Strategy consultants or IT architects love the diagram-that-brings-it-all-together. Customer needs, key capabilities, competitive differentiations, routes to market, all glued together in harmony to describe that perfect concept. It makes perfect sense to you.
The problem: it is too much to digest for the person who sees the diagram for the first time.
One better approach is to start with stories for the individual bits of the concept, and only in the end stitch everything together. If you feel it hard to part with that diagram early in the presentation, you can put it up and jokingly brush it aside/apologise and say you are taking it a bit slower. After you have explained a component of the diagram you can slowly build the picture up step-by-step.
