Play has long infused the language of business: we talk of players, moves, end games, play books and so on. And now we hear often about the “gamification” of work—using elements of competition, feedback and point scoring to better engage employees and even track performance. Even so, actual games are still taboo in most organizations—the stereotype of the work-avoiding employee cracking new high scores in Minesweeper has given gaming a bad name. And the corporate executive playing games to improve his or her strategy-making skills is still rare. This is unfortunate. We think that games have an important place in cultivating good strategists, and that now more than ever games can give executives an edge over their competition.
