Not too long after color palette update, The election of three new board members to the client's organization (a non-profit, county-ish hospital)took a dire turn. The logo project, now well along its way to approval and implementation, got snagged on one member's demand that the board see two options and pick one. Well, this stage had been completed months ago and this turn of events would open the door to the living hell of multiple, unqualified opinions that would pass as genuine, working criticism.
Fortunately, the demand turned into a gripey email memo sent around to and reported by the local newspaper. I believe this has spent the board member's energy and he is moving on to other targets of his wrath. It only goes to show how one's best critical path to a design solution can instantly be derailed and tossed into committee hell. You can look all around this country and you'll be hard put to find a monument erected in the name of a committee.
One working alternative to the broad examinations of a group of individual's who's only common ground is that they were elected to a board is to require a contact/managing point person to handle the liaison between you and the board or committee. This will rarely be an optimal solution. Unless they have an amazing grip on the board, the point person will have to assemble, prioritize and relay the same information you are un-exposing yourself to. This, too, can lead to seemingly never ending revisions and frustration. But it sometimes, if the liaison is clever and resourceful, leads to a smoother, more intelligent process.
Try it, you have nothing to lose, and from my experience, about a one in three chance of it working.
