A web-based monitoring system application was created with Laravel as the backend, following the steps of the System Development Life Cycle (SDLC) waterfall method, and using the Unified Modeling Language (UML) as a visualization tool for system requirements through Use case Diagrams and Activity Diagrams in order to increase efficiency and lower the risk of delays in contract document management. This program has real-time dashboards, data search, upload files, and automatic alerting capabilities. The system performed effectively in enhancing labor productivity, recording accuracy, and procurement process transparency, according to test results utilizing the black box testing method and interviews based on the Technology Acceptance Model (TAM).
