What Is a Product Requirements Document?
A product requirements document is a comprehensive guide that outlines a product’s key features, functionality, and specifications. It serves as a roadmap for the development team, ensuring everyone understands what needs to be built and why.
The PRD provides clear instructions on the product’s goals, target audience, and use cases, helping to keep the project on track and aligned with the original vision. Unlike a static document, you should continuously refine and update a PRD as the project evolves.
PRD example: Imagine a product development company is creating a new wearable device for construction workers that monitors air quality and sends alerts to supervisors. The PRD would detail the device’s sensors, battery life requirements, durability specifications for harsh job sites, and the mobile app interface supervisors use to track worker safety.
The PRD ensures the engineering team, designers, and safety consultants understand exactly what needs to be built and why.
What To Include in a PRD
Creating a comprehensive PRD is all about detailing the various aspects of your product to ensure everyone on the development team is on the same page. Here are the key elements you should include in your PRD:
- Purpose: Start by clearly stating what the new product will do and the problem it aims to solve. This sets the foundation for the entire document.
- Target market: Identify who the product is for. Is it for medical professionals or music producers? Warehouse workers or new parents caring for a baby? Knowing your audience helps tailor the product to their needs.
- Features: Outline the main features the product will offer. Be specific about what the product will do and how it will make things easier or better for users.
- User interaction: Describe how users will interact with the product, including touchpoints, buttons, and displays. This helps ensure a user-friendly design.
- Design and branding: Detail the product’s design and branding. Is it a new look or a rebranding? Consider how the product’s appearance ties into its app or software interface, if applicable.
- Durability: Specify how long the product should last and the environmental conditions it must withstand. Will it need to survive extreme temperatures, water exposure, or heavy use?
- Regulatory requirements: List any certifications or standards the product must meet (e.g., UL, FDA, CE). Be realistic about these requirements to avoid unnecessary costs like spending on certificates that are not actually required.
- Market considerations: Think about where you’ll sell the product and any market-specific requirements. Identify the primary market and any additional markets for future expansion.
- Environmental and safety specifications: Define necessary environmental specifications such as IP ratings, temperature and humidity ranges, and safety considerations. Address factors like fluid and dust ingress, drop ruggedness, and EMI shielding.
- Cost and manufacturing: Discuss cost goals, production methods, and any packaging and shipping constraints. Consider the costs of goods, packaging, shipping, and distribution.
- Servicing and updates: Explain how the product will be serviced. Determine which features are must-haves versus nice-to-haves, and consider future updates based on customer feedback.
- Timeline: Provide a timeline for the product development process, including key milestones and deadlines to keep the project on track.
Remember to keep your PRD under revision control so you can refer back to earlier versions if needed. Each update should be saved as a new revision (Rev 2, Rev 3, Rev 4), making it easy to see the progression and changes over time.
A thorough and well-maintained PRD helps focus the design effort and ensures that the final product meets its intended goals.
How To Write a PRD
Writing a PRD might seem daunting, but breaking it down into manageable steps can make the process much more straightforward. Here’s a step-by-step guide to help you create an effective PRD:
1. Define the Purpose
Start off by articulating why you’re developing the product. This statement should succinctly describe what problem the product aims to solve, what needs it fulfills for its target users, or what strategic goals it supports for the organization.
A well-defined purpose serves as a guiding principle throughout the development lifecycle, ensuring that all subsequent decisions and features align closely with the intended outcome.
Tip: Keep your purpose statement to one or two sentences so anyone on your team can easily remember and repeat it. This clarity helps prevent feature scope creep and keeps everyone focused on the core problem you’re solving.
2. Identify Key Features
Identifying key features is critical for the development of the product. You should clearly describe each feature, include user stories to outline how they will improve safety monitoring, and clarify validation criteria.
Tip: Prioritize features using the MoSCoW method (Must have, Should have, Could have, Won’t have) or something similar to help your team focus on what’s truly essential for the first version of the product.
3. Set Goals and Objectives
Setting goals and objectives in a PRD involves clearly defining the overarching outcomes (goals) the product aims to achieve, such as increasing user engagement or improving functionality, and specifying the measurable, time-bound targets (objectives) that support these goals, like achieving a specific increase in user interaction within a defined period.
This process ensures clarity and alignment with strategic objectives, plus it provides a basis for measuring the success of the product once it’s developed and launched.
Tip: Try SMART goals (specific, measurable, achievable, relevant, time-bound) — a popular method for setting goals and staying on track. This helps your team monitor progress and celebrate wins throughout development.
4. Identify Potential Constraints
Identifying potential constraints means recognizing any factors that could limit or impact the development and implementation of the product.
These constraints could include:
- Technical limitations
- Resource availability (such as budget and manpower)
- Time constraints (deadlines and project timelines)
- Regulatory requirements
- Market conditions
By understanding and documenting these early in the PRD process, teams can proactively address challenges, manage expectations, and make informed decisions to ensure the feasibility and success of the product development cycle.
Tip: Rather than only listing constraints, be proactive by including potential workarounds or mitigation strategies. This approach helps your team prepare for challenges instead of being surprised by them.
5. Create a Timeline
A timeline can include a structured schedule that details key milestones, deadlines, and phases of the product’s development from conception to launch. This timeline serves as a roadmap for the entire project team, specifying when different tasks, such as research or design, should be completed. It also helps coordinate efforts, manage dependencies, and ensure that the project stays on track within the allocated time frame.
Tip: Always plan for unexpected delays. For example, if a feature is expected to take 10 days to complete, adding a 15%-20% buffer would allow an extra 1.5 to 2 days to account for unforeseen challenges. This realistic planning can help maintain team morale and client confidence.
6. Detail Technical Requirements
In this step, you’ll specify the precise technical specifications and functionalities that the product must adhere to. This includes product design (if applicable), software components, programming languages, databases, APIs, security protocols, scalability requirements, and any integrations with existing systems.
It’s crucial to consider performance metrics, data handling requirements, compatibility across different platforms or devices, as well as any industry standards or regulations that need to be followed.
Tip: When detailing technical requirements, be as specific as possible. Include precise metrics, such as “the product must handle 10,000 simultaneous users without performance degradation,” or “the API response time should be under 200 milliseconds.” Clearly define any compatibility or performance standards to ensure smooth development.
7. Define User Experience and Design
Defining user experience and design allows you to outline how the product will interact with and be perceived by its users. This includes specifying what overall look and feel, navigation structure, usability considerations, and interactive elements align with user needs and expectations. Key aspects to consider include user personas, user journey mapping, wireframing, prototyping, accessibility requirements, and consistency with brand identity.
Tip: Keep user experience and design simple and intuitive. Focus on the most important interactions and ensure design choices align with your target audience’s needs and preferences.
8. Plan for Testing and Quality Assurance
This step involves defining comprehensive strategies and processes to ensure that the product meets specified requirements and quality standards. This includes outlining types of testing (such as unit testing, integration testing, and user acceptance testing), establishing criteria for success, allocating resources and timelines for testing phases, identifying tools and methodologies for testing automation, and determining roles and responsibilities within the testing team.
Additionally, considerations should include defining metrics for measuring quality, addressing potential risks and mitigation strategies, and integrating feedback loops for continuous improvement throughout the development lifecycle.
Tip: Start testing early and often rather than waiting until later in development. This can help you catch issues when they’re easier and less expensive to fix.
9. Consider Stakeholders and Communication
Outline comprehensive strategies and methodologies to ensure that the product meets specified functionality and user experience standards. This includes defining testing phases, such as unit testing, integration testing, and user acceptance testing, as well as establishing criteria for success and protocols for bug tracking and resolution.
Tip: Develop a communication plan to outline the key information each stakeholder needs and the appropriate timing for updates. This approach helps avoid overwhelming team members while keeping critical stakeholders in the loop.

Common Challenges
Creating a PRD can present some challenges, including:
- Ambiguity in requirements: Vague or conflicting requirements from stakeholders can lead to misunderstandings during development.
- Changing scope: Scope creep or evolving project requirements can affect timelines and resource allocation, requiring frequent updates to the PRD.
- Stakeholder alignment: Aligning diverse stakeholder expectations and priorities can be challenging, impacting decision-making and project direction.
- Technical constraints: Technical limitations or constraints, such as platform compatibility or integration complexities, may require adjustments to the PRD to ensure feasibility.
- Miscommunication between teams: Poor communication and infrequent check-ins can lead to teams working with outdated information or conflicting interpretations of requirements, resulting in rework and delays.
- Unclear or unrealistic goals: Setting vague or overly ambitious goals without considering resource constraints can derail projects from the start and hurt team morale.
- Changes in market conditions or competition: External factors like new competitor products or shifting consumer preferences can make your original PRD obsolete, requiring significant pivots. Regular market research and flexible planning help teams adapt quickly while maintaining project momentum.
Pro Tip: Regular, clear communication among stakeholders and using visual aids, like diagrams and prototypes, helps mitigate these challenges by fostering better alignment throughout the PRD development process.
