A history of the international requirements engineering conference (RE)RE@21

This paper traces the history of the International Requirements Engineering Conference from its beginnings as the International Symposium on Requirements Engineering and the International Conference on Requirements Engineering. The history is tracked to the present, with suggestions for future considerations, such as more emphasis on systems requirements engineering, and enhanced practitioner participation. Other requirements engineering events and activities are also discussed. A timeline of major milestones is included, along with a brief discussion of requirements engineering research activities that occurred in parallel with the conference.
