In principle, members of high-functioning groups are focused on the success of the group as a whole rather than on who should get credit or blame within the group. Harry Truman said, "It is amazing what you can do if you do not care who gets the credit." Similarly, groups get more done when unconcerned with assigning blame.
Rather than spend energy accounting for past individual credit or blame, it is better to invest lessons from the past into future good group decisions. When I believe in my group I know that, over the long run, what is good for the group will be good for me - probably better for me than I could ever have achieved on my own.
Practical Tip: Give your ideas and efforts to the group without conditions, without lingering ownership. Welcome contributions from others without jealousy, without resentment. Show public appreciation for others in your group. Own your share of things gone wrong and credit the group for things gone right.
A mark of a high-functioning team is that each member wants to make other members look good.
