&gt;&gt; The time between picking the next most valuable feature and putting it in front of paying customers, is the one loop that needs to be optimised.<p>Well said, BUT how to determine that next most valuable feature? I worked on a product once that required quiet involved sales engineering support, feedback from the sales engineers doing POC on customer sites was, to me, the most valuable feedback of all. But for other low touch or consumer targeted products, I&#x27;m baffled how to do this.
