There are three basic models of church planting. Each one is designed for a specific purpose; to reach a specific group of people; and to become sustainable in it's own way. The Congregational model includes a full-time pastor and seeks to establish a fully self-supporting church within 3-5 years. The Mission Outpost model focuses on developing a mission outpost among unreached people, those who have special needs, or those who live in an under-resources area. These churches take much longer to become sustainable and may need outside support and funding for many years. The Micro-Church model is a lightweight and low maintenance model of church. These churches have no building, budget or staff and often meet in homes, business, parks or hotel rooms. They are focused on reaching people within their unique context.
