Does a system-of-systems (SoS) context rule out the use of software product lines?
No. On the contrary, software product lines can help reduce the complexity of an SoS context. An SoS comprises independent, self-contained systems that, when taken as a whole, satisfy a specified need. Many software-intensive contexts today are SoSs. The complexity involved can be daunting. However, in many cases, there is considerable commonality among some of the self-contained systems. Suppose, for example, that the SoS involves 200 separate systems that must all interoperate. But suppose further (as is often the case) that there are some clusters within those 200 that have considerable commonality and whose variations could be handled economically. By making those clusters into software product lines, you can tame the interoperability issue into a smaller, more manageable set of interfaces and thereby reduce the complexity of the SoS. Moreover, the economic advantages and predictability associated with software product lines will be highly beneficial to the SoS in question.
