Businesses that do not develop specific business plans have a greater chance of failure than firms that do. Go outside and ask a few people what the corporate vision and mission are. You'll be horrified. You'll want to kick the communications management where it hurts. I have conducted a lot of planning sessions with and for a variety of organisations, and everybody likes visions, missions, goals, objectives and strategies.
Participants readily contribute to the brainstorming.
Plans without strictly implemented and monitored actions are a waste of time.
