"Where the line is more blurred is around interface and/or interaction design. Some development teams have interface designers as part of the team. Some companies organize with interface design as a “shared service” within the company. Either approach can be the “right one” – it depends on too many details to make a sweeping generalization. When the designers are members of the development team, the solution (from a product management perspective) is the same – the “team” is responsible for all design. When the designers are not part of the development team, the developers have to consume two sets of guidance – “solve this problem” from product management, and “the solution needs to look like / act like this” from the designers."

"The prerequisites for ownership are said to be egalitarian, but in practice they’re not. The seeds of ownership require opportunity and circumstance, but maintaining ownership requires something else entirely. And the nature of business ownership makes owners a self-selected group. The most successful business owners are those who know how to inspire fanatical contribution to “the dinner party” while maintaining a stingy budget. Not everyone is cut out for that."
