2 PROJECT OVERLAYS SUPPORTING GRAPES STRATEGIC CHOICES

3 Answer the IAB question, How do all these projects fit into the big picture? Provide a template with which to organize our thinking and communication as we select and evaluate projects. Provide a document that can be passed on and used as a starting point for our Researchers, working with IAB members, to determine the projects we choose in the future. Provide an instrument for planning with the end point in mind.
