Nonetheless, a compelling case can be made for adopting a product line approach because it addresses a problem facing many program managers today's how to cost-effectively acquire, develop, and maintain a set of related software-intensive systems and how to respond to the needs of greater product agility in the face of the current DoD transformation.

This technical note chronicles the decisions a program manager might face in considering the adoption of a product line approach. This report uses a hypothetical acquisition to focus on why an acquisition organization should consider adopting a product line approach ?"instead of the traditional stovepipe approach ?"when acquiring a number of software-intensive systems that have a lot in common.
