What Is a Product Design Requirement Document?

Product design documentation explains the process and reasons for creating a solution. Writing down requirements helps to form a design backlog, track improvements, measure outcomes, and simplify future integrations. When creating product design requirements, team members actively participate in planning, offering suggestions, or voicing their objections. 

A product design requirement document (PRD) is an artifact containing all the information needed to create a successful product. It follows the top-down methodology used in the Waterfall project management style. The document’s modification for Agile environments makes it easier for the product manager, software development team, and other stakeholders to collaborate to design and deliver products on schedule. 

This article explains how to write a design requirements document, reviewing its main sections and the challenges you can encounter while using this product specification. Finally, we will share the expertise of Artkai in product design, reviewing case studies like Accel and KMC Commander to showcase how efficient documentation optimizes building winning solutions. 

Core Elements of a Product Design Requirement Document

Agile teams use a product design document as an interactive collaboration method to align on crucial product elements. The PRD is developed based on the product's needs, features, and deadlines. Here are the vital sections to include in your product design documentation: 

Project Objective

This section outlines the purpose, vision, and goals of the product. An objective has to be a precise, measurable, and inspirational outcome you aim to achieve for your customers and business. It implies listing all the required product features to satisfy your consumers’ needs and business goals.

Project Details

You write down essential stakeholders, release dates, project progress, qualities, attributes, features, and other relevant information here. This part acts as a guide for designing, developing, and testing the final product.

User Stories

This section states product features in user stories that describe what a user wants to achieve. User stories address the expected user value of the product, giving designers and engineers a clear understanding of the precise guidelines they need to follow. Agile methodologies employ them to determine the essential functions to make a product functional.

User Flow and Design

A user flow visually represents your customers’ journey through a website or application, outlining their steps and what happens there. Describing a user flow helps to understand how consumers engage with your product. Knowing it lets you decide what actions a user needs to take to complete a task and how to best guide them through your solution.

Product Metrics

Support each assumption with a corresponding metric. Product metrics are measurable data points that a company monitors and evaluates to determine the performance of its offering. Some product metrics are conversion rate, churn rate, and monthly recurring income. In this section, you need to form a hypothesis regarding the impact of particular product functionality. User interactions with the feature will determine the success rate of your thesis.


A product roadmap is a source of truth used to describe a product's long-term goals, priorities, and progress. This section outlines future roadmaps that will assist in scheduling the essential tasks and milestones for the product's success. It makes the product's future software development more apparent to the team and stakeholders.

Pitfalls of Using a Product Design Requirement Document

When drafting a product design document, the following difficulties could arise: 

Getting Outdated

Most product teams work under tight deadlines. After assessing documentation and consulting with other members or stakeholders, it can be challenging to go back and amend the requirements. As a result, the data and inputs the development team uses can differ from the information stated in the product design requirement document.

Lack of Engagement

The frequency with which team members review or update the product design requirements depends on the company's culture and usual workflows. Ideally, team members should regularly check the requirements specification to ensure the document aligns with the team’s objectives. In practice, there can be a lack of interest or participation in the process.

KMC Commander: Unified IoT Platform

KMC Controls is an independent American manufacturer of open, secure technology and automation systems. The company contacted the Artkai team with a request to create a solution with a single dashboard that would allow them to manage various aspects of air quality. Their present system was outdated, unstable, and had significant UX issues. 

Our team audited and revamped the current solution to produce a universal, accessible, and modern solution. The system dashboard should be simple to use and easily adaptable to the scale of the client. We formed a comprehensive and detailed product design requirement document that helped us align cross-team collaboration. 


As a result, we created revamped KMC Commander with a single dashboard, which became a strong foundation for a modern smart building environment. A well-thought-out infrastructure made it simple to connect with 150+ partners, including prominent corporations like Intel and Amazon. The platform redesign had excellent outcomes for our client:

  • 35% growth in average users;
  • 1,5 decrease in turnover rate. 

Accel: Decentralized Trading Application

Our client, a fintech company that offers advanced trading tools for DeFi traders named Accel, had an idea for a new product that would improve the ecology of its current products. It was supposed to be a desktop application providing clients with a safer and more practical trading alternative. 

The Artkai team had to design a fully working revenue-generating solution for a closed community and cutting-edge bot technology to protect users' assets. Forming and updating a product design requirement document let design and develop the product simultaneously after the research and discovery phases. As a result, we created a user-friendly decentralized trading application that increased platform usage.
