When I was a still a junior consultant at McKinsey, one of the senior partners on a team I was working on said that most consulting projects really generate only one truly original new idea/insight. The rest of the hard work is not really that original (1% inspiration, 99% perspiration as Thomas Edison put it)). Still, that one insight usually drives the entire recommendation.

At McKinsey, these truly new ideas were often the result of a novel way of combining facts/data sources for the first time and/or being able to quantify/compare things that nobody thought could be quantified.

Looking back at presentations and pitches I have worked on, the on truly new idea concept probably holds. Use it in your presentation design. Facts, and logic flows that everyone is already used to/knows are not interesting. It might be better to go quickly to that unexplored territory that you discovered.
