Ohjelmistotuotelinja, often translated as "software product line," is a software development approach focused on creating a family of related software systems. Instead of developing each system independently, a software product line leverages a set of common, reusable assets. These assets can include software components, documentation, test cases, and development processes. The goal is to systematically manage the diversity and commonality among a set of products to achieve increased productivity, higher quality, and reduced time-to-market.

The core idea behind a software product line is to identify and manage the variability and commonality within a domain. Commonality refers to features or components shared across multiple products in the line, while variability represents features that differ between products. By abstracting these commonalities and providing mechanisms to manage variability, developers can efficiently configure and build new products based on the established foundation.

Key concepts in software product line engineering include domain analysis, which identifies the core domain and its requirements, and system configuration, where specific products are assembled from the reusable assets by selecting and customizing variable features. This approach often involves a dedicated process for managing the product line, including strategies for asset development, integration, and evolution. It contrasts with traditional software development, where each project might start from scratch or with limited reuse. The benefits of adopting a software product line approach are most pronounced when developing a significant number of related software systems over an extended period.
