Visualising Product Line Requirement Selection Decision Inter-dependencies

A software product line is defined as a set of software products sharing a set of common features but containing significant variability. Mature software product lines generate a large number of variable requirements and complex inter-dependencies between them. A significant challenge is to provide engineers with clear and understandable views of these inter-dependencies and their impact. This paper presents a visualisation meta-model for representing inter-dependencies between product line and describes a tool to realise these visualisations.
