Product Requirements Document for Products and Software

The product requirements document (PRD) is a formal document that describes the features and functionalities of a product or software. It is used by engineering, product, and project management teams to define the requirements for a new product or software release. A PRD typically includes a high-level product description, a list of features and functionalities, user scenarios, technical requirements, and design constraints. The PRD is also sometimes referred to as a product specification document (PSD) or simply a requirements document (RD). 


Is it always necessary to develop product requirements documents (PRD)?



While the PRD is an important tool for product development teams, creating one is not always necessary or appropriate. In some cases, a product roadmap or high-level product requirements may be sufficient.

Product Requirements Document (PRD) Software – Doc Sheets 

There are many benefits of using Doc Sheets for your product requirements document. The most obvious benefit is that it can help you manage your product requirements more effectively, saving you time and money and improving the quality of your product.

Another benefit is that Doc Sheets can help you to automate some of the tasks associated with managing your product requirements. As a result, you may have more time to work on other aspects of the product development process.

Requirements management software Doc Sheets can also help you to track changes to your product requirements over time. This can help ensure that your product meets the needs of your customers or users.

Finally, Doc Sheets can help you improve communication between different stakeholders in your product development process. This can lead to better decision-making and a more efficient overall process.

What is a product requirements document?

A product requirements document (PRD) is a formal document that establishes the basis for an agreement between a development team and its stakeholders. It provides a shared understanding of the product to be built, what it looks like and how it is used.

A PRD typically includes:

– A high-level overview of the product
– A description of the target user and their needs
– A list of functional and non-functional requirements
– Use cases or user stories that describe how the product will be used
– Acceptance criteria that define when a requirement is considered to be met
– assumptions and risks that may impact the development of the product

Why are product requirements important?

Product requirements are important because they lay out the blueprint for what a product should be. Having a clear and concise product requirements document ensures that everyone involved in the product development process is on the same page and working towards the same goal.

Without well-defined product requirements, developing a quality product that meets customer expectations would be very difficult. The requirements document serves as a roadmap for the entire development process, from initial ideation to final testing and launch.

Well-defined product requirements also help to keep scope creep in check. If the team knows exactly what needs to be delivered, it becomes much easier to say “no” to requests for new features or functionality that fall outside the original scope.

In short, product requirements are essential for ensuring that products are developed efficiently and effectively and meet customer needs and expectations.


How to write a product requirements document

A product requirements document (PRD) is a formal document that describes the features and functions of a product or software. Development teams use it to plan and build new products or features.

The PRD should be created before any work on the product begins, and it should be reviewed and updated regularly as the product evolves.

Creating a PRD can seem like a daunting task, but it doesn’t have to be. Here are some tips for writing a great PRD:

1. Keep it concise
2. Be clear and specific
3. Include screenshots or mockups
4. Describe the user flow
5. Prioritize your requirements
6. Define acceptance criteria
7. Get feedback from stakeholders

Product Requirements Document – Agile Development

A product requirements document (PRD is an essential step in any agile project, as it ensures that everyone involved understands the vision for the product. The PRD should include a high-level overview of the product and more detailed information on each feature. It’s important to strike a balance between too much and too little detail – you don’t want the PRD to be so long that no one reads it, but you also don’t want it to be so short that it doesn’t give enough information. If you’re unsure what to include in your PRD, check out the following section for some tips.

As we know, agile development is based on the principle of iterative and incremental development, in which requirements evolve during the project. So it’s impossible to create a complete and detailed product requirements document (PRD) upfront.

But there are still some common elements in PRD for agile projects, which are listed as follows:

1. Product Overview: This part should give a high-level description of the product, including its features, target users, and market.

2. User Stories: User stories are brief descriptions of how users use the product. They are written from the user’s perspective and capture what the user wants to achieve with the product.

3. Acceptance Criteria: Acceptance criteria define when a user story is considered “done.” They should be specific, measurable, and testable.

4. Prioritization: Prioritization helps ensure that the development effort focuses on delivering users value as early as possible. Typically, user stories are prioritized using a technique called relative weighting.

5. Dependencies: Dependencies should be identified and tracked to avoid surprises or delays later in the project.

What should be included in a product requirements document?

When creating a product requirements document, it is essential to consider what information needs to be included to provide an accurate product overview. This can vary depending on the type of product, but some common elements should be included:

1. The problem that the product is solving: What need does this product fill? What are the user pain points that it addresses?

2. The target market for the product: Who is the primary audience for this product? What are their demographics and psychographics?

3. The features of the product: What does the product do? What are its core functions and capabilities?

4. The user experience of the product: How will users interact with the product? What kind of user journey can they expect?

5. The technical specifications of the product: What technology does the product use? What are its system requirements?

6. The planned timeline for development and launch: When does the team plan to have the product ready for release? Are any significant milestones or deadlines that need to be met along the way?

Tips for writing an effective product requirements document

    1. Keep it short and sweet: The product requirements document should be concise and to the point. It should not contain any unnecessary or superfluous information.
    2. Use simple language: The language used in the product requirements document should be easy to understand, and it should not contain any technical jargon or acronyms.
    3. Organize information logically: The information in the product requirements document should be organized logically, and it should be easy to follow and flow smoothly from one section to the next.
    4.  Include all relevant stakeholders: When writing the product requirements document, make sure to include all relevant stakeholders. This includes the development members, marketing personnel, and other individuals involved in bringing the product to market.
    5. Get feedback early and often: Throughout the development process, getting feedback on the product requirements document from all relevant stakeholders is important. This will help ensure that the final product meets everyone’s needs and expectations.

Product Requirements Document Development



Product requirements are the foundation of a software development project. They define what a product should be able to do, how it behaves, and how it looks. These high-level specifications are created early in the development cycle so that developers can start working on them without delay. A product requirements document (PRD) is an important part of this process. It should include all business objectives for your product as well as success criteria used by testers to evaluate if they have been met or not after implementing them into your application.


Executive summary

The Executive Summary is a high-level summary of the Product Requirements Document (PRD). It should be no longer than two pages and should capture the following information:

  • What is being described? This can include the application domain and use cases.
  • What are the key features of your product? This can include anything from a list of functionality to an overview of important aspects of your design.
  • What are some key benefits of your product? These benefits may cover areas like ease of use, security, performance, etc. However, they do not have to be limited only to those things—your team may decide that other factors have significant value in creating a compelling offering for customers or users.


Description of the current environment

Describe the current environment.

Include a description of the current system.

Include a list of the current users, their roles, and their contact information, if available.

List any vendors involved in the process, including any third-party software or hardware solutions.

List any suppliers involved in the project, including subcontractors and suppliers who might be used to accomplish tasks such as programming or testing.

List competitors who may be offering similar products or services to yours that can compete with yours either online or at brick-and-mortar locations (if applicable).

Problem statement

Problem statement:

  • Describe the problem you are trying to solve.
  • Include a description of the current environment (e.g., system architecture, infrastructure, dependencies, etc.)
  • Describe the problem you are trying to solve in the context of this environment. For example, if there is an excessive number of database queries on service X, describe why that’s happening and how it impacts users/the business.
  • Include a description of the solution you are proposing and how it should resolve these issues with minimal impact on existing systems or business processes.


Purpose of this document

The purpose of this document is to provide detailed specifications for the product requirements. This document is used in conjunction with other documents to describe all product design and development aspects comprehensively.

This document contains the following:

  • What should be included in the product requirements document (PRD)?
  • High-level overviews of each section within the PRD.
  • Detailed descriptions for each section, including information about what should be included, how long you should go into detail, and who needs to see it or use it in the project lifecycle.

Business objectives and success criteria (product vision)

The product vision is a high-level description of the purpose of your product and its intended impact on users. A cross-functional team should create it, ideally including marketing, design, engineering, and sales/marketing representatives.

The main reason for creating a product vision is to align everyone around understanding how the end user experiences your product. This should be done before you start developing features because it’s hard to build something that doesn’t serve its purpose or has no clear use case. A good product vision clarifies these questions: Why are we building this? What problem does it solve? How does it help our customers?

An excellent way to start building out your initial ideas for what your product could include is by asking yourself who would use it and why — then mapping out some possible scenarios for how they might interact with it in their daily lives. These scenarios give insight into what kinds of interactions people will have with whatever content you’re creating, which ultimately helps inform decisions about whether or not certain elements are necessary or even possible (like voice commands).

Functional requirements

Functional requirements are the features that a product must have. They can be broken down into two categories: system requirements and user requirements. System requirements describe the functions that the system must perform. These include things like how many users will be using it, whether it will be connected to other systems, and who will use it (e.g., doctors or nurses). User requirements describe the functions that users must perform with the system or measure how well they can perform them (e.g., a doctor entering information into a patient record and searching for information within that record).

Non-functional requirements

Non-functional requirements are not related to the product’s functionality and are usually not directly visible to the user. They’re often called “soft” because they’re not as easy to measure as functional requirements, but they can be just as important when deciding what features your software should have.

Non-functional requirements can be divided into quality attributes and additional constraints. Quality attributes are those things that directly affect how well or poorly your product works—things like performance, usability, and reliability. Additional constraints describe aspects of what you’re building that don’t directly impact how well it works but still affect its development: cost, time, and ease of maintenance are all additional constraints.

Glossary of terms, acronyms, and abbreviations.


  • A short form of a phrase or word
  • Used to shorten the written text, such as GSA for General Services Administration or FBI for Federal Bureau of Investigation.


  • An area of knowledge, study, or activity that has been named and given its own subject area classification. An example is economics.


  • A shortened version of a word or phrase. For example, “e-mail” is an abbreviation for “electronic mail.”

The PRD is a critical document for the product development process, as it includes all high-level requirements that must be implemented to ensure the final product meets user needs.

The PRD can communicate with developers and stakeholders at any stage in the product life cycle. A well-written PRD results in fewer misunderstandings between stakeholders, ultimately reducing risk and leading to successful products.


Different Requirements Documents


Product Requirements Document (PRD) Vs.  Business Requirements Document (BRD)

It is important to know the difference between a PRD and BRD when creating new products or services.

Regarding product requirements documents (PRDs) and business requirements documents (BRDs), there are a few key differences worth noting.

For starters, PRDs tend to be more focused on the technical aspects of a
product, while BRDs are more concerned with the overall business goals that a
product needs to achieve.

PRDs also typically include more detailed information about a product’s functionality and implementation, while BRDs tend to be more high-level in nature. Typically, product development teams develop PRDs, while Business analysts and stakeholders develop BRDs.

Finally, it’s worth mentioning that PRDs and BRDs can sometimes overlap in content, depending on the specific project or organization. However, these two types of documents generally serve different purposes and should be used accordingly.

Product Requirements Document (P
RD) Vs.  Marketing Requirements Document (MRD)


A product requirements document (PRD) outlines the
requirements for a new product. It is typically created by a product manager
and approved by stakeholders. The PRD includes the product’s features, target
market, and competitive landscape. A PRD is important because it ensures that
all team members are on the same page about the product’s goals and

The marketing requirements document (MRD) is a document that
outlines the requirements for a new product from a marketing perspective. It is
typically created by a marketing team and approved by stakeholders. The MRD
includes information such as the product’s position in the market, target
customer, and go-to-market strategy. An MRD is important because it ensures
that all team members are on the same page about the product’s marketing goals
and requirements.


Product Requirements Document (PRD) Vs.  Software Requirements Document (SRD)


A software requirements document (SRD) is a type of
requirements document used specifically for software projects. The document
contains the functional and non-functional requirements of the software, as
well as any other relevant information that would be useful for development. In
general, product requirements documents (PRDs) can cover both software and
non-software products. It includes information on the product’s features and
functionality, as well as any other relevant information that would be useful
for development or marketing. 

The main difference between an SRD and a PRD is their scope – an SRD is specific to software, while a PRD can be used for any type of product. However, both types of documents share many similarities, such as their focus on documenting user requirements.



A product requirements document is an essential tool for any product development team. Outlining the requirements for a product or software helps to ensure that everyone on the team is on the same page and that no critical details are overlooked. A well-crafted PRD can help make your product development process more efficient and streamlined, leading to a better end result.
