Metrics for measuring the consistencies of requirements with objectives and constraints

초록

Requirements engineering (RE) is essential to succeed in software projects. That is, it is important to elicit sound requirements for proper performing of RE. If some requirements are inconsistent with a given objectives and constraints, these requirements may hinder the performance of RE. For this reason, it is necessary to pre-check the consistency of requirements. We propose the metrics for evaluating requirements by considering given objectives and constraints. Our metrics are validated by two sample scenarios: "Payroll and Roster Planning of Hospital" and "Noise Source Location System." At the result, we expect that these metrics would be helpful when selecting a set of consistent requirements.
