From requirements engineering to green requirements engineering

Abstract

After business analysis and software economics lay the foundation, requirements engineering structures the phase of eliciting, analysing, specifying and verifying the objectives and constraints for a software system under development. It is not yet fully investigated how to systematically integrate environmental sustainability into this discipline in order to achieve ‘greener’ software systems. This chapter outlines an approach of how to incorporate environmental sustainability as an objective from the very start in requirements engineering by using a reference artefact model with a goal model and continuous deduction and refinement. Thereby, software engineers are enabled to strategically align the objective of environmental sustainability with the other objectives for the software system under development.
