Regarding the method: It was the SCRUM methodology, carried out with PHP.v8 and Laravel v9 framework, as well as MySQL Workbench 10.4.25 database; For the mobile, the Xamarin 5.9 development framework was used with the C# language, with 19 user stories stacked in 3 Sprints, executed in 98 days, at the end of which the modules will be provided. To differentiate the hypotheses, the Shapiro Wilk and Kolmogorov-Smirnov-Lilliefors normality tests were used, and inferential statistics were used using the student parametric test for paired data with a significance level of 5%. The research design was pre-experimental. The population was 14 people, the sample for the customer service time indicator was 603 clients, for information search...

The incorporation of web systems results in improved efficiency, process optimization, and greater precision in information management, generating a growing demand. In this context, the focus of this study was directed towards the implementation of web solutions aimed at optimizing the administrative management of bookstores. The SCRUM methodology was chosen as the approach for software development, characterized by its iterative and incremental nature. Thirty user stories were carried out in 3 sprints, executed on different days, each concluding with the successful implementation of a module. The results revealed a notable reduction of 38.51% in the average customer service time, with a positive impact of 61.49%. Information search experienced a significant decrease of 2.30%, with an impact of 97.70%. Additionally, the generation of receipts underwent a reduction of 33.70%, with an impa...
