I think "design by committee" is a better target for criticism than collaboration in general.

If you get a bunch of people in a room and ask them for a design, one person is going to write the design while everyone else gets in the way. That's simply the nature of groups. The one person who writes it isn't even necessarily the best designer—they're just the one most willing to grab the whiteboard marker.

Conversely, if you ask one person to produce a preliminary design, they can leave, gather requirements, do research, produce a plan, and then convene everyone in a room to review it. Now all the abstract hypotheticals have been put to bed, the nebulous directionlessness has been replaced with a proposal, and the group can actually provide useful feedback and have a discussion that will inform the next draft of the design. And once the design is finished, everyone can easily work together to implement it as written. Collaboration is great, after someone has proposed a design.

That's part of what I like about the idea of Amazon's "culture of writing," though I've never worked in an environment like that in practice. Every idea needs to be preprocessed into an actionable memo before anyone tries to have a meeting about it.
