System Requirements Document (SRD)

Project Name: marine-messaging

1. Introduction

The marine-messaging project is designed to provide troop leaders with a robust messaging and email system to facilitate seamless communication within scout troops. This system will enable authorized leadership roles to send formatted emails and announcements to individuals or groups, ensuring effective troop-wide communication. The goal is to deliver a reliable, controlled, and user-friendly communication platform tailored to the needs of scout troops in the United States.

This document outlines the system requirements for marine-messaging, including functional and non-functional requirements, user personas, visual design, technical stack, and other critical aspects.

2. System Overview

The marine-messaging system will serve as a centralized communication platform for scout troops. It will allow troop leaders to send emails, announcements, and automated notifications to scouts, parents, and other leaders. The system will ensure that messaging remains controlled, with permissions restricted to authorized leadership roles. Key features include:

• Role-based permissions for sending mass emails.
• Group messaging capabilities for troop-wide communication.
• Automated notifications and reminders based on troop activities.
• Reliable delivery of important updates.

The system will be tailored to the needs of scout troops in the US, adhering to local timezone defaults (EST/PST) and ensuring compatibility with common devices and platforms.

3. Functional Requirements

• As a Troop Leader, I should be able to send formatted emails to individual scouts, parents, or other leaders.
• As a Troop Leader, I should be able to send announcements to entire groups within the troop.
• As a Troop Leader, I should be able to schedule automated notifications and reminders based on troop activities.
• As a Troop Leader, I should be able to manage permissions to ensure only authorized leaders can send mass emails.
• As a Scout, I should be able to receive notifications and reminders about troop meetings and events.
• As a Parent, I should be able to receive updates and announcements about troop activities.

4. User Personas

Troop Leader

• Role: Authorized leadership role responsible for troop communication.
• Needs: Ability to send emails, announcements, and automated notifications.
• Permissions: Full access to messaging tools and group communication features.

Scout

• Role: Member of the troop.
• Needs: Receive notifications and reminders about meetings and events.
• Permissions: Limited to receiving messages and updates.

Parent

• Role: Guardian of a scout.

• Permissions: Limited to receiving messages and updates.

5. Visuals Colors and Theme

The marine-messaging system will feature a clean and professional design with the following color palette:

• Primary Color: Navy Blue (#001F54) – representing trust and reliability.
• Secondary Color: Seafoam Green (#2E8B57) – symbolizing growth and connection.
• Accent Color: White (#FFFFFF) – for clarity and readability.
• Background Color: Light Gray (#F5F5F5) – ensuring a neutral and calming interface.

The theme will incorporate nautical elements, such as wave patterns and anchor icons, to align with the scout troop's marine identity.

6. Signature Design Concept

Interactive Nautical Dashboard

The homepage of marine-messaging will feature an interactive nautical dashboard that immerses users in a marine-themed environment.

Key Features:

• Dynamic Wave Animation: The background will feature subtle, animated waves that move gently, creating a calming and engaging visual effect.
• Compass Navigation: A clickable compass will serve as the primary navigation tool, allowing users to explore different sections of the platform (e.g., Inbox, Notifications, Settings).
• Message-in-a-Bottle Animation: When a new message arrives, a virtual bottle will "float" onto the screen, accompanied by a subtle sound effect, adding a playful and memorable touch.
• Troop Activity Timeline: A scrollable timeline resembling a nautical map will display upcoming troop activities, reminders, and notifications.

This design will ensure the homepage is both functional and visually captivating, leaving a lasting impression on users.

7. Non-Functional Requirements

• Performance: The system must support up to 1,000 active users simultaneously without performance degradation.
• Reliability: Ensure 99.9% uptime for messaging and notification services.
• Security: Implement role-based access control to prevent unauthorized messaging.
• Scalability: The system should be able to scale to accommodate larger troop sizes and additional features.
• Localization: Default timezone settings to EST/PST, with options for customization.
