I created a detailed site map, outlining all potential functionalities for each entity. The mapping was divided into four sections, which were then pieced together to identify interactions and interdependencies. This exercise significantly simplified the system’s structure.

Entity 1 : Charging Management System (CMS)

Entity 2 : Charge Point(CP)

Entity 3 : User Mobile App

Entity 4 : Electric Vehicle(EV)

The image visually represents how different entities and their functions interact, using color coding to distinguish them. This structured approach helped in defining the information architecture by mapping relationships, identifying dependencies, and ensuring a well-organized system.

Based on this study, a final site map was formulated
