I agree with soror BlueReign. Embarrassment can cure alot! But at the same time, if you can help it, you dont even want the embarrasment. That could damage the credibility of your org on campus (or wherever).
Maybe an E-Board change is needed. Make it clear to executive officers that if they dont get their committees together, that they'll be relieved of their duties. Someone has to step up to the plate! Im sure an eager committee member would be more than willing to get that position. (New Blood is sometimes--but not all the time-- the best blood!) If the problem is EVERYONE's fault, then u just have to make it clear to them that the reputation and existence of yall org is in danger. They don't want to be remembered as the group that brought about the end of the org. (and its funny how FAST I've seen some groups fall apart.)
Ultimately, if they want it bad enough, that'll put a battery in thier back.
Good Luck
