Five dysfunctions of teams

Anglican Cell Church site has a useful pointer to a management book with a useful-seeming core content.

Each ‘dysfunction’ is caused by a failure to address the previous one.
They are
1. Lack of trust: We’re working together but I don’t share anything vulnerable of myself in the process.
2. Lack of conflict: We don’t genuinely say what we think as issues are discussed, feeling free to disagree vigorously.
3. Lack of ownership: Because I didn’t express my reservations, I don’t fully buy into the process and decisions.
4. Lack of accountability: We don’t hold one another accountable to follow through on the things we are each responsible for.
5. Lack of commitment to team results: To use a football analogy (painfully current!) a player finishes a match elated that he scored a hat-trick even though his team lots 4-3.

In my experience these seem right and it's good to have a one-stop place to see them laid out. I'll have to think further to see whether I think there are more things I'd want to add or whether there is a greater synthesis of these reasons.
