Basically all companies today go beyond the development of single products and offer set(s) of similar and related products. In marketing, one such set is often called a product line. Nevertheless, still today most products are not yet engineered as product lines, i.e., they are not yet derived from a single platform. In this paper, we explore the relation of these two forms of product lines. It is shown that under certain circumstances engineered and marketed software product line subsume different products. This paper shows how these two perspectives differ and why a difference in products between these perspectives may be appropriate from a company perspective. Finally, it is argued that activities currently subsumed under product management and scoping should be closely coordinated, allowing companies to optimize their product portfolios since decision-making is facilitated.
