Without vision, people will define their own vision and the loudest voice will prevail.
Without strategy, people will do what they're most passionate about whether or not it helps the organization fulfill its mission.
Without clear communications, people will assume for themselves what's most important.
Without encouragement, people will gravitate to the first person who gives them attention when they need it.
Without leadership, people will follow the leader they choose or assume they're the leader.
When there's a void, it always gets filled.
