Olfa Djebbi (CRI), Camille Salinesi (CRI), Daniel Diaz (CRI)
TL;DR
The paper introduces RED-PL, a user-oriented, systematic method for deriving product requirements in software product lines, validated through industrial case studies to enhance decision-making during requirements elicitation.
Contribution
It presents a novel, interactive approach that guides requirements derivation as a decision-making process, addressing a gap in existing variability modeling methods.
Findings
Validated in an industrial blood analyzer product line
Supports systematic and interactive requirements elicitation
Enhances decision-making in requirements derivation
Abstract
Product lines (PL) modeling have proven to be an effective approach to reuse in software development.Several variability approaches were developed to plan requirements reuse, but only little of them actuallyaddress the issue of deriving product requirements.This paper presents a method, RED-PL that intends to support requirements derivation. The originality ofthe proposed approach is that (i) it is user-oriented, (ii) it guides product requirements elicitation andderivation as a decision making activity, and (iii) it provides systematic and interactive guidance assistinganalysts in taking decisions about requirements. The RED-PL methodological process was validatedin an industrial setting by considering the requirement engineering phase of a product line of blood analyzers.
