effective communication

Explanation:

One important characteristic that would help build such a relationship is effective communication. You are working with other individuals on a daily basis and are all contributing towards a bigger goal. Therefore, communication is key in order to know what can work and what can't. Communication also allows everyone to voice their ideas, thoughts, feelings, etc. and allow others to listen and understand so that they can adapt to what would be best in that scenario. This leads to respect, which leads to better and more positive professional relationships.
