Abstract

The study employed an Agile-based system development approach supported by Unified Modeling Language (UML). Functional validation was conducted using black-box testing to ensure system conformity with user requirements. Usability evaluation was performed using the System Usability Scale (SUS) after the system had been used operationally for three months by 25 respondents representing various user roles. Parental engagement was measured using an adapted instrument contextualized to the use of a daycare information system. The results showed that the system achieved a SUS score of 82, which falls into the Good and acceptable category, while the mean parental engagement score reached 4.37, indicating a high level of engagement. These findings suggest that the system provides a good level of usability and is capable of supporting active parental participation in monitoring children’s development. The scientific contribution of this study lies in providing an integrated evaluation framework that combines Agile-based development, standardized usability measurement, and user engagement analysis within a real operational context. This study extends usability research beyond technical interface evaluation toward understanding user engagement within digital information service systems.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) in the culinary sector often face challenges in managing sales transactions and business data due to fragmented and manual operational processes. This condition hinders data integration and information transparency, which are essential for effective business monitoring. This study aims to develop an Integrated Sales and Business Management System (ISBMS) as an integrated information system that unifies sales operations and business management within a single platform. This research adopts the Design Science Research (DSR) methodology by implementing a layered architecture approach to ensure system modularity and scalability. The developed system integrates the functions of a Transaction Processing System (TPS), Management Information System (MIS), and Decision Support System (DSS) at the descriptive analytics level, along with a digital product catalog module as part of the e-commerce functionality. Usability evaluation was conducted using the System Usability Scale (SUS) involving 10 respondents consisting of business owners and operational staff. The results indicate that ISBMS achieved an average SUS score of 80.4, which falls within the “Good” to “Excellent” category with an “Acceptable” level of acceptability. These findings demonstrate that an integrated system approach can improve data consistency and business information visibility in a more structured manner, while also contributing to the development of an information system architecture model that is relevant to MSME operational needs.
