Refining the ISO 9126 Model for Enhanced Decision Support System Evaluation in the Manufacturing Industry

Abstract

In the increasingly competitive landscape of the manufacturing industry, leveraging advancements in information technology has become pivotal for gaining a competitive edge. Specifically, the furniture manufacturing industry has adopted decision support systems (DSS) to meet diverse information needs. However, user concerns regarding these systems, including information reporting speed, order reception, and the accuracy of raw material usage calculations, persist. The development of any system necessitates the application of quality assurance standards that align with user requirements. In light of these concerns, the measurement of software quality emerges as an essential strategy to assuage user doubts about the DSS. Employing the ISO 9126 standard as an assessment parameter provides a reliable framework for evaluating the quality of the DSS. Although the ISO 9126 model possesses several characteristics, this study focuses exclusively on two: functionality and reliability. The anticipated outcome of this research is a refined understanding of user satisfaction pertaining to the implementation of the DSS. Consequently, this study's findings may contribute to the DSS's credibility, specifically concerning the speed of reporting, order reception, and the precision of raw material usage calculation. This, in turn, can influence the decision-making process in production, thereby enhancing the overall effectiveness of the manufacturing industry.
