Teammates do not always see eye to eye. Teams that agree all the time either have a diversity problem or a lying problem. Teams that are made of secure and mature adults can disagree and move forward. Insecurity and immaturity can limit a team when disagreements threaten the necessary unity. People disagree and great teams understand this. The team dynamic is dysfunctional when a teammate is seen as a threat to unity simply because they disagree. Agreement is not necessary for unity, but healthy debate is.
