The document describes 9 different leadership behaviors that can occur in groups: initiator, interpreter, analyzer, harmonizer, encourager, blocker, domineering, clown, and assertive. The initiator gets the group started, the interpreter clarifies ideas, the analyzer critically analyzes ideas, and the harmonizer reduces tensions. The encourager encourages acceptance of ideas, while the blocker opposes ideas and the domineering try to manipulate the group. The clown jokes around but may not add productivity, and the assertive keeps the group on task and time.
