Mobile software developers must deliver systems faster and at lower cost, while improving reliability and performance.

With content being the main selling point developers can't continue to provide one-size-fits-all solutions.

Demand for product differentiation comes from several sources and complicates development even further:

• Differences between handsets
• Operator-specific requirements
• Market differentiation e.g. high-end vs. low-end products
• Legal differences

Traditional approaches to address differentiation such as modifying copied files (clone-and-own), configuration-management branching, language-level constructs such as if-defs, special file-names, and build and / or installer scripts don't scale well.

Software Product Lines offer a scalable solution to product differentiation.

In Software Product Lines, individual product variants are built from a set of reusable, configurable components using a flexible assembly process.

Software Product Lines scale well because most of the functionality of each new product has already been implemented in the reusable software components.
