Understanding and Supporting Large-Scale Requirements Management

Large market-driven software companies face new challenges in require-ments engineering and management that emerged due to their recent ex-tensive growth. At the same time, the pressure generated by competitors’ and users ’ expectations demands being more competitive, creative and flexible to more quickly respond to a rapidly changing market situation. In the pursuit of staying competitive in this context, new ideas on how to improve the current software engineering practice are requested to help maintaining the engineering efficiency while coping with growing size and complexity of requirements engineering processes and their products. This thesis focuses on understanding and supporting large-scale re-quirements management for developing software products to open mar-kets. In particular, this thesis focuses on the following requirements man-agement activities in the mentioned context, namely: scope management, variability management and requirements consolidation.
