When people do not share a common language, it can lead to confusing, even hilarious results. Consider the classic Abbott and Costello skit “Who’s On First,” where both comedians are saying the same words but meaning completely different things. While this conundrum makes for great comedy, it can cause real problems in our organizations. And lack of a common language doesn’t just manifest in people assigning different meaning to the same word; it can also result in people using vastly different terms to describe the same thing. This can cause frustration, misunderstanding, and decreased efficiency as people decipher each other’s language.
