Over a period of time difference of opinion leads to debate following which mutual understanding might take place.
Somewhere down the line,
something might click,
then signs of mutual understanding will be there in offing.

Mutual understanding will bring the much needed change,
a change that's desired,
since it also fulfills the need of hour.

If mutual understanding takes place, then nothing like that since it moves in the direction of drawing a line of conclusion, which is the only reason because of which the debate commenced.
If mutual understanding is still a viable option,
yet far away,
then it’s time to keep negotiation apart and away from been a part of the debate.

Finally difference of opinion can lead to something positive and healthy, if the debate that is ensued following a difference of opinion is in the right direction,
in right spirit,
focus remaining on point of concern,
substance with regards to what’s going on in mind is not disturbed in anyway,
most importantly the debate is held on proper grounds.

Difference of opinion is also a sign for something constructive, if the mind is determined to make sure that the odds which are going to come along the way will not only be handled and tackled, but also taken out and taken away from the way of getting things done.

Finally it’s difference of opinion that makes team work interesting, if it is taken in the right spirit at the given moment in time.
