Background & Context
This academic project was developed for the Information Systems Analysis and Design course (ISYS6677003) as part of the system modeling and analysis module.
The case study, Alerty, represents a mobile application designed to streamline access to emergency services and social incident reporting. Many citizens experience difficulties in contacting emergency numbers or reporting urgent situations quickly. Alerty aims to address this issue by offering a centralized, easy-to-use platform for contacting authorities and submitting reports directly through mobile devices.
Project Objective
To design a complete system analysis and design model for the Alerty mobile application, demonstrating the ability to translate business needs into structured system documentation using industry-standard modeling tools.
Project Scope & Deliverables
System Analysis Deliverables
