With current trends towards moving variability from hardware to
software, and given the increasing desire to postpone design decisions as much
as is economically feasible, managing the variability from requirements
elicitation to implementation is becoming a primary business requirement in the
product line engineering process. One of the main challenges in variability
management is the visualization and management of industry size variability
models. In this demonstration, we introduce our CASE tool, MUSA. MUSA is
designed around our work on multiple perspective variability modeling and is
implemented using the state-of-the-art in NUI, multi-touch interfaces, giving it
the power and flexibility to create and manage large-scale variability models
with relative ease
