A beachhead strategy involves launching a new product in a specific, targeted market segment initially and, upon achieving penetration and success in this segment, gradually expanding to additional segments. This approach allows the product manager to focus resources and efforts on a defined group, ensuring a strong market presence and learning from initial market reactions before broader roll-out. This strategy minimizes risk and maximizes impact by building a solid foundation before expanding. References: Moore, G. A. (1991).
