Communication starts the process of building a connected team. To connect with someone, you must communicate with them. Relationships are the foundation upon which great teams are built, and communication serves as the initial foundation in building a great relationship. Communication builds trust. Trust generates commitment. Commitment fosters teamwork, and teamwork delivers results. Without great communication, you don't have the connection and trust to build a strong relationship. And without strong relationships, you can't have a strong team.
