In terms of purpose, the present research is applied; in terms of method, it is quantitative; and regarding the nature of the data, it is descriptive–survey. The statistical population consisted of all managers and employees of the Agricultural Bank in the northwestern provinces of the country (East Azerbaijan, West Azerbaijan, Ardabil, and Kurdistan), totaling 1,682 individuals. The sample size was estimated at 313 using Cochran’s formula, and the participants were selected through stratified random sampling. The data collection instrument was a researcher-made questionnaire. Research data were analyzed using structural equation modeling with PLS3 and SPSS software. The results indicate that, at a 99% confidence level, there is a positive and significant relationship among the antecedents, components, indicators, and outcomes of service innovation in the Agricultural Bank. Moreover, all indicators demonstrated high explanatory power, and the findings showed that antecedents of professional development, through their influence on developmental components, play a decisive role in shaping professional development outcomes for faculty members. These findings suggest that the proposed service innovation model in the Agricultural Bank possesses appropriate statistical and scientific validity and can be utilized as a practical framework for strategic decision-making by managers and policymakers.</span></p> https://www.journalmbs.com/index.php/jmbs/article/download/78/65
