That is - I've been on lots of low functioning teams riven with conflict. Prima donna developers who publicly call managers/teammates stupid in meetings. Managers giving negative feedback in public instead of in private. Stubborn veteran team members telling newer team members to get a new job if they don't like how things are done.
One pattern I've seen in lower functioning teams with lots of conflict is some members being very well spoken, typically more classically trained like a philosophy background, probably a past debate club type kid. "Strong opinions, loosely held" type behavior where bad ideas were passionately argued by the more eloquent & aggressive team member until everyone else was exhausted and just let it run.
The kind of guys that would steamroll the rest of the team as a bunch of idiots for not agreeing with him, but flip to a charismatic "ah good point" when incontrovertible proof of their idea not being correct was presented. The problem is you can't provide incontrovertible proof in real time in most cases, and lots of managers confuse their passion/certitude for correctness.
So high functioning teams can have heated arguments & difficult people, but heated arguments do not in themselves lead to high functioning teams.
