Product family is a concept used in product management and systems engineering to describe a group of related products that share a common platform, architecture, or set of assets and are designed to address related customer needs. Members of a product family typically reuse core components such as hardware modules, software libraries, design patterns, manufacturing processes, and branding. The approach aims to achieve economies of scale, faster development, and consistent user experiences across products.

A product family is organized around a shared platform that provides a common set of features, interfaces, and constraints. Individual products, or variants within the family, differ in optional features, configurations, or target markets while remaining compatible with the platform. Distinguishing between a product family, a product line, and a product platform helps clarify scope: the platform is the reusable basis; the family is the set of related products; and the line refers to the collection of products offered to customers.

Lifecycle management for a product family involves platform engineering, product development, and continuous evolution. Domain engineering creates reusable assets and architectures, while application engineering tailors products to specific requirements. Governance ensures clear decision rights on reuse, variability, and product closure.

Benefits include reduced development and manufacturing costs, shorter time to market, improved quality through shared components, and easier maintenance. Challenges involve managing variability, avoiding platform drift, balancing reuse with product differentiation, and coordinating across disciplines. Metrics often focus on reuse rate, time-to-market, total cost of ownership, and cross-product quality. Examples appear across software, consumer electronics, automotive, and industrial equipment sectors.
