Individual responsibility can just become a blame culture. I remember sitting near a team that worked like this - meetings with everyone trying to prove that some screw-up was actually due to someone else.

In such scenarios nobody wants to stick their neck out at all, everyone hates everyone else.

At a higher level the usual problem is with incentives being different from one team to another. If you want something done you have to start with the incentives rather than expect people to work against them and there does have to be leadership to break deadlocks.

If ownership is clearly defined the person who screwed up should be clear.
