The document discusses the concept of "smoke tests" which are a way for companies to quickly test product ideas without needing developers by directly trying ideas on customers and measuring conversion. It provides an example of how one company tested the idea of an "Add to Box" feature by rapidly building and launching a simple prototype, which ended up significantly growing the company's profits and being a better approach than traditional lengthy development. The document advocates for this approach as a way to efficiently validate product backlog ideas and make better decisions.
