Challenges in Early Verification and Validation of System Requirements

Abstract

Today, requirements engineering (RE) is a key process in the development of complex systems-(ISO/IEC/IEEE 2015). Requirements containing quality issues such as ambiguity or inconsistency can lead to late error detection in systems design, resulting in high project cost overruns. This paper presents challenges for early system requirements verification and validation associated to an executable model-based requirements engineering (eMBRE) process proposal.
