When I wrote the question, I was thinking about procedures that could be in place to avoid the flags but also to allow a leader to know problems exist. With the stresses of a leader's life, avoiding the nagging feeling that something could be missing takes it toll. I like Chad's suggestions below. They are helpful. I believe having other ongoing processes or groups in place to survey, analyze and assess conditions and potential problems may also be helpful. Being sure relationships are strong and people feel safe to discuss concerns will also avoid that nagging feeling. I am sure there are many other ideas.
