Neutrosophic Likert Scale to Assess the User Satisfaction with Retail Software Developed by Software Engineering Students

Abstract

This study aimed to evaluate user satisfaction with retail software developed by Software Engineering students using a Neutrosophic Likert Scale, which captures agreement, indeterminacy, and disagreement dimensions to better reflect real-world user perceptions. The results demonstrated high agreement scores (mean ∼0.75) across key characteristics such as ease of use, speed, and response quality, indicating strong user satisfaction, while moderate indeterminacy scores (mean ∼0.25–0.75) highlighted areas for minor improvements. The study’s key contributions include the application of neutrosophic logic to assess software usability, validation of the student’s technical and managerial competencies, and actionable insights for enhancing system performance and user experience.
