I also would focus more on the Christian discipline of prayer and meditation. I have found out that prayer is very essential to the life of the church. We talk it but do very little of it, except for Aunt Bessie's toe. In Missouri, the percentages are very high for forced terminations having roots in people skills and leadership skills. I am not a grad of seminary but have extensive counseling training.
People skills are paramount to success.
To some degree we're evaluating almost constantly, more in an informal way. You can't wait for an annual event to evaluate. We have used evaluations with great success. Most of the time, we simply evaluate honestly among the staff. Annually the ministry is evaluated at budget time but the ongoing evaluation is the most important.
