GB/T 45804-2025 Software and systems engineering—Tools and methods for product line requirements engineering

Scope

This document focuses on the processes and capabilities of requirement engineering for software and system product lines, as well as related member products, within the scope of tools and methods for requirement engineering of software and system product lines.
—— Provides specific terminology and definitions for requirement engineering of software and system product lines and related member products;
—— Defines process groups and the processes executed in product line requirement engineering (these processes are described according to their purpose, inputs, tasks, and outputs);
—— Defines methodological capabilities to support the definition tasks of each process;
—— Defines tool capabilities to automate or semi-automate tasks or defined methodological capabilities.
This document focuses on the processes and capabilities of requirement tools and methods for product families rather than single systems.
This document is not applicable to physical products. System-level products and software lifecycle products, such as requirement documents, architecture data, verification plans, behavioral models, etc., are generated using the methods and tools described in this document. For system software components, this document is applicable to handling system elements of the product line and software elements used in the product line (if any). Product line processes are recursive across different levels of products.
Note: This document is applicable to system, software, or service series.
