—— This study developed a Cross-Platform Alumni Information System for Northern Iloilo State University – Batad Campus. It collects alumni data from BNAVHS-BPC-NIPSC-NISU for official and legal purposes. The system strengthens alumni–university connections, monitors graduates’ career progress, and analyzes employment trends while streamlining communication and transactions related to alumni activities. Guided by Nutley’s (2002) diffusion theory, the study examined how communication channels, social systems, and contextual factors influence adoption and use. The development followed Dinesh Thakur’s Sequential Flow of Prototyping Methodology to ensure efficiency and accuracy. The system, built using MySQL and PHP, was tested with five faculty members, forty-five alumni, and five IT experts. Evaluation used the ISO 25010 quality model, covering functional suitability, performance efficiency, compatibility, usability, reliability, security, and maintainability. All characteristics received an “excellent” rating, confirming the system’s effectiveness. Core features include alumni registration, profile management, job postings, event updates, forums, and multimedia galleries, with administrative tools for approving members, generating reports, and managing content. Results show the system addresses challenges in alumni tracking, career monitoring, and event coordination. It reduces manual workload, provides real-time data updates, and supports institutional needs for accreditation and curriculum evaluation. By centralizing communication and information management, it fosters stronger alumni engagement and contributes to the university’s strategic growth.
