Collaboration / Committees

Normally the latter is confused with the former.

Collaboration to me is getting everyone involved and working together, having ownership and input into a solution. This requires a commitment from the client to give their time, and from the agency to listen to the client without thinking they know-it-all.

Committees are ways of making sure that everyone can feel like they've had a say into a project but don't have to put much effort or thought into it. Generally involves far more people than necessary being in a room, all desperately trying to think of something to say that will show they're useful, knowing they don't have to worry about the consequences.
I've been there. Both running the meeting, and as the worrier.

My recent projects have (fortunately) been much more towards collaboration than committee.
