I've found consensus decision making to be frustrating in the environments I've encountered it.

A lot of flip flopping and lack of follow through.

Who made that decision? We did. Can we give up on that and try something else? Of course.

I kinda like to have at least a shepherd for the day to day decisions, if not a commander.

In practice in my current environment it's been the occasional PM that takes some ownership that fills that role, but in many groups I see the floundering without leadership.

Internally I think they think they're making progress because everyone on the team is always happy with their decisions, I may just be the old curmudgeon that's frustrated with what I see as wasted effort.
