ConcernLines: A timeline view of co-occurring concerns

ConcernLines supports the cognitive process of understanding software evolution by visualizing co-occurring concerns over time. Understanding the evolution of a software system requires understanding how information about the release history, non-functional requirements and project milestones relates to functional requirements of the software components. ConcernLines presents a timeline view of all these concerns and allows the identification of co-occurrences. Currently, the tool exists as Web Application developed in Adobe’s Flex.

ConcernLines was developed with support from IBM Centers for Advanced Studies - Ottawa.
