Product line architecture refers to a structured framework that enables the development of a range of related products from a common set of core assets. This approach allows organizations to efficiently manage variations and customizations while maintaining consistency across the product line. By defining reusable components and shared features, companies can reduce development time and costs. In a product line architecture, key decisions are made regarding the commonalities and differences among products. This includes identifying shared functionalities, interfaces, and design patterns. Such a strategy not only enhances collaboration among teams but also improves the overall quality and reliability of the products offered.
