Dialogue, Debate, and Discussion

Today I was wondering about the difference between dialogue, debate, and discussion. I could think of the following points. I look forward to have getting inputs to make to sharper.

Dialogue	Debate	Discussion
It is a collaborative/cooperative exercise. In this case multiple sides work toward a shared understanding	Debate is competitive and/or oppositional exercise. Here multiple sides try to prove each other wrong.	Multiple sides try to work towards achieving a common goal. However, each party holds on to a point of view and rather than trying to prove the other party wrong, the intention is to talk about issues less passionately.
In dialogue, one listens to understand, to make meaning, and to find common ground	In debate, one listens to find flaws, to spot differences, and to counter argue	Here both types of action can take place.
Dialogue enlarges and possibly changes a participant's point of view	Debate defends assumptions as truth;	Parties tend to search more about each others point and have higher regard than debate for another persons point of view
Dialogue creates an open-mined attitude. An openness to being wrong and an openness to change	Debate creates a close-minded attitude. A determination to be right.	Discussion often tends to lead toward one "right" answer
One submits the best thinking expecting that other person's reflections will help improve it rather than threaten it	One submits the best thinking and defends it against challenges to prove that it is right	It is a mix of both debate and dialogue actions.
Dialogue calls for temporarily suspending of one's beliefs	Debate calls for investing wholeheartedly in one's beliefs	It is a mix of both debate and dialogue actions.
One searches for strengths in all positions	One searches for weaknesses in the other positions	It is a mix of both debate and dialogue actions.
Dialogue respects all the other participants and seeks not to alienate or offend	Debate rebuts contrary positions and may try to demean other participants	One respects other participants. However, if something goes wrong, elements of debate are explicit.
Assumption: many people have pieces of answers and that cooperation can lead to a greater understanding	Assumption: a single right answer that somebody already has	No prior commitment on one single right answer. One tries to arrive at some set of solutions
Dialogue remains open-ended	Debate demands a conclusion	It can be either way
Dialogue is mutual inquiry, collective knowledge	Debate is individual opinions/ individual knowledge	Discussion is also individual opinions/individual knowledge
Practices a product	Produce products	Produce products
Dialogue is divergent	Debate is convergent	Can be either way, however normally convergent
