Imagine you run a web development agency and you have lot of clients to cater your services, each client brings with different problem statement, requirements, scope and other specifications. All of these things should be properly documented and this document is called as Product Requirements Documents.
The PRD consists of
Objective or Purpose
Scope
Features and Requirements
User stories or Use case
Technical Requirements
Design Requirements
Success Metrics
Timeline
I will explain all of the terminologies with an example it will give you a better understanding.
Lets us assume that you are building To-Do application, a to-do application is just like a task tracker which tracks al of your work although it has variations we will go with the basic one.
1. Objective or Purpose
It is a starting point of PRD it gives the main purpose for creating the product, what the problem is being solved.
- Build a comprehensive to-do web application for individual users to track their tasks, schedule reminders, and monitor task progress (in progress, pending, completed).
- Provide an intuitive and user-friendly interface to help users stay organized and productive.
2. Scope
It describes boundaries of the project what is included and what is not included in the project or product, this ensures alignment between customers and stakeholders about product functionality.
What is in Scope
Building a fully functional to-do application.
Active reminders with notifications (email and/or push notifications).
Visual task progress tracking (e.g., through color codes or progress bars).
What is not in Scope
No AI or machine learning features.
Not designed for team task management or collaboration.
3. Features and Requirements
Lists the specific functionalities the product will have and the technical requirements needed to deliver them. It has 2 types P1 and P2.
P1 - Functionalities under this, are the one which are must and should be included in the product.
P2 - Under this the functionalities are good to have not mandatory.
P1: (Must have features)
Task creation, deletion, edit, update.
Visual indicators of each tasks (Pending, Completed, Progress).
Active remainders via email or SMS.
Sorting and prioritization of tasks.
P2: (Nice-to-Have Features)
AI-generated summaries of daily tasks.
Tagging tasks with user-defined categories for better organization.
Image upload functionality to attach relevant images to tasks.
User Stories or Use Cases
Use case or User stories are just like requirements from the user perspective side, its just like user narrating a problem statement, I have listed down below you will get to understand about this.
"As a user, I want to create, edit, and delete tasks so that I can manage my responsibilities efficiently."
"As a user, I want to organize tasks by priority and due date so that I can focus on the most urgent ones."
"As a user, I want to receive reminders for important tasks so that I don’t miss any deadlines."
"As a user, I want to mark tasks as completed so that I can track my progress over time."
Technical Requirements
Well we have the requirements collected now its time to build the product, but how do we build the product therefore based on the requirement and analysis the tech stack is chosen.
Frontend: ReactJS (for building an intuitive and responsive user interface).
Backend: NodeJS and ExpressJS (to handle API requests and server logic).
Database: MongoDB (for storing user tasks and progress).
Job Queue: BullMQ and Redis (to handle reminders and background jobs).
Containerization: Docker (to ensure smooth deployment across environments).
Deployment: Vercel (for hosting the frontend) and AWS/Render (for backend deployment).
Design Metrics
In design metrics here its about UI/UX, color of logo well not just about UI/UX beyond UI/UX like branding, marketing, performance and more.
Theme: Blue and white color scheme for a clean and professional look.
Font: Roboto (modern and easy-to-read).
UI:
Intuitive navigation with a floating “Add Task” button.
Task cards displaying the title, status, due date, and reminder toggle.
Progress bar or color-coded statuses for tracking completion.
Accessibility: Ensure WCAG-compliant contrast ratios for colorblind users.
Success Metrics
Identifies measurable goals to evaluate the product's success post-launch. These could be business metrics, technical metrics, or user feedback metrics.
User Engagement:
Achieve 500 active users within the first month.
Maintain a retention rate of 80% over three months.
Performance:
Reminders sent with 99.9% accuracy and under 5 seconds delay.
Handle up to 10,000 tasks per user without performance issues.
User Satisfaction:
- 4.5+ average rating on feedback surveys.
Timeline
Week 1–2: Requirements gathering and design mockups.
Week 3–5: Backend development (APIs, database schema, job queue integration).
Week 6–8: Frontend development (ReactJS UI, task management features).
Week 9–10: Testing (unit tests, integration tests, performance tests).
Week 11: Deployment and user onboarding.
Week 12: Post-launch monitoring and optimizations.
Conclusion:
“PRD is a document which helps developers, product leads and other teams in the organization to keep track of progress and avoid misalignment between the stakeholders and the team.“
