Leadership consultant Kevin Eikenberry on not making zero conflict a goal:

Put people together doing most anything for most any length of time and conflict will occur. Put people together and ask them what the challenges are at work, and conflict will always come up. People have experience and an opinion about conflict, and they don’t talk about positively. We face conflict and generally think if we could rid ourselves of it, we would be better off. Yet, we must be careful about what we ask for, because zero-conflict shouldn’t be the goal.
