We presented this deck at the ESOMAR Congress 2011 conference in Amsterdam where it was nominated for "Best Methodological Paper".
The meat of this deck is a collection of case studies showing the efficacy of gamification in various BUSINESS contexts. It took us ages to contact and collate these various examples, so hopefully having them all in one place will save you time.
A big thank you very much to the various folks who helped us put this piece of research together!
If you have any questions, comments, requests, or are interested in the original paper that this deck is based on, please feel free to drop us a line :)
