Depends on the style of the company. Different companies would say different things about this. Apple: "Bad advice. Let a "Jon Ive" type design-lead think through the product and detail every page of it. Don't let engineers run product. Give them the ability to give feedback on product, but give the ultimate authority to somebody who understands human emotion, art, UX, etc" Google pre-Page: "Good advice. Engineers should control product. They are smarter than everybody else, and therefore will make the best software." The reality of these company's positions is more nuanced than this, but these caricatures have their place in helping to understand how they think.
