The implementation of Geographic Information Systems (GIS) in regional investment management requires not only technical functionality but also empirical validation of user acceptance. This study evaluates a GIS-based investment opportunity information system developed for South Lampung Regency using a dual assessment framework integrating Black Box Testing and User Acceptance Testing (UAT). Functional evaluation across 42 structured test cases demonstrated full operational compliance with predefined system specifications. To assess user perception, a Likert-based UAT instrument was administered to 15 stakeholders. Descriptive results indicate a very high level of acceptance (M = 4.82, SD = 0.36), supported by excellent internal reliability (Cronbach’s α = 0.973). Inferential analysis revealed that the mean acceptance score significantly exceeded the benchmark value of 4.00, with a very large practical effect size and a confidence interval entirely above the threshold. By integrating structured functional validation with rigorous statistical evaluation, this study proposes a replicable and methodologically robust framework for assessing GIS-based decision support systems in regional governance. The findings demonstrate that the system is both technically reliable and empirically validated in terms of user acceptance, while highlighting opportunities for further usability refinement and system scalability enhancement.
