2C company.
