Transparency and keeping everyone informed, as alluded to by Sir Humphrey, is important. I am not sure if this is exactly on topic but my experience is that a lot of disputes stem from the two differences between two types of owners.
Group 1: Most owners serve on committees on a voluntary non paid basis. Sure you get the odd control freak who serves out of self importance but most take on a job no one else will do.
Group 2: Most owners are pretty reasonable and co-operative but some won’t do a thing whether that be serve on a committee or the occasional task.
Often Group 1 can come to feel that as they do all the work it is their right to make sure things are done as they believe they should be done. Sometimes this view extends to Group 1 advantaging themselves. This angers Group 2.
Often Group 2 members won’t do a thing until it is something affecting them and then they want it done immediately and jump up and down about it. I have seen cases where such owners have demanded repairs affecting their unit but won’t do anything to facilitate them being done as that is “the committee’s job” This angers Group 1.
Anger ends up in name calling and each group attempting to embarrass the other!
