Envisage you are part of a team when there are conflicting opinions about a deal. What would you do?

Personally i would form two teams who agree and who do not agree 

The teams who give more logical and practical reasons, would be the ones whose opinions would actually be considered.

Simultaneously the team who disagree should also have trust in the final decision.

Team orientation with expected goals from the task and discussion on possable challanges with remidies to get the team closer and work togather for sucessful outcomes

For these cases there are a few things you could do in order to bring the parties involved into an agreement:

1.- Listen carefully and actively so you can stay engaged with the speakers to summarize conversations, this way you can ensure effective information exchange.

2.- Manage the expectations keeping in mind that negotiating allways reduces conflicts among the parties

3.- Enhance the skills of all team members so you can motivate people providing encouragement or reassurance

4.- Negotiating to achieve mutually acceptable agreements between parties and reduce approval or decision delays 

5.- Finally monitoring and measuring the effectivness of the agreement to prevent disruptive impacts
