A framework for scenario evolution

Abstract

We report on a framework for scenario evolution. We have studied, based on a laboratory case study, the evolution of scenarios from elicitation to coding, thus using the requirements baseline in a full cycle. Considering our observations of over a hundred and fifty scenarios we discovered a series of relationships and operations that occurred during the evolution. Our framework is a contribution to better understand scenario evolution and to help the tractability and identification of those actions belonging to the environment and those shared with the software.
