Build a Community Safety Alert System for Lagos Neighbourhoods

In high-density Lagos neighbourhoods, safety threats spread faster than formal responses can follow. Armed robbery, street harassment, and sudden civil unrest affect thousands of residents who have no reliable channel to warn each other or receive updates from local authorities. WhatsApp groups exist but are fragmented, unverified, and chaotic under pressure. The problem is not awareness, it is coordination. Residents often know something is wrong before any official does, but the information stays trapped in small social circles. A system that works across feature phones, low-data conditions, and varying levels of literacy could change that. Your task is to design a community safety alert system for a specific neighbourhood in Lagos. This means: a product strategy document, a user flow diagram, and at least one lo-fi prototype screen or interface mockup. Your design should account for feature phone users (SMS or USSD), language barriers, and the role of trusted community figures such as market women, religious leaders, or landlords as nodes in the network. Good work will show you have spoken to or researched the actual constraints of the chosen neighbourhood. It will explain clearly how false alerts are handled, how the system builds trust over time, and why it is more useful than an existing WhatsApp group. A one-page business model or sustainability plan, even a rough one, will strengthen your submission.
