This document, within the context of methods and tools for supporting explicit and/or separate
variability modelling, variability model management and variability model support in software and
systems product lines:
— provides the terms and definitions specific to variability modelling for software and systems
product line;
— defines processes for variability modelling, variability model management and variability model
support throughout the product line lifecycle. 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 that automate or semi-automate tasks and methods.
This document does not concern processes and capabilities of tools and methods for a single system but
rather deals with those for a family of products.
