This document discusses lessons learned about effectively applying gamification in the enterprise. It notes that work already involves many elements of games that are often poorly designed and can have unintended consequences. Successful gamification requires carefully designing around intrinsic motivations like meaning, autonomy, and mastery. It also requires getting experienced game designers involved and iterating slowly to amplify positive existing behaviors while minimizing negatives. Simplicity is important to avoid unintended issues from game elements in a work social context.
