We are trying an experiment with the a new product my company is launching.<p>We started out by writing down all of our assumptions, of which there are many. I&#x27;m not sure you can ever build any product or service without them, no can you successfully &quot;validate&quot; all of them (people&#x27;s actions don&#x27;t always line up with their words).<p>It&#x27;s actually really refreshing to be able to look and see, &quot;OK, there&#x27;s all of the stuff that we don&#x27;t really know, and our job is to invalidate any lore in there as quickly as possible.&quot;
