2 Project Overview

2.1 What Are We Building

2.1.1 System Function

An e-commerce mobile application for users to browse products, manage a shopping cart, and complete purchases.

2.1.2 Users

• Customer / Shopper

2.1.3 Problem Solved

The application aims to provide a stable e-commerce experience but currently suffers from critical failures in core user journeys, including user registration and order checkout. It also has significant UI/UX issues with notifications, language settings, and dark mode that degrade user trust and usability.

2.1.4 Key Success Metric

Increase the Overall Test Pass Percentage from 83.33% to over 98% by fixing all major and critical defects.

2.2 Scope

2.2.1 In Scope

• User Authentication (Login, Logout, Registration)
• Dark Mode functionality
• Push Notifications
• Displaying time accurately within the app
• Terms of Use and Privacy Policy review
• Language settings
• Viewing Orders
• Shopping Cart Management (Add, Update, Remove items)
• Product Catalog and Search
• Checkout Process

2.2.2 Out Of Scope

• In-app calls to sellers
• Price bargaining / 'Make an offer' feature
• Expanded product details (color, brand name)
• Direct customer feedback forms
• FAQ section
• Video guides for buying and selling

FT-CART-CHECKOUT	Complete a purchase after providing my details	Finalize my purchase and receive confirmation that my order has been accepted.	Must	The checkout flow must allow users to select delivery or pickup and successfully place an order. Payment processing is out-of-scope and handled externally (e.g., Cash on Delivery).
FT-ORDER-NOTF	Receive notifications about my orders	Track the progress of my purchase from confirmation to delivery.	Must	This requirement covers both push notifications (see FT-APP-NOTIFY) and in-app status updates for orders.
