Congregations seeking to transform discover why people stay and are active in their congregation. They are as concerned about this as they are about why people leave. They see people leaving and become appropriately anxious, but not overly anxious.
They know that many articles are being written on why people leave. Particularly we are in a period where people are concerned about why the Millennial generation is leaving. Congregations seeking to transform conduct exit interviews with willing people so they can improve how they serve people.
They also conduct stay interviews to see why people stay in their congregation.
