Demonstrates reliability
You can count on a reliable team member who gets work done and does his fair share to work hard and meet commitments. He or she follows through on assignments. Consistency is key. You can count on him or her to deliver good performance all the time, not just some of the time.

Communicates constructively
Teams need people who speak up and express their thoughts and ideas clearly, directly, honestly, and with respect for others and for the work of the team. That's what it means to communicate constructively. Such a team member does not shy away from making a point but makes it in the best way possible — in a positive, confident, and respectful manner.

Listens actively
Good listeners are essential for teams to function effectively. Teams need team players who can absorb, understand, and consider ideas and points of view from other people without debating and arguing every point. Such a team member also can receive criticism without reacting defensively. Most important, for effective communication and problem solving, team members need the discipline to listen first and speak second so that meaningful dialogue results.

Functions as an active participant
Good team players are active participants. They come prepared for team meetings and listen and speak up in discussions. They're fully engaged in the work of the team and do not sit passively on the sidelines. Team members who function as active participants take the initiative to help make things happen, and they volunteer for assignments. Their whole approach is can-do: "What contribution can I make to help the team achieve success?"

Shares openly and willingly
Good team players share. They're willing to share information, knowledge, and experience. They take the initiative to keep other team members informed. Much of the communication within teams takes place informally. Beyond discussion at organized meetings, team members need to feel comfortable talking with one another and passing along important news and information day-to-day. Good team players are active in this informal sharing. They keep other team members in the loop with information and expertise that helps get the job done and prevents surprises.
