All about a PRD - Product Requirement Document.

As soon as we get to know about the PM world, next question is 'What is a PRD?'. So to simplify it here is my understanding for a PRD.



Creating a powerful Product Requirements Document (PRD) is one of the most critical steps in product development. A PRD translates your product vision into a clear roadmap that guides your development team as well as the stakeholders and ultimately lead to a successful product. Below are all the key elements that make a comprehensive PRD, with an illustrative example.


  • Title: Begin with a short, clear title that accurately reflects the product or feature.

  • Purpose: State the main problem your product is designed to solve and how it brings value to the user.

  • Background: Provide context, such as the market analysis, customer feedback, or strategic rationale that has led to this initiative.

  • Objectives: List the business and user objectives. Define what success looks like.

  • Target Audience: Detail your primary and secondary user personas, their needs, and how the product meets those needs.

  • User Stories and Scenarios: Provide user stories to show how different personas will interact with your product.

  • Features and Requirements: Breakdown of the product's features, both functional (what the product does) and non-functional (performance, scalability, etc.). This section should be very detailed.

  • Wireframes: These are simple visual representations of the user interface. They don't need to be high-fidelity at this stage but should give a clear idea of the user journey.

  • Constraints: Highlight any limitations or restrictions such as technology stack, regulations, or budget.

  • Dependencies: Identify dependencies on other teams, systems, or projects.

  • Hypothesis formation: Hypothesis formation is an important part of the product development process. It's a statement that you believe to be true and can be tested to validate its accuracy. In the context of a PRD, hypothesis formation typically revolves around user behavior, the value of a particular feature, or a product's impact on a given business metric.

  • Assumptions: List any assumptions made while writing the PRD.

  • Performance and Success Metrics: Defining KPI and what success looks like is essential for both the team and stakeholders. These can be quantitative or qualitative.

  • Release Plan: This is your high-level timeline, taking into account any dependencies and milestones.


Let's consider an example of a "Smart Home Security App".



Title: Smart Home Security App - Door Lock Feature

  • Purpose: To provide users with the ability to lock/unlock their homes remotely for added convenience and safety.

  • Background: Market research indicates a growing demand for smart home security solutions.

  • Objectives: Increase user base by 15%, reduce instances of home break-ins among our users by 30%.

  • Target Audience: Homeowners, particularly those who travel frequently. Or home owners who have children or elderly at home.

  • User Stories and Scenarios:

  1. "As a user, I want to check if my doors are locked when I'm not home." "As a user, I want to remotely unlock my door when my kids forget their keys."

  2. "As a homeowner, I want to receive real-time notifications when my door is locked or unlocked, so that I can stay informed about the security status of my home."

  3. "As a user, I want the app to automatically lock my doors at a specific time each night, so that I don't have to remember to do it myself."

  4. "As a homeowner, I want to grant temporary access to guests by generating a time-bound virtual key, so I can provide access without compromising my home's security."

  5. "As a user, I want to view a history of locking/unlocking activities, so I can track who has accessed my home and when."

  6. "As a parent, I want to receive a notification if the door remains unlocked for an extended period of time, so I can ensure the safety of my children."

  7. "As a user, I want the option to manually override the smart lock through the app, in case of technical issues or emergencies."

  • Features and Requirements: Secure sign-in, real-time door lock status, remote lock/unlock capability, activity log, notifications, etc.

  • Wireframes: [Here, imagine a wireframe image of the app showing the sign-in page, the main page with lock/unlock feature, notifications, and temporary key creation page.]

  • Constraints: Must comply with data privacy laws, needs to be compatible with various smart lock brands.

  • Dependencies: Requires integration with hardware team and cooperation of smart lock manufacturers.

  • Hypothesis & Validation:

Hypothesis 1: "By introducing the remote door lock/unlock feature, we believe we can increase user engagement with the app by 30%."

Hypothesis 2: "Implementing real-time notifications for locking/unlocking activities will enhance users' sense of security and increase app retention rates by 20%."

Hypothesis 3: "By offering a feature that generates temporary, time-bound virtual keys, we expect to see a 15% rise in user acquisition, as this feature would be particularly appealing to homeowners who frequently have guests."

  • Assumptions: Users have compatible smart locks and smartphones.

  • Performance and Success Metrics:

A 30% increase in daily active users after three months of launching the new feature.

User engagement with the lock/unlock feature at least twice a day.

At least 20% of users creating temporary, time-bound virtual keys on a weekly basis.

Positive user feedback on the enhanced security and convenience.

  • Release Plan:

Product Planning: 1 month

Development: 3 months (includes integration with various smart lock brands)

User Acceptance Testing: 2 weeks

Beta Release: 1 month (small group of users for live feedback)

Full Launch: Roll out in phases over 2 months


Including these elements in your PRD ensures that the entire team is on the same page about the product's design, functionality, and goals, thereby ensuring a smoother product development journey.

An organization may choose to include some other points or exclude a few from above as per their requirement. There is no hard and fast rule that it has to be a particular way.

Remember, your PRD is a living document and should be updated as things evolve based on user feedback, business needs, and market changes.
