Before launching a business intelligence project, a communications analysis and plan is a must. For a small project, this is probably done mentally-who needs to know I am doing this? Who might put in duplicate effort if they don't know I am working on it? But for a larger project, a written communications plan will direct your communications efforts and keep you on track. You need to think about who needs to be informed of your project and its progress, how will they be informed, how often. What do they care about? What do they need to know? And how will you tell them?
