Why would I want silly games in my business? Won’t that just give people another reason to goof off at work? Gamification isn’t about making games, it is about applying to processes and communication the same type of techniques that keep people interested and engaged in playing games.
Wikipedia has a great definition, an excerpt below:
Before you go and jump in the pool and enlist someone to gamify all your processes, understand that in order for it to work and provide tangible benefits to the organization, the psychological and emotional rewards offered need to be in alignment with what you are trying to accomplish. Additionally the behaviors that are being rewarded need to be carefully evaluated to prevent the inadvertent reward of undesired alternate behaviors, such as “gaming” the system or introducing a type of peer competition that can be damaging for morale.
