To question the dominanceof the dimensions of service quality using the embryonic HESQUAL model onstudents' satisfaction. Besides, the study will identify the mediating effect ofa department’s commitment and a moderating effect of self-efficacy on therelationship between students’ satisfaction and academic performance. The study was a one-time dimensionaland used a simple random sampling method which is suitable for quantitativestatistical analysis and homogeneous populations in nature. Analysis resultingfrom SmartPLS by using 431 responses from undergraduate and graduate students of public universities inBangladesh. The study found that students arefocused on core educational qualities and physical environmental facilities tobe satisfied. Thoroughly,students' satisfaction has a direct impact on academic performance butsurprisingly no moderating precedence of self-efficacy on the connectionbetween student satisfaction and academic performance was seen. Noticeably, theextension of the HESQUAL model of department commitment finds significant influenceson both satisfaction and academic performance. However, the modified HESQUEL will quantify thequality dimensions in higher education, and its application in this study candepict a greater understanding of the quality dimensions required to beprioritized by university authorities and policymakers.

This research aimed to evaluate the effect of improvement in the logistic issues on the service quality (SQ) dimensions of SMEs operating in Saudi Arabia. The investigation followed a quantitative assessment where SEM modelling was used on primary data collected using a survey questionnaire. The sample comprised of 351 employees belonging to different industries and different cities of Saudi Arabia, Jeddah, Khobar, Dammam, and Riyadh. The research identified quality logistics personnel, inventory management, and high technology cost as critical issues in Saudi SMEs. In this research, three SQ dimensions were considered, including assurance, reliability, and responsiveness. The results inferred that the overall effect of improvement in logistic issues was significant on the SQ dimensions. However, the study was limited to Saudi SMEs and three aspects of topics and three dimensions of SQ only. Considering this, the findings of the study have both practical and theoretical implications for SMEs, academicians, and practitioners.
