The management of requirements is an essential element of software development to ensure program success. As software systems become increasingly large, the management of their requirements becomes increasingly challenging. This paper summarizes an approach to software systems requirements management, called "engineering baselines" that has been developed to address those challenges. There are three primary dimensions of those requirements management challenges as addressed by the engineering
