ISO/IEC 26559:2017, 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.
ISO/IEC 26559:2017 does not concern processes and capabilities of tools and methods for a single system but rather deals with those for a family of products.
