Do product managers need to have more power inside Google?

No, I don't think so. We bring together a team of people who are really passionate about [a] subject. I think it's interesting: We still don't do very high-definition product specs. If you write a 70-page document that says this is the product you're supposed to build, you actually push the creativity out with process. The engineer who says, you know what, there's a feature here that you forgot that I would really like to add. You don't want to push that creativity out of the product. The consensus-driven approach where the team works together to build a vision around what they're building and still leaves enough room for each member of the team to participate creatively, is really inspiring and yields us some of the best outcomes we've had.

I wonder if 7 years later that is still true?
