They listen to people in other organizations for ideas. However, good leaders avoid copying. The assumption that what works will work anywhere is not valid. The church is a system of processes working together toward a common aim. The entire denomination is a system, and each congregation is a system.
All parts are important in a system.
In an airplane, the bolts that fasten the wings to the plane are as important as the wings themselves. In a congregation, the Sunday school teacher is as important as the curriculum materials he or she uses to teach. A system is designed for the results it is getting. If we want different results, we have to redesign the system. We can't redesign it initially at the general church level because there is no leader to lead the change.
