Some employees play mobile games on their smartphones at work--maybe even the person reading this will admit to doing it. That helps explain why the concept of "gamification"--where game-like elements are introduced to what are traditionally non-gaming activities--has become such a popular strategy in companies. A few years ago, research firm Gartner even predicted that by this year, 50 percent of organizations will use gamification to manage some of the most innovative things they do. As mobile game developers struggle to make enough money to have a sustainable business, experts say gamification may become one way they can develop a lucrative sideline rather than work on more traditional enterprise apps. Some are already specializing in this area, though it may mean learning some new skills and getting a handle on a very different breed of customer.
