As church planter enters a new region, the question is, where to begin? In the early years of mission work, missionaries evangelized from village to village and then focused church-planting efforts on those locations where people were most receptive to the Gospel. This approach is in keeping with the harvest priority principle. The strategic beachhead approach seeks to establish a spiritual foothold in several political, commercial, or educational centers. Cluster church planting is opposite to the strategic beachhead approach: the initial goal is to plant several churches in a more limited geographical area.  In this section of the lecture about regional strategies Craig Ott discusses strengths and weaknesses of these approaches.
