A Software Product Line (SPL) is a collection of related software products that share common features and are developed from a set of core assets. This approach allows organizations to efficiently create multiple software variations tailored to different customer needs while minimizing redundancy in development efforts. By leveraging reusable components, an SPL can significantly reduce time-to-market and development costs. It promotes consistency across products, making maintenance and updates easier. Companies often use feature modeling to define the variations and commonalities within the product line, ensuring a structured and systematic development process.
