Defines, within the context of the tools and methods of variability traceability for software and system product lines: - the terms and definitions specific to variability traceability for software and systems product lines; - process groups and their processes for establishing and managing variability traceability at product line lifecycle processes. Those processes are described in terms of purpose, inputs, tasks, and outcomes; - method capabilities to support the defined tasks of each process; - tool capabilities to automate/semi-automate tasks or defined method capabilities.

This International Standard, within the context of the tools and methods of variability traceability for software and system product lines: ― provides the terms and definitions specific to variability traceability for software and systems product lines; ― defines process groups and their processes for establishing and managing variability traceability at product line lifecycle processes. Those processes are described in terms of purpose, inputs, tasks, and outcomes; ― defines method capabilities to support the defined tasks of each process; ― defines tool capabilities to automate/semi-automate tasks or defined method capabilities. This International Standard does not concern processes and capabilities of tools and methods for a single system but rather deals with those for a family of products.
