It&#x27;s amazingly difficult to find the right metric when you are still at the MVP level.<p>However, once the system has proven itself, it&#x27;s only a matter of optimization.<p>I think it&#x27;s one (amongst many) reason why so many startups fail at the MVP stage. Looking for metrics at that stage is just speculation; optimizing for them is a complete waste of time. The focus of the MVP is to build a proven system without getting lost (minimal waste of time&#x2F;effort&#x2F;resources).
