Many of my clients are now in “big data” and need to explain why what they do is so clever.

One approach to do this is the mathematical research paper approach: describe the algorithms and point out on what data sets they work.

A much better one is the take one practical case example throughout your entire presentation. Show how you searched millions of health records, cross matched them with facebook location data down to the square kilometer, overlayed that with climate data for the past 300 years and came to this very targeted, very unexpected insight that you would never have found out using a Google search, buying a research report, or other 2 common search methods.

The scientist will like approach number one: no ambiguity and a perfect explanation. The rest of us will prefer option two.
