Blaine Collins quote the 5 "C"s of good teamwork from Akhil Shahani as:

• Clear expectations: Each team member knows their role and expected contribution.
• Channels of communication: Team members share openly with one another and the team fosters communication within the organization.
• Conflict resolution: Team members work to resolve differences directly, with mutual respect.
• Consequences: Team members are responsible for, and accountable to, one another.
• Celebrating achievements: Team members jointly share in the team’s success.

and then adds 3 more of his own:

• Coaching: Team members share insights and knowledge with one another to boost individual development.
• Collaboration: Team members build on the efforts of one another to achieve objectives that would be unattainable alone.
• Community: Team members develop bonds that lead to supporting each other both professionally and personally.

As I look through them I find myself agreeing wholeheartedly.  But then, of course, I look at my performance of these "C"s in the teams I lead and know I should be doing better!

So right now I resolve to work on the 2 "C"s that I feel I do worst at...  Clear expectations and Celebrating achievements.
