Functional Specification Document (FSD)

1. Document Information

  • Title: Name of the web application (e.g., "Task Management Web App FSD").
  • Version: Version number of the document (e.g., v1.0).
  • Author(s): Names and roles of contributors (e.g., product manager, lead developer).
  • Date: Creation or revision date (e.g., September 1, 2025).
  • Approval: List of stakeholders who must review/approve the document.
  • Change History: A table tracking document revisions, including version, date, and changes made.

2. Introduction

  • Purpose: Brief explanation of the FSD’s goal (e.g., to define technical requirements for building the web app).
  • Scope: Overview of what the web app will do and its boundaries (e.g., "A task management app for teams to assign, track, and complete tasks, excluding invoicing features").
  • Audience: Who the document is for (e.g., developers, designers, QA team, stakeholders).
  • Definitions and Acronyms: Key terms (e.g., API, UI, UX) and project-specific jargon.

3. System Overview

  • App Description: High-level summary of the web app’s purpose and value (e.g., "A cloud-based platform to streamline team task collaboration").
  • Objectives: Specific goals (e.g., improve team productivity, reduce task tracking errors).
  • System Architecture: Overview of the technical structure (e.g., frontend in React, backend in Node.js, MongoDB database).
  • Key Features: List of core functionalities (e.g., user authentication, task creation, notifications).

4. Functional Requirements

  • Feature Breakdown: Detailed description of each feature, typically organized by module or user flow. For each feature:
    • Feature Name: (e.g., "User Authentication").
    • Description: What the feature does (e.g., "Allows users to register, log in, and reset passwords").
    • Inputs: Data or user actions required (e.g., email, password).
    • Outputs: Expected results (e.g., successful login redirects to dashboard).
    • User Interface: Description of UI elements (e.g., login form with email and password fields).
    • Dependencies: Other features or systems required (e.g., email service for password reset).
  • User Roles and Permissions: Define roles (e.g., admin, team member) and their access levels (e.g., admins can delete tasks, users cannot).
  • Workflows: Step-by-step user or system processes (e.g., "User submits task → System assigns task ID → Notification sent to assignee").

5. Non-Functional Requirements

  • Performance: Expected response times (e.g., page load under 2 seconds).
  • Scalability: Capacity to handle users (e.g., support 1,000 concurrent users).
  • Security: Measures like encryption, authentication protocols (e.g., OAuth 2.0, HTTPS).
  • Usability: Accessibility standards (e.g., WCAG 2.1 compliance).
  • Reliability: Uptime requirements (e.g., 99.9% availability).
  • Compatibility: Supported browsers/devices (e.g., Chrome, Firefox, mobile responsive).

6. Technical Specifications

  • Frontend: Frameworks, libraries, or tools (e.g., React, Tailwind CSS).
  • Backend: Server-side tech (e.g., Node.js, Express, REST API).
  • Database: Structure and type (e.g., MongoDB with collections for users, tasks).
  • APIs: Internal/external APIs, including endpoints (e.g., POST /api/tasks for task creation).
  • Hosting/Deployment: Cloud provider or server setup (e.g., AWS, Docker).
  • Data Models: Schema descriptions (e.g., Task: {id, title, assignee, due_date}).

7. User Interface and Experience

  • Wireframes/Mockups: Reference to attached or linked UI designs (e.g., Figma links).
  • Navigation Flow: How users move through the app (e.g., homepage → task list → task details).
  • Error Handling: How errors are displayed (e.g., "Invalid email" alert on login failure).

8. Assumptions and Constraints

  • Assumptions: Conditions assumed to be true (e.g., users have stable internet).
  • Constraints: Limitations (e.g., budget, timeline, or tech stack restrictions).

9. Testing Requirements

  • Unit Testing: Components to test (e.g., API endpoints, UI components).
  • Integration Testing: How systems interact (e.g., frontend-backend communication).
  • User Acceptance Testing (UAT): Criteria for user approval (e.g., task creation works as expected).
  • Tools: Testing frameworks (e.g., Jest, Cypress).

10. Implementation Plan

  • Timeline: Milestones and deadlines (e.g., MVP completion by Q4 2025).
  • Resources: Team roles (e.g., 2 frontend developers, 1 backend developer).
  • Risks: Potential issues and mitigation (e.g., "API downtime risk: implement fallback").

11. Appendices

  • Glossary: Additional terms or acronyms.
  • References: Related documents (e.g., PRD, wireframes).
  • Diagrams: System architecture, data flow, or ERD (entity-relationship diagram).
  • Mockup Links: External links to designs or prototypes.
